Everything is chinese the first time :-), don't worry.

Can you show me the configuration of the Relay 4 Node within Node-RED?
Also open your EVOKE configuration bij entering in your case 192.168.1.7, and show the configuration of your relay 4.

@zdenek_jotio Success!!
I've changed your inject node to "1" instead of "1_01" and it's worked.
Finally getting somewhere.... Changing the nodes is working on all examples now
Brilliant, thanks for the direction

Hello @lessmann,
the limit of how many devices can be connected to one RS485 line comes from the RS485 transceiver (the chip on the RS485 output) and on our PLCs it is 32. But be aware, that this is just a theoretical limit and the real limit depends on the current situation.

Second limit of the RS485 is the speed of the communication. Since RS485 is a half-duplex type of communication (master can speak only to one slave at a time), the more devices you have the lower speed of updates you will have.

If you have PLC with more RS485 ports, you can split the extensions into groups.

Best regards,
Martin
