Matrikon OPC Server freezes as soon as the data subscriptions happens from 800xAi
Scenario: Analyzer data transfer to 800xA through Matrikon tunneler
As soon as 800xA connects to the OPC Server, it freezes after some time. If the service is disabled in service structure, Matrikon explorer conntinuously updating the value from opc server.
Any solutions please?
Do you get any system events in the [Workplace Structure]Web System Workplace:System Event List?
The OPC DA Connector is a reliable OPC client; it works with a multitude of OPC servers - I agree with Rob, you should speak with Matrikon and maybe also with the vendor of the OPC server about this.
OPC can be complex, just because one (1) client is able to read data it does not automatically mean the problem is in the other client that does not receive any data. An OPC server must be able to handle all clients simultaneously - some servers have issues that may only be seen in some of the clients.
The OPC framework of 800xA contain a lot of logging and statistics functions that may reveal clues to what the actual problem is. Your regional ABB support center shall be able to assist you with creating and escalating a support case for you.
