OFS notification rate overrun
Dear community !
The OFS product is somewhere in the gap between PLC and SCADA forums, but i hope it fits better here as an integration tool.
I've got messages "notification rate overrun" in diagnostic window (see the screenshot attached) and can't find the proper description in supplied manual.
The issue appears several times a day and prevents writing from OPC client to PLC tags. My guessing is that OPC client is overloaded and can't consume OFS notification of tag changes, but it requires confirmation.
