The Power of an Open Architecture

A comparison of features and benefits of an open architecture platform vs. an off-the-shelf solution for Industrial Automation and IoT

In IT it has become almost axiomatic that it’s cheaper to purchase an off-the-shelf solution instead of building your own application from scratch. A custom piece of software can very expensive because it is being built for a single purpose and with one customer in mind. It usually takes much longer to get up and running and to work out all of the bugs.  But developing custom software is still embarked upon because it comes with some significant benefits, especially if you are an OEM, interested in reselling the solution.

What if there was a software platform that provided the benefits custom development, but also mitigated the risks of rolling out your own solution, and even dramatically reduced costs over time?

So let’s explore this a bit further, breaking down the pros and cons of both custom development  and off-the-shelf products. We’ll then demonstrate how the OAS Platform is unique in the IIoT space and what an open architecture can do for you.

Off-The-Shelf Products

The pros and cons of off-the-shelf (OTS) or “canned solutions”, which may still include some tools for designing HMI screens and logic, but within proprietary environments.

PROS

Rapid configuration

One of the most attractive features is the relative ease at which OTS products can be configured and deployed since the feature set and tools are well-defined.

Built-in tools and applications

In order to speed up and simplify deployment, most OTS products include many tools for creating things like HMIs, and often have full-blown applications ready to be used in production.

Generally well-supported

Coming from many well-established companies, these products usually come with a team of support personnel and documentation, which usually comes at an additional cost.

Great for demos or proofs-of-concept

When an OTS platform is narrowly focused on a solution domain, and when tools and applications are proprietary, these products are impressive during tightly controlled demos. Little or no programming is required to get up and running.

CONS

Difficult (or impossible) to customize

Once you start using these products, you’ll quickly find that you need some functionality that they do not provide within the basic toolset. So then you must resort to using APIs with some custom development to extend them. Other times, customization is not even possible.

Strict licensing, difficult for OEMs

To protect their intellectual property and branding, software vendors tend to limit OTS platforms by the number of users connected to them, and it can become very expensive and restrictive very quickly for OEMs, making it difficult to fit these products into your business model.

Proprietary data format

Another way license restrictions are enforced is to lock down the data within the system. OTS vendors provide tools for importing or exporting data, but the data is usually stored in a proprietary format.

Proprietary tools and user interfaces

If your requirements are to generate an application with a specific user interface, you may find an OTS solution limiting. Many of them provide a large library of symbols and objects, but your application will look like many others, and will unlikely include your own company branding. You’re also required to use the vendors tools for configuration and modification.

Specialists are expensive and scarce

OTS vendors generally sell to a niche market, so while the install base and investments may be large, the actual number of individuals with the skills to use the software is a small pool relative to the global software and IT community. Few consultants have the necessary skill to work with each OTS product, and if so, come at a high price even when they are available.

You’re paying for features you don’t need

Most of these products have wide variety of features, but since they’re developed for most situations and not just yours, you end up paying for features you will never use. During an evaluation of an OTS product, the number and depth of features is a selling point, but are rarely ever used in production.

Custom Development

The classic alternative to off-the-shelf products is a fully customized application developed from the ground up. Like a well-tailored suit, this can be the best fit for your needs, but comes with its own challenges. And just like a well-tailored suit, custom software development doesn’t always respond well to size and scope changes.

PROS

Fully Customizable

Since the solution is developed for your specific needs, it can contain any feature you require and nothing else

Open data formats

You can choose your data store, and are not locked into proprietary tools for import/export, or license restrictions on your own data.

Affordable and highly available resources

Choosing your own development languages and tools also means that you can create your custom solution using ubiquitous technologies. Software engineers and consultants are abundantly available at reasonable prices.

No licensing restrictions

If the solution is yours, your only licensing restrictions would come from any contracts established with your development team and any underlying technologies utilized in the development of the architecture.

Use any data source and data store

Utilizing APIs and communication protocols within custom development means that almost any device and data source can be integrated. Also, every open data store can be used and even mixed within a custom solution. This makes the underlying data available at any time for real time monitoring, historical analysis, and reporting using the tools of your choice.

Can host any user interface

Since the data is open, this also means any possible user interface can be developed, with your own company branding, which is necessary for OEMs and software resellers.

CONS

Upfront development may be required

With a custom solution, there’s no avoiding it. The software needs to be developed and tested before it can be rolled out into production.

