Opcua & s7 1214

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"


Anyone have any ideas?
Thank you

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

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