Hi Friends,
Could you please share the step by step procedure to configure Codesys PLC (through Ethernet connection to Raspberry PI) using Node-red.
Does codesys have a built in OPCUA server? Then install node-red-contrib-iiot-opcua
Does it do modbus? The install the modbus nodes and give it a try.
Thanks for the response.
Yes codesys has OPC UA server and the same(PC) is connected to Raspberry PI through Ethernet. hence "install node-red-contrib-iiot-opcua" needs to be installed on Raspberry PI.
hope my understanding is correct.
Do you have any document which explain step by step procedure to configure codesys OPCUA using "install node-red-contrib-iiot-opcua"
Maybe MQTT is better solution?
Codesys has MQTT driver.
I often use Modbus protocol for PLC

Did you look at the other posts in the thread that suggest ways this may be done?