No built-in user interface or apps

Because you’re starting with a blank slate, you can have any interface you would like, but that means none exist. All of the interfaces and tools need to be created.

Requires customization when requirements change

If your company grows, your requirements change, or you realize that your original assumptions were not entirely correct, the solution must be modified. Whenever a custom solution needs modification, that usually means more custom development, unless the modifications were planned upfront.

 

A Third Way: The Open Architecture

The OAS Platform is a robust alternative for building an Industrial Automation or IoT solution. The Platform mitigates many of the risks of pure custom development, while still offering all of the advantages of a custom solution. How is this possible? OAS provides a robust and scalable networked platform that can be connected to data sources and data stores, all through a set of configuration applications. At the same time, the OAS platform exposes a series of APIs and developer tools for the creation of custom applications and the complete automation of the entire system. The following are just a few of the features OAS offers:

Universal Data Connector

The UDC is a server platform that manages connectivity to devices, databases, file systems and more. It also includes native drivers for many standard PLCs and IoT components that can be connected and configured with no programming required. The UDC is able to be networked with other instances, distributing and aggregating data as needed at the fastest speeds possible.

Learn more about the Data Historian 

Automated configuration and deployment

Every aspect of the server configuration can be automated using the various APIs that are exposed for .NET and REST clients. This means an OAS Platform can be programmatically configured and deployed, dramatically reducing costs for rolling out new installations when your organization or install base grows.

Learn more about OAS Developer Tools and APIs 

Infinitely customizable using open development tools and APIs

Access to the OAS APIs and development components is available using open tools and with popular development environments and languages. Desktop applications can be written in any .NET language using Visual Studio. Many visual components are provided for both WinForms and WPF for real time data access and control, as well as for Trend and Alarm visualization. Web application developers can use the Web HMI, Web Trend, and Web Alarm products to deploy web-based visualizations on any web platform and any web browser, desktop or mobile. And using the PCL components, native iOS and Android applications can be integrated into your solution.

The UDC also exposes several APIs for automation and customization. Software developers are free to build their own user interfaces using completely custom code, or they can use the many tools and controls provided for desktop, web, and mobile applications.

Fix IoT Cloud Leaks

What’s not to like about Cloud based IoT Platforms?

Nothing, if you are comfortable with relying on other services and infrastructure to manage, maintain and secure your data. If lost or missing data is OK, if someone misses a notification of a song download or about a new product release, or maybe even if you are low on milk. But if you rely on up-to-date real-time data for critical decisions, then current cloud-based IoT platforms may not be the best choice.  When seconds count, are you sure of your IoT infrastructure provider?

A few of the major questions or concerns with the current cloud-based IoT platforms are:

  1. Connectivity. How do I get my data from my devices to the Cloud based IoT environment? A lot of industrial devices do not support IoT protocols. Do I have to replace all of these devices that I have invested in just to get my data to Cloud? What if my data source is a spread sheet, a database or an existing application? What if I want to perform calculations on the data prior to transmission?
  2. IoT Protocol. There are more than a few. Which do I choose? Since it will be a large investment, what happens in a few years if there is a new protocol required by my IoT provider? Will the old protocol still work or will I have to reinvest in converting all my devices to the new protocol. If I decide to switch to a different cloud-based IoT provider, will my existing devices / system still work?
  3. Security. Is my data going to be secure from hackers, and who is controlling my data? What 3rd party partners will have access? Is SSL secure? How about TLS? Which one will work with my IoT Provider? How do I manage the certificates required by my cloud-based IoT provider? How secure are the cloud-based servers? The major players in the IoT arena are a prime target for hacking because of the wealth of data available and the visibility of their servers and infrastructure, so a single breach could expose thousands of customers including you.
  4. Reliability. What happens when the Internet connection or the cloud-based servers go down? Will my organization be blind for decision making? What happens when my cloud based IoT provider is under a DDOS attack? Will I be losing data that can’t get transferred to the cloud?
  5. Pricing. What happens if my provider decides to raise its subscription price or worse yet decides to get out of the IoT market? For the big players, IoT is just a side business.
  6. Tools. What tools can I use to access, display, analyze, and store my data? Only the tools provided by my subscription?

