Hi,
have anyone encountered this situation with Siemens Plus Ethernet driver from Kepware?
From time to time, the driver recreates connection with PLC, which takes about 10 seconds, so for that time we can't exchange any data with PLC. We left a ping to the PLC and sometimes we loss packets, but they are not directly correlated with the 'new connection' in OPC. We've also tested in parallel the Ignition Siemens driver and it seems to work better, because it exchange data, when Kepware driver is recreating connection. But maybe Siemens driver from Kepware signals us a problem with network?
