Configuring the SIMOCODE pro V PN OPC UA server - Requirements
Activating the OPC UA server
In the default setting, the OPC UA server is not active. For activation, the parameter
"PROFINET Parameters → OPC UA Server Activated" must be set.
Note
Restarting the communication interface
Each change to the "Activate OPC UA server" parameter requires that the communication
interface be restarted.
A new start of the communication interface interrupts all Ethernet and PROFINET links and
reestablishes them afterward.
Note
