Citect OPCUA Client Driver - Configuring Subscription Sampling Interval to something other than double the subscription rate.

As mentioned in OPC UA driver help (OPCUA Driver > Advanced Configuration and Maintenance > Subscription Management) : "The driver sets the OPC UA subscription sampling interval equal to be half of the publishing interval."

Means setting the 400ms in Citect will cause the server to scan the PLC at 200ms, which could in cases overload to PLCs.

How can we modify default sampling interval setting in Citect?

We want to Configure Subscription Sampling Interval to something other than double the subscription rate.

    Thank you for this feedback. This would need to be an adjusted parameter within the OPC UA framework itself and would need an entry field for consideration. I am moving this to the Device Integration team for consideration into the R&D processes.
