The status does not detect errors on the read/write nodes...
By using catch and a function, I'll manage to do what I need: a status bit for all the communication nodes.
You said that it shows connecting, which means that it is not working.
I was referring to the status node I added for testing purposes.
Once again, a message appears in the status node when a read node is used.
If the read node is disabled and a write operation is performed, no error is reported in the status node; however, the error is reported in the Catch node.
But presumably the status of the write node is showing that it is not working.
