2.1 Overview of the MEMOCON GL120 and GL130
This section outlines the MEMOCON GL120 and GL130.
1) The MEMOCON GL120 (abbreviated GL120) and MEMOCON GL130 (abbreviated
GL130) are programmable controllers (PLCs) developed to succeed the MEMOCON-
SC GL60 Series. The MEMOCON-SC GL60 Series has been well received and is very
popular for key controllers in FA systems. The GL120 and GL130 are mid- to large-ca-
pacity programmable controllers. They provide greater compactness, higher quality, and
higher performance while retaining the functions of the GL60 Series. The GL120 and
GL130 have program memory capacity of 8K words, 16K words, 32K words, and 40K
words, making the GL120 a mid-capacity controller and the GL130 a large-capacity con-
troller.
2) The GL120 and GL130 can be used as high-speed machine controllers or as key control-
lers for various automatic devices, and can be applied to the following control:
D Sequence control D Motion control D Process control D Computational control
3) The difference between the GL120 and GL130 lies in the CPU Module that is used. A
PLC using the CPU20 CPU Module is a GL120, while a PLC using a CPU30 CPU Module
is a GL130. All devices other than the CPU Module can be used in both PLCs.