What if there existed a platform that provides you all of the advantages of connecting not only to IoT specific devices and platforms, but literally 10s of thousands of existing real time and legacy devices? What if this platform could rapidly, securely and cost-effectively transfer millions of data points per second and insure that you have all of the data maintained even when the communications between the source and destination is down, while providing N levels of redundancy?  And better yet, what if it didn’t rely on 3rd parties services to handle and disseminate your data, allowing the platform to be completely managed by your own IT department or hosted in the cloud? What about a platform that offered interfaces to SQL Server, Oracle, MySQL database and the ability to generate real-time and historical applications based on .Net, HTML, JS, and iPhone and Android OS?

Open Automation Software Solution

What is Big Data?

Buzzword or not, Big Data is definitely not a passing fad or something that forward thinking businesses can ignore.

At first glance the Big Data concept seems self-explanatory. Big Data, as the name suggests, is surely all about very large quantities of data.

Big Data certainly involves vast quantities of data, usually in the region of petabytes and exabytes. But the size of the data set is just one facet of Big Data.

Characteristics of Big Data

 

In 2001 Douglas Laney began the process of defining the emerging concept of Big Data. He did so by identifying three defining characteristics of Big Data:

  • Volume
  • Velocity
  • Variety
  • Veracity*
What is big data? Big data concept Volume, Variety, Velocity and Veracity

*Laney originally posited 3 characteristics but over time other ‘Vs’ have been added. Here we include the extra characteristic of Veracity

Volume

Volume refers to the quantity of data generated and stored by a Big Data system.

Here lies the essential value of Big Data sets – with so much data available there is huge potential for analysis and pattern finding to an extent unavailable to human analysis or traditional computing techniques.

Given the size of Big data sets, analysis cannot be performed by traditional computing resources. Specialized Big Data processing, storage and analytical tools are needed. To this end, Big Data has underpinned the growth of cloud computing, distributed computing and edge computing platforms,  as well as driving the emerging fields of machine learning and artificial intelligence.

In dealing with these large volumes of data, the big data computing system needs also to be able to reliably detect critical and/or missing data – see Veracity below.

Variety

The Internet of Things is characterized by a huge variety of data types. Data varies in its format and the degree to which it is structured and ready for processing.

With data typically accessed from multiple sources and systems, the ability to deal with variability in data is an essential feature of Big Data solutions. Because Big Data is often unstructured or, at best, semi-structured one of the key challenges is the task of standardizing and streamlining data.

Products like Open Automation Software specialise in smoothing out your big data by rendering data in an open format ready for consumption by other systems.

Velocity

The growth of global networks and the spread of the Internet of Things in particular means that data is being generated and transmitted at an ever increasing pace.

Much of this data needs to be analyzed in real time so it is critical that systems are able to cope with the speed and volume of data generated.

Systems must be robust and scalable and employ technologies specifically designed to protect the integrity of high speed and realtime data. handle the rate such as advanced caching and buffering technologies.

Big Data systems rely on networking features that can handle huge data throughputs while maintaining the integrity of real time and historical data.

Veracity

Data quality and validity are essential to effective Big Data projects. If the data is not accurate or reliable than the expected benefits of the Big Data initiative will be lost. This is especially true when dealing with realtime data. Ensuring the veracity of data requires checks and balances at all points along the Big Data collection and processing stages.

Complexity can be reduced through automated systems. An example of this is Open Automation Software’s One Click automated setup feature that can quickly scan a server and automatically configure huge numbers of data tags without the risk of human error.

Accurate queuing and buffering of data, timestamping and and the use of the most efficient communications protocols go a long way to ensuring the veracity of data.

What is Google IoT Core?

what is google iot core

Industry 4.0 Data with Google IoT Core

Google IoT Core is an Internet of Things (IoT) service from Google that allows businesses to manage their IoT infrastructure and data. Google IoT Core is comparable to Amazon’s IoT Gateway and Microsoft’s Azure IoT Hub.

The key elements of Google IoT Core include:

  • Device management – an interface for managing and authenticating ‘things’ or devices
  • Protocol bridge – provides the connection endpoints and management services needed to provide secure and reliable telemetry.

OAS Google IoT Core Interface

Always on the leading edge of Industrial IoT technology, OAS now includes support for Google IoT Core. Moving data from your local or remote data sources to (or from) Google IoT Core is straightforward with OAS. It doesn’t matter what the data source – with Open Automation Software you can move it to and from Google’s IoT Core framework.

