OPC AE connection error
In one of the controllers everytime we connect the OPC Alarm and Server connection in the OPC server configuration the smiley is good. But after sometime there is error. This is happening only for one controller in both redundant connectivity servers. What could be the problem.
Note: This controller has issue with redundant connection.
Please enusure thefollowing:
1.RNRP monitoring is showing (up,up) for both the networks with no drops in between.
2.Ping the controller & check the TTL is less than ms
3.check in the controller settings "OPC AE subcriptions"for that controller should be 2,If not make the settings 2 & then down load the controller.
If this not resolves your issue please send your controller & OPC log.
