Printing a  wiring block diagram
Once you have confi gured a system using Global Confi gurator, you can generate 
and print a simple block diagram of what products to wire to which of the MLC’s 
ports. The diagram includes model names, DIP switch settings for control modules, 
and the type of communication (IR or RS-232) confi gured for each port.

fi le, if desired, and exit Word.

 Saving and uploading the confi guration
This is not an advanced confi guration function, but when you fi nish creating the 
confi guration in Global Confi gurator, you must save the GC project and upload 
the confi guration to one or more MLC units. See chapter 3 of the MLC 226 IP Series 
Setup Guide (shipped with the MLC) for instructions.
