Linux Based Wago Controllers offer an REST:API to read/write different settings of WBM. you’ll find the API description on your contoller at: http://IP/openapi/wda.openapi.html#section/REST-API-Overview

you will find two code snippets for Nodered and Python as exampels to interact with the API on the Git hub Repo:

This is very cool. Is there a way to R/W to the KBUS as well?

Hello,

Is there a way to configure the IO on the 751-9402 (CC100) via WDx? (ex. set the DIO and AIO?)

Also is it possible to R/W to the IO?

Hello, yes I was able to do it using node-red.
do you need me to resume what I have done ?

Thanks! I see the device model information here: WAGO Device Model - 751-9402 | WAGO Download Center

I also found an example flow to do this with Node-RED. Once I have the hardware, I’ll try it out and share the flows

Hello Mike, Icard,

I also very interested to reach IO of 751-9402 via Node-RED. Could you please share your flows and experiences? I will use it with my customer in Turkey. Thx!

Yes, I did not create these flows, but found them helpful in understanding how to access the IO.

  • You will need to go into each HTTP node, and add your PLC’s login credentials.
  • To set outputs, you will need to set the access mode to “control mode”
  • There is also a nice UI.

Thanks to whoever made this example :slight_smile:

I think I have the same demo. I think we should have something to make the HTTP part easier (Like only having one server declaration and using the same with an layer on top for each request.)

Thanks for all answers guys. I agree that we need to have easy configuration for http, https part in node-red and codesys 3.5 as well.
