I'm using DSC to connect to RSLinx OPC. I would like to have the tags read on 30 second intervals to slow down network traffic. What do I need to do?

[Craig Cederquist]

I would like to be able to configure each group to a read interval. I've set the RSlink polled msg rate at 30000 ms but the opc client is forcing a read at a much faster rate, at least every second. I've tested with success the RSLINX OPC client to read every 30 seconds so I believe the problem is in the OPC client and not the OPC server. TIA, Craig

Craig,

You should be able to set the I/O group update rate in the Tag Configuration Editor for your tag in the Connection tab's I/O group configuration to 30 seconds. The OPC client would request on the OPC server a OPC group with this update rate and deadband settings. The OPC server should not send values faster than the update rate when the deadband is reached.

Does that help? - Please let me know

In addition to the tag config, I believe you can also set the update rate in the OPC servers.

Check ther also.
