Most properly is it a network and/or configuration problem (only). Check the configuration in the Data Layer node “opcuaclient”. The standard port for OPC UA communication is 4840. By using another ones make sure, that the port forwarding to the server is OK (as well for routers between, firewalls etc.). Also, the server must accept/trust the client’s certificate. Check this, but often it is done automatically. @everyone: Feel free to add your ideas and comments, please! ... View more

Hello Axay - what is the status, any news? Nevertheless we have some more hints, if still necessary ... thx to my colleagues! # Please check and change the ECM setting to Auto or Link Layer Reference clock, instead of Freerun: # As mentioned before: Activate in the ctrlX I/O-Eng. the checkbox “Slaves have to reach the master state”. Download it again. That allows to get more detailed diagnosis’ – and the ECM won’t run in OP-Mode at all, if a Slave is in trouble … Then, in the event of the situation, export the EC diagnostics log via IO-Eng in the online state using a right mouse click. # In addition and what Michael_A mentioned, please activate the traces for the PLC and in the event of the situation create another systemreport and provide the PLC and I/O project.  # And last but not least - could you think about to update the system from V2.4 to V2.6?! PS: In the next weeks the new LTS version V2.6.2 will be officially released. Right now the actual early adopter version V2.6.1 is already available in the collaboration room.   ... View more
