Hi Hendrik,
no need to include Modbus driver in your case. You will implement your own inside the REXLANG block.

Thanks, not sure if I need to add the Modbus drivers to the EXEC?

Hi Hendrik,
the Modbus driver of the REX Control System does not support ASCII format, sorry.

You can still implement arbitrary communication protocol using the REXLANG programmable function block. Here is an example on UDP communication and here is one on TCP communication.

Hope this helps,
Jaroslav

I have a 3rd party controller which uses ASCII syntax commands over Ethernet (Modbus - TCP/UDP) My question is how do I send ASCII syntax commands from Rex target device to 3rd party controller and vice versa?
