Can't write Data in PLC

[Jelazzaoui]

Hallo maikakraila, I am using node-red-contrib-opcua client to write and read Data from PLC S7-1512. Reading data works with no problems but when i try to write in the PLC i receive this errors: Error at assert (/home/pi/.node-red/node_modules/node-opcua-assert/dist/index.js:6:21) at new NodeId (/home/pi/.node-red/node_modules/node-opcua-nodeid/src/nodeid.js:86:5) at write_action_input (/home/pi/.node-red/node_modules/node-red-contrib-opcua/opcua/102-opcuaclient.js:722:18) at OpcUaClientNode.processInputMsg [as _inputCallback] (/home/pi/.node-red/node_modules/node-red-contrib-opcua/opcua/102-opcuaclient.js:429:11) at OpcUaClientNode.Node._emitInput (/usr/lib/node_modules/node-red/node_modules/@node-red/runtime/lib/nodes/Node.js:199:18) at Immediate._onImmediate (/usr/lib/node_modules/node-red/node_modules/@node-red/runtime/lib/nodes/Node.js:179:33) at processImmediate (internal/timers.js:439:21)

I wish you could help me to solve this issue. Best regards Jalal

Please check first with UaExpert that nodeId is correct. Is namespace ns=3 ? Or some other index number?

[mikakaraila]

What is in your flow JSON / string that you inject? If you use browseName it requires namespace index this way: // Parse nodeId string, s=1:PST-007-Alarm-Level@Training?SETPOINT

[Jelazzaoui]

I use OPC Scout V10 to get the the namespace, see the screenshot below: Thats what i inject: NodeID;ns=3;s="Baustein_1_DB"."zahl";datatype=Float

[mikakaraila]

It could be something with " characters, just wild idea. Try: ns=3;s=\"Baustein_1_DB\".\"zahl\";datatype=Float

It will need perhaps double \\

[Jelazzaoui]

I tried that, now i dont get errors but i still dont write anything in my PLC

[mikakaraila]

What comes to console? run with option -v node-red -v FLOWFILE.json

[mikakaraila]

Do you inject nodeId as json? Can you change it to item node? Then you inject just numerical value.