 

Use the OAS Google IoT Core Interface to quickly, efficiently and securely move data to and from Google IoT Core and other systems. There’s no limit to the type and quantity of data you can move with OAS. Production data, energy monitoring, inventory, GPS data and more can all be automated with OAS. Harness your data to improve overall equipment effectiveness and improve supply chain efficiency.

What is Google iot core

Data quality is a high priority for IIoT Applications

For Industrial Internet of Things applications, data transfer has to be secure, accurate and fast. With OAS, data quality is verified via timestamp using MQTT. Take live local, remote or plant floor data and easily use it in big data analytics.

Write live data to devices within Google IoT Core using OAS’s built in MQTT protocol driver. This enables you to take full advantage of any or all of the other big data and IoT services provided by Google IoT Core. You can complement Google IoT Core with other OAS products; our Data Historian product is an easy and reliable way to move data to Google IoT Core.

MQTT – A Highly Efficient Protocol for Remote Devices

OAS Google IoT Core interface utilizes MQTT, a lightweight protocol that implements a client/broker architecture. Originally developed as a machine to machine (M2M) protocol by IBM, MQTT is now implemented in several open protocols.

Due to its client/server architecture and its small footprint MQTT is particularly well suited for small devices with limited power or network connectivity. A common application is to use this protocol on hundreds or thousands of remote devices that may have battery or solar power and be utilizing cellular or other limited or expensive communications.

Advantages of MQTT

  • Small packet size = low overall bandwidth usage
  • Great choice for limited connectivity – remote device connects to the broker when possible and publishes its updated state
  • Able to both subscribe and publish to brokers making it easy to take remote device data and View, Historize, Alarm, Trend and Notify via Web, .NET, Email, Voice and SMS.

Share non machine to machine (M2M) data and share it with M2M devices and clients utilizing the analytics available on Google IoT platform.

5 Common Failures with Data Logging and Alarm Logging

Knowledge of common failure points helps guide data logging system design

In selecting a data logging and alarm logging solution it is best to consider what happens to the data when everything is not performing perfectly.  In a system’s lifetime at least one of the following if not all five will occur multiple times:

 

1. Database Engine Failure
2. Network Failure
3. Missing High Speed Data
4. Inaccurate Manual Setup
5. Defective Controller Handshaking

Database Engine Failure

When the connection to the database engine fails during database backup, maintenance, or network failure to remote engines data will be lost if the data logging and alarm logging solution does not provide store and forward functionality.For systems that do have store and forward capabilities it is important to select one that can maintain the data for long periods of time.  This requires that the data to be inserted or updated to the database must be stored to disk instead of just buffered to RAM.

Steps to replicate condition:

  1. Stop database engine during data logging and alarm logging.
  2. Verify data buffered to disk.
  3. Start database engine.
  4. Verify all data has been archived before, during, and after database engine shutdown.

Note: An advanced test to account for a system restart during data buffering is to shutdown and restart the logging server between steps 2 and 3.  Most store and forward solutions will lose data if the server PC is shutdown.

Network Failure

When the network connection between the data source server and data logging server is down, data will be lost if the solution does not implement a distributed network design with store and forward at the data source. By relying on cloud solutions for data and alarm archiving data will be lost when the connection to the data source is broken and data cannot be sent to the cloud solution.  Also there are many tunneling solutions that provide network transport, but do not maintain the data during network outages.

Steps to replicate condition:

  1. Disconnect network between data server and cloud system or remote data logging server.
  2. Verify data buffered to disk at the source.
  3. Reconnect network.
  4. Verify all data has been archived before, during, and after network outage.

Missing High Speed Data

It is important for a logging solution to provide data processing right at the source and process all values received from the data source.  Data and alarms can be missed if data transitions quickly and the solution processes only the current value sampled.Consider a sensor that receives a sharp spike in data for a very brief time interval.  If sampling occurs before and after the spike, no alarm would be recorded and the high data value would be missed in the data archiving.  Some systems can sample at a much faster rate, but then have problems moving the large amount of data to the database engine efficiently and then data begins to backup in the system.  It is important to select a system that can handle high bursts of data during critical events.

Also data that is processed directly within the controller can be queued to be handed over to a data logging system.  It is important that the data logging solution have the ability to provide handshaking to the controller to inform when the data is received and processed and ready for the next record.

