Opcua & s7 1214

Hi,
I should connect S7-1214 plc to via node-red-contribut-opcua version 0.2.101.
The version of node-red is 1.2.9 on W7 64 operating system.
OPC UA does not connect, gives error message: “invalid endpoint”.
The plc connects correctly via opcua through Unified OPCUA-Expert software.

In the system I also see the message "Local own certificate is not used"

[{"id":"a88acd86.a387c","type":"OpcUa-Client","z":"aeff3edd.e5f7a","g":"a48d4dbe.39bf5","endpoint":"5f2c327f.782d8c","action":"read","deadbandtype":"a","deadbandvalue":1,"time":10,"timeUnit":"s","certificate":"n","localfile":"","localkeyfile":"","securitymode":"None","securitypolicy":"None","name":"","x":130,"y":190,"wires":[["8d6efec5.f78aa"]]},{"id":"5f2c327f.782d8c","type":"OpcUa-Endpoint","endpoint":"opc.tcp://192.168.10.111:4840","secpol":"None","secmode":"None","login":false}]

Anyone have any ideas?
Thank you
R.

Do you have an OPC-UA server on your PLC?

hi,
yes on the PLC there is the OPC-UA server activated.
This is possible by upgrading the CPU firmware.
