Opc ua client

Hello everyone ! I communicate successful AXC F 2152 and siemens s7-1200 via OPC client ( my laptop ) on Node-red, AXC F 2152 and s7-1200 are OPC server

If i have SD card and install Node-red internal on AXC F 2152 ( docker ) , which device is OPC client ? And if i unplug the LAN cable from my laptop ? Will my PLCnext still communicate with siemens without laptop ?

Thanks

    The OPC UA client will be the software (node-red?) that is running in the OCI container. If that is on an AXC F 2152, then that device will be running both an OPC UA client (in a container) and an OPC UA server.

    The other question is about how Node-red works. This question is answered on many Node-red forums, e.g. here:

    Thank Mr .Martin !

    If i run both opc client and server in PLCnext , will i still use Uaexpert on Laptop normally ? Are Container on PLCnext affected ? Because i saw Uaexpert is the sowftware of Laptop , not image of container

    Thanks

    will i still use Uaexpert on Laptop normally ?

    Yes, because the PLCnext Control device is still running an OPC UA server, you can still use UaExpert from a laptop to connect to the OPC UA server.

    Are Container on PLCnext affected ?

    No, a connection between UaExpert and the OPC UA server on the PLCnext Control device will have absolutely no effect on any containers running on that device.

    I hope this answers the questions.