Steps to replicate condition:

  1. Use a data source of a .NET application or high speed communications that can provide time stamp and data at high rate, microsecond samples if possible.
  2. Have the data change cycle below and above alarm conditions a series of times.
  3. Verify that all data samples are recorded to the database, and all alarm events have been captured and recorded.

Inaccurate Manual Setup

Automated or programmatic setup is important in system setup so human error does not affect the system accuracy of what data is logged and alarmed upon.  With large amounts of data to be collected and processed it is very easy to point to the wrong variable address, alarm limit, or database field.Steps to verify setup accuracy:

  1. Insure there is automated or programmatic setup of the data source, data logging, and alarm logging configuration.
  2. Use a CSV Export to spreadsheet and verify each row for data addresses and field names match.

Defective Controller Handshaking

Some systems will queue data in the controller for best data accuracy and assurance of no data loss on communication failure to the controller.  This is typically done with a queue or array within the controller where the data is buffered and then passed to the data logging engine when it is available to record the data.  It is important to enable a handshaking technique that can validate data has been successfully archived.Steps to verify accuracy:

  1. Start the controller cycles processing records to be logged
  2. Stop database engine.
  3. Have controller execute several cycles of records to be logged.
  4. Start database engine.
  5. Verify that no records are missing from the cycles performed before, during, and after the database engine shutdown.

6. Alarm Notification

Alarm Notification on data logging or alarm logging failure. OAS can call personnel via phone or send a text message and email when data buffering is active.  Even though OAS can store many years worth of data to disk to restore the database engine it is best to be notified immediately when there is a problem.
View the following video on how to setup email notifications.
https://www.openautomationsoftware.com/videos/#send-alarm-emails

7. Controller Handshaking

Controller Handshaking to communicate with the controller to provide confirmation that the data is received and ready for the next record. Within OAS logging there are confirmation and error feedback status that can be updated to live tag values for both alarm notification and to be sent directly back to a controller for closed loop data handshaking.

What is an IoT Gateway?

IoT Gateways – Powering the Industrial Internet of Things

As the Internet of Things expands, businesses find themselves faced with the challenge of integrating a multitude of devices and protocols, many with varying  power and connectivity requirements. This mix may also include legacy technologies.

IoT Gateways are emerging as an essential component in building a robust IoT and for delivering computational power in edge computing scenarios.

What is an IoT Gateway?

An IoT Gateway is a solution for enabling IoT communication, usually device -to-device communications or device-to-cloud communications. The gateway is typically a hardware device housing application software that performs essential tasks. At its most basic level, the gateway facilitates the connections between different data sources and destinations.

A simple way to conceive of an IoT Gateway is to compare it to your home or office network router or gateway. Such a gateway facilitates communication between your devices, maintains security and provides an admin interface where you can perform basic functions. An IoT Gateway does this and much more.

 

 

What functions does an IoT gateway perform?

IoT Gateways have evolved to perform many tasks, from simple data filtering to visualization and complex analytics. These smart devices are helping power the current wave of IoT expansion.

IoT Gateway feature set

A versatile IoT Gateway may perform any of the following :

  • Facilitating communication with legacy or non-internet connected devices.
  • Data caching, buffering and streaming
  • Data pre-processing, cleansing, filtering and optimization
  • Some data aggregation
  • Device to Device communications/M2M
  • Networking features and hosting live data
  • Data visualization and basic data analytics via IoT Gateway applications
  • Short term data historian features
  • Security – manage user access and network security features
  • Device configuration management
  • System diagnostics

IoT Gateways and Edge Computing

In edge computing, critical data processing occurs at the data source rather than in a centralized cloud-based location. A versatile IoT Gateway is the essential link in delivering edge computing power to technicians in the field or at the plant floor. IoT Gateways that come equipped with these capabilities are referred to as ’Smart’ Gateways.

IIoT Edge Computing vs. Cloud Computing

As enterprise data sources becoming increasingly decentralized, the shortcomings of cloud-based architectures tend to rise to the surface.

What is Edge Computing?

In edge computing, critical data processing occurs at the data source rather than in a centralized cloud-based location. Other terms sometimes used to describe edge computing include ‘fog’ computing and grid computing.

The Industrial Internet of Things (IIoT) relies on data from many sensors, controllers and attached servers, often across multiple, remote locations. Certain data processing tasks are best performed ‘at source’ rather than in the cloud.

