EASY4 MODBUS RTU write Singel coil example needed

[AlesH]

Hi, I'm straggling with Modbus RTU. I have set all communication data between Master and slave but I don't understand a logic of writing of a single coil and MU acyclic request module. How I need to write a program.
I'm asking Eaton or other forum expert to provide me an example.

Thank you in advance Ales
