Dear experts,
I have the following setup:
CPU-313C (6ES7313-5BF03-0AB0 V2.6) + CP343-1 (6GK7343-1EX30-0XE0 V2.0) communicating with Siemens PC HMI (not sure what protocol it's using) and Kepware OPC server (TCP/IP) via RJ-45.
When both OPC and HMI are acessing data (1~2s window between two data access requests), the HMI interface gets really 'laggy', reaching up to 30~40s between bit switch command(push of an on-screen button, for example) and actual action. The same behaviour goes for OPC server, although, commands are not as delayed as on the HMI.
I've tried reserving more connection resources for PG communication to no avail. Also tried increasing max scan cycle load from communication (from 20% to 50%), also to no avail.
Scan time didn't change (~35ms) when both were connected.
On CP 343-1 configurations, both ports are set to 'automatic setting'.
I've also observed the same behaviour when monitoring DBs.
Does anyone have any solution for this problem (or, at least, an explanation for why it happens)?
Att.,
Arthur
