I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA.
Occasionally, the HMI stops displaying data, and looks as if there is no connection.
If the HMI stops, the only way to make it work again is to restart the PLC.
Restarting HMI has no effect.
When the PLC is restarted, HMI starts working normally again.
Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart.
Thanks
