Hello,
this is add on question to this quide.
do you have a simple project to turn on the lights for practice?
Switch and lamp assigned to the hw is described here…
https://help.br-automation.com/#/en/4/gettingstarted/firstprojectio_addhardware.htm
I only use i/o x20cm8281, and plc x20cp1583, are they the same?
Why does every time the status in Automation Studio complete and successfully transfer the lighting project to the PLC an error like this always occur? Even though previously in the Halo Community Safe project, errors like this didn’t occur
From you description is not clear what is your error 
If I see it correct, your CM module doesn’t light up at all, right?
You are missing the I/O supply on the PLC according to your picture.
See B&R Online Help
Also, if you set up ethernet correctly and you can still connect to the PLC after transfer, the Logger should show you that the CM module is missing, which with default settings “Module supervised: ON” leads to service mode