 

Why cloud solutions (on their own) are not suitable for realtime IIoT data

With typical network cloud systems, data is pushed up to a server and then pulled back down by clients. This works well for videos, pictures, music, documents and non-critical applications, but is not a good design for realtime IIoT data. If data does not reside at the source, the data quality may be unreliable. Issues with the freshness, accuracy of data, and speed of delivery are potentially impacted when using a cloud architecture.

When supporting a complex IIoT solution, a centralised cloud architecture becomes costly in terms of bandwidth cost and computing resources. Latency and network availability issues also impact cloud based IIoT.

Comparing Edge and Cloud Network Architectures

Edge Computing

  • Basic data visualization
  • Basic data analytics and short term data historian features
  • Data caching, buffering and streaming
  • Data pre-processing, cleansing, filtering and optimization
  • Some data aggregation
  • Device to Device communications/M2M

Cloud Computing

  • Complex analytics
  • Big Data mining
  • Sources of business logic
  • Machine learning rules
  • Advanced visualizations
  • Long term data storage/warehousing

 

Example – Edge Computing in the Field

Technicians working on a remote wind turbine use edge computing to view basic data and analytic information in the field. The essential data needed to diagnose the turbine is more efficiently delivered in the field without having to rely on patchy cellular communications with a cloud based solution.

Processing power is provided at the data source or ‘edge’ via standard PC hardware or other IIoT gateway devices. The centralized cloud platform is still utilized for more resource-intensive analytics, stored business logic and data warehousing.

The Business Case for Edge Computing

The business case for edge computing is driven by cost savings in computing power and bandwidth as well as its ability to provide faster and more accurate access to automation data at its source.

For many IIoT applications, edge computing is the  reliable and cost-effective way to ensure data quality,  freshness, accuracy and speed of delivery. Other factors such as the quantities of data transferred and bandwidth costs  will determine the ultimate mix cloud and edge services.

 

Which network architecture is right for your business?

Edge computing and cloud computing are complementary architectures that come together to create powerful IIoT platforms. One does not replace the other.

The best IIoT solution for your business will likely be a mix of the two architectures. Deciding which computing tasks should happen in the cloud or at the edge requires careful analysis of your business needs. Software providers like Open Automation Software are ideally placed to provide the software infrastructure for creating a world-class IIoT solution as well as providing advice on how to best design your edge computing platform.

  • and more

2. Data Processing

All data is processed and logged live at the source, with full store and forward. This means there’s no risk of data loss in the event of network failure. All your data is rendered in open format with resolution down to 100 nanoseconds.

3. Built On Distributed Network Architecture

Because our distributed networks use Live Data Cloud, you can host live data with any Windows PC without any risk of data loss that can occur with typical cloud architectures. Networking features allow you to forward, redirect and host data at the data source. You can send and receive data securely through any corporate network, even without internet access.

4. Data Transport and Security

Data is transported through a lightweight protocol using compressed, securely encrypted data packets. Full client and server confirmation of delivery of data at each end ensures the quality of data transported, and there is no limit to the number of security profiles you can create.

5. Data Destinations

You can visualize, analyze and deploy data within your organization, to any existing platform of your choice. This can be done through web, Windows, Smartphones, databases, and a variety of file formats. We provide your developers and system integrators full programmatic access to all data and configuration in open format. There’s also a range of free HMI symbols available for download, so your programmers can put together a visually engaging user interface.

See how an OAS system such as this came together for Allen Bradley Programmable Logic Controllers.

Cost-Effective Licensing

Our licencing is based on three simple factors;

  1. The number of tags you need to connect to
  2. The number of OAS products needed to connect your data sources
  3. Whether you need a networked or stand-alone system

You can still deploy unlimited client applications within each Distributed Network Architecture enabled server.

OAS Security

hex-security-feature-graphicHow our systems protect your data on networks

With any Open Automation Software, security is built in thanks to the way in which our network communications work.

Our system utilizes both hardware and software technology to protect your information. Data is sent through a lightweight protocol with compressed, securely encrypted data packets. These encrypted packets can be transferred at extremely fast speeds with multiple values in each packet.

The quality of your data is assured with full client and server confirmation of data delivery, end to end. There’s also individual user security setup on data servers, providing client access to live data, historical data, and configuration.

No data loss on network failures

One of the great benefits of hosting data directly from the source, is that in the event of network failure, there’s no data loss.

So, whether you’re receiving data, alarm and access logs, or monitoring production in a remote location, nothing is lost due to dropped networks.
