no connection whit OPC sever (OPCServer 6002 Failed to subscribe on 172.16.84.152)
I have problem to connect CPU AC800 PM891 whit OPC server AE
no problem whit OPC Data.
settings are ok was ranning well up to a certain date.
I attach files log
"Max Number of AE Subscribers" setting on CPU (0) at default value (1) and you have redundant OPC servers (or a Panel 800 subscribing as well)?
Increase, download and try connecting again!
Sometimes, in the past, stale/obsolete subscriptions could be left in CPU. If this happen, CPU must be reset, or an even larger "Max no..." must be downloaded. Search for bulletins describing this problem.
