Built for performance and flexibility, OAS supports advanced Modbus driver capabilities across industrial environments.
Extensive Device Support
All three Modbus protocols are supported on both Ethernet and Serial Port interfaces:
Modbus TCP, Modbus RTU, and Modbus ASCII
It also includes extended addressing and Enron protocol for legacy systems.
High-Speed Performance
Achieve update rates as fast as 15 milliseconds per packet. Automated packet optimization supports large data blocks exceeding 125 words for advanced Modbus TCP gateway applications. With parallel Modbus driver operation and support for up to 1,000,000 tags per server, OAS delivers high-performance Modbus data acquisition at scale.
Communication Statistics & Polling
Monitor communication status with live values or trigger alerts on failures. Polling can be continuous at an adjustable rate or event-based to minimize network load on bandwidth-constrained systems
Reliability
Adjust connection and transaction timeout settings to suit your environment. Ensure uptime with automatic recovery and automated failover support for redundant Modbus controllers.
Data Accuracy
First-in, first-out (FIFO) data processing preserves historical integrity, ensuring complete data accuracy in time-sensitive environments.
Common Use Cases
OAS enables flexible Modbus integration across databases, applications, and industrial systems.
Log Modbus Data to Databases and CSV Files
Use our Modbus data acquisition software to write data from Modbus devices to SQL Server, Oracle, MySQL, PostgreSQL, SQLite, and others. Trigger logging based on events, value changes, or continuous polling. The system also supports logging high-speed buffered data from a controller. Learn more.
Transfer Modbus Data
Transfer data between Modbus TCP gateways, devices, and Industry 4.0 systems using our Data Route feature.
Transfers can run on a local area network (LAN), a wide area network (WAN), or the Internet, with secure cloud and edge networking options. Learn more.
Modbus User Interface
Create Human Machine Interfaces (HMIs) for Modbus data using our no-code UIEngine, with drag-and-drop tools.
Build WinForms HMI, WPF, or Web HMIs, or extend with .NET and REST APIs. It’s a complete solution for your Modbus HMI software needs. Learn more about the UIEngine
