Any PLC (Ethernet communication) to Raspberry PI using NODE-RED

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?:slight_smile: Codesys has MQTT driver.

I often use Modbus protocol for PLC
Codesys configure
node red configure

I am also looking for the solution to connect any PLC to Python/Node Red do you have any solution ? PLease let me know

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

What is "any PLC"? Omron? Siemens? AB? ETC ETC ETC ETC

Did you try OPCUA? did you try MQTT?

Have you tried anything?
