Use the Time On and Counts property.
Tags are used to define data source communications, alarm limits, and other real-time signal properties like Time On and Counts for keeping track how long a point has been on and how many times it has transitioned in a given period. Tags are common data sources to all clients. Data Sources can be setup to communicate with Modbus, Allen Bradley, Siemens controllers, MQTT, and OPC Servers.
To use data directly from a Visual Studio application use the default data source of Value as a fixed value that can be changed using the OPC Controls Data component. Tags can also be used to setup Calculations from other local and remote Tags.
The following section is how to manually add and define Tags using the Configure OAS application. Tags can also be added and modified using the CSV Import and Export selections using the Configure-Tags application to use Excel or other third party Comma Separated Variable editor.
To learn how to programmatically add or modify Tags from your own Visual Studio application refer to the following article on how to add and define multiple tags with one method:
OAS System Config – Get and Set Tag Properties
For a complete list of all Tag properties refer to the OAS Configuration – Tags section in this help file./sdk/articles/oasconfig04.html
Please view the Getting Started with Open Automation Software Video to familiarize yourself with installation, setting up Tags, selecting Data Sources and Destinations, and implementing Networking and Security.
Start Configure OAS application from the program group Open Automation Software.
Select Configure-Tags.
Select the Local OAS Service by selecting the Select button.
Note: The Configure application can be used to connect to remote systems using the network node name or IP address of the remote node the OAS Service is running on. Simply enter the IP Address or network node name of the remote OAS Service you wish to connect to and click on the Select key.
Note: When selecting a service if you receive a warning dialog that the service cannot be retrieved make sure the OAS Service, OAS Data Service, and OAS Database Service are started as described in Start Service.
If you already have the default Demo Tags loaded you can right in the list of tags to the right to Delete All Tags.
Click on the Add Tag button located at the top of the Tag browser.
Note
You can also add organizational Groups as many levels deep as you prefer and add tags to groups. To do this first add a Group to the root level, then right click on the Group in the right window to add additional Groups or Tags.
Enter the Tag name Ramp in the Add Tag dialog box.
Repeat Steps 4 and 5 with Tag name Sine.
Repeat Steps 4 and 5 with Tag name Random.
Select Tag Ramp in the right Tag window.
All Tag properties will appear in the lower window.
For the Value Parameter set the Data Source to OPC Item.
Use the OPC Browse button at the right of the OPC Item to browse OPC Servers.
Expand Local to expand EEI.OPCSimulator and select SimDevice.
Select Ramp from the list of OPC Items and select OK to enter the OPC Item EEI.OPCSimulator\SimDevice.Ramp.
If you plan to use trending on this point enable the Trend Point option in the upper right of the Tag Properties window.
Set the Description field to Ramp.
Select the High High Parameter and set the Value field to 80 and enable the High High alarm.
Select the High Parameter and set the Value field to 60 and enable the High alarm.
Select the Low Parameter and set the Value field to 40 and enable the Low alarm.
Select the Low Low Parameter and set the Value field to 20 and enable the Low Low alarm.
Select the Apply Changes button in the lower right corner.
Select Tag Random and the Value Parameter.
Repeat Steps 8 through 14 and Step 19 substituting Ramp for Random as Tag name and OPC Item name.
EEI.OPCSimulator\SimDevice.Random.
Select Tag Sine and the Value Parameter.
Repeat Steps 9 through 19 substituting Ramp for Sine as Tag name and OPC Item name. Use 0.9 for High High Value, 0.8 for High Value, 0.2 for Low Value, and 0.1 for Low Low Value.
EEI.OPCSimulator\SimDevice.Sine.
Select the Save button on the toolbar at the top.
Create a directory on the local C:\ drive with the name OASDemo.
Save the file DemoTags.tags in the directory C:\OASDemo.
Under Configure – Options set the Default Tag Configuration File so when the computer restarts the tag file will automatically be loaded.
For a quick tutorial on configuring tags view the Quick Start Example – Configure Tags section or view the following video:
The following video was created from earlier versions of OAS, but is still applicable for those data sources shown in the video to familiarize yourself with installation, setting up Tags, selecting Data Sources and Destinations, and implementing Networking and Security.

Select the OAS Service that you desire to import a CSV file to the Tag configuration and click the CSV Import button on the top menu to import a Comma Separated Variable file.
Use the Export CSV feature to generate a CSV file. You can then use Microsoft Excel or other CSV compatible application to add or modify Tags. Only the Tag name is the required field.
You can select to include or exclude all other fields. Only those fields that are found in the header will be used to update the properties of the Tags. If a Tag already exists it will be updated. If the Tag does not exist it will be created. Existing Tags that are not specified in the CSV file will not be updated or deleted.
The same tag parameter structure can be used to programmatically define tags with the TagCSVImport method on the free to use OASConfig and OPCSystems components. This is demonstrated in .NET Server Configuration-CSV Import and Export example.
Select the OAS Service that you desire to extract the Tag configuration from and select click the CSV Export button to generate a Comma Separated Variable file.
You can then use Microsoft Excel or other CSV compatible application to add or modify Tags. Use the Import CSV feature to then import the modified CSV file.
If you wish to just export a particular Tag Group, right click on the Tag Group and select Export to CSV.
Use the OPC Systems component in your Visual Studio application to programmatically modify Tag and Tag Groups.
Refer to FormConfigureCSV, FormConfigureGroups, and FormConfigureTags Forms in the WinForm Example Code example for an example and how to add and modify tag.
To learn how to programmatically add or modify Tags from your own Visual Studio application refer to the following article on how to add and define multiple tags with one method:
View the following video for explanation of each parameter and how to enable Time On And Counts:
When this feature is enabled in a Tag Value or Alarm Limit it will keep track of how long a Boolean value is true and how many times it transitions to True.
The Time On and Counts feature will keep track of the following:
The following image shows how the points will appear for connection in a client if the High High Alarm Limit is enabled for Time On and Counts. You can also use Value or any other Alarm Limit.
The time of day that the day should end to reset the Time On and Counts.
The amount of time in minutes to keep track of for Time On and Counts for Period 1 time.
The amount of time in minutes to keep track of for Time On and Counts for Period 2 time.
When defined to a Boolean tag the Time On and Counts totals will be reset with the tag is True.
To retain the Time On and Counts totals after a system restart go to Configure-Options-Retain Values and enable to retain Time On and Counts to a file.
