4.3.2 CPU Modules: Functions and Models
1. Functions
1) The CPU Module stores the applications program written in ladder diagram language
and solve the ladder diagram program based on the information from the input section.
The results of solution are output via the output section.
2) Through MEMOBUS port, the CPU Module will run RS-232C communications with ME-
MOBUS masters such as Programming Panels and personal computers.
3) Through MEMOBUS PLUS port, the CPU Module will execute high-speed (1 Mbps) com-
munications with other transmitting equipment such as the GL120, GL130 and personal
computers on MEMOBUS PLUS networks.
2. Models
There are five models of CPU Modules, as shown in the following table. The main differ-
ences among CPU Modules are shown in the following table. For details, refer to section
