6.4.5 Connections between AC I/O Modules
1) Whenever two or more GL120 or GL130 PLCs are used in a system, connect them as
shown in the following figures to exchange signals between the AC I/O Modules of the
GL120 or GL130. Use AC Input Modules and AC Output Modules with the same volt-
age ratings.

2) Using GL120 or GL130 in combination with Existing MEMOCON PLCs
When signals are exchanged between existing MEMOCON PLCs and a GL120 or
GL130 PLC through an AC Input Module and an AC Output Module, the following items
must be considered. Contact your Yaskawa representative.
