I found that a folder OPCcap on the path
C:\icm\lan\pg1A\OPCcap (this is on the CCM PG server)
with alot of files like that OPCdata_opc_1101_023729.cap
those files inscrease too much and consume alot of my PG server.
Please let me know what this folder used for and how to turn the log or capture off.
Have you seen this technote?
Thank you David for your reference link.
by the same, I have found a registry key to disable the capture name CaptureMessage under OPC.
