Hello, im trying to use the node-red-contrib-opcua to set up a opc ua server to simply send a value as a variable to the serven and then read that value out. Sadly it doesnt seem to work at all. Has someone expirience with that contrib and can help me?
This is what ive tried:
```auto
[{"id":"51f3cd2b.9327a4","type":"Com-Server","z":"dee6185f.a7fdc8","name":"","topic":"","host":"","port":8000,"format":"string","encoding":"utf8","delimiter":"","sendDelimiter":false,"setuart":false,"configport":9094,"baudrate":3,"parity":0,"databits":8,"stopbits":1,"permupdate":false,"manualConfig":false,"device":null,"x":1100,"y":540,"wires":[[]]}]
```
