"Error connecting to PLC: Error: Controller requires IP\_ADDR !!!"

My apologies, this is what debug actually states:

"Error connecting to PLC: Error: Controller requires IP\_ADDR !!!"

I don't know about that device, but I am sure if anyone does then the first thing they will want to know is how you are connecting to it from node-red. Which node are you using, for example, and how have you configured it?

Set as MachineinDowntime as boolean and set CoilLength as integer...

That really is of no use to anyone. The devil is in the details.

You haven't answered the questions  
How you are connecting to the device from node-red (serial modbus for example)?  
Which node are you using? Have you installed a contrib node or what?

OK, you need someone who know about that node then, which isn't me.

Thank you, I very much appreciate your replies, I will trace back and see who maintains that node and ask…

I only see Capture-errors.jpg.  
Where is the source of the flow?

You have a bug with node 75b8a235.f4670c.  
There is no such node in the flow source you published.

It is likely the OP has a old (unused) `eth-ip endpoint` config node that is causing that error.

@Industrialogics search ctrl+f for `75b8a235.f4670c` or look in the configuration nodes for an unused node that is not properly setup - delete it and deploy.
