i have a third party Gateway that acquires data from various RTU's in different remote locations and, the gateway and the rtu speaks modbus language, for the realtime data to be visible in PI Server , we use Matrikon OPC Sacda Modbus along with the PI OPC interface:
the Challenge we are having is the The OPC server hangs at will. therfore we can [mods note: cannot?] see any trending during those hanging periods.
what we did was to use a script to stop/restart the server 3 times in a day. and the hanging was reduced. but we needed a total solution not by using a script to stop the service (the server should run seemlessly).
Also an upgrade has been done to the Scada Modbus server but the situation still remains thesame so we are still using the script.
can any one Suggest a solution to this Problem?
