Source time stamping is supported by firmware version 2.01 (and higher) of the BMENUA0100 module (BMENUA0100.2) in Control Expert.

To use source time stamping in an application, you need to enable then activate it.

After source time stamping is both enabled and activated, the BMENUA0100 module begins polling devices when there is at least one monitored item with Monitoring mode set to Sampling or Reporting in OPC UA client.

Enabling Source Time Stamping

Source time stamping is enabled in the Project Settings window. Navigate to General > Time > Time Stamping Mode then select System.

NOTE: The default Time Stamping Mode setting is Applicative. If you do not change the default setting to System, then a detected error is displayed when the application is built.

Activating Source Time Stamping

Use the IPConfig tab of the BMENUA0100 configuration dialog to activate and configure time stamping.

In the Source Timestamping section, configure the following settings:
