D PC Link Module: Mount to CPU Rack
D MEMOBUS Module (RS-232/RS-422): Mount to any Rack of the local channel
D 4-axis Motion Module: Mount to CPU Rack
4) I/O Modules can be used within the maximum number of I/O points shown in the following
table.
Item GL120 (CPU20, CPU21, CPU10) GL130 (CPU30 and CPU35)
Number of
digital I/O
points
1,024 points max. (1 point = 1 bit) 4,096 points max. (1 point = 1 bit)
Number of I/O
registers
512 registers max. (1 register = 16 bits)
Number of
remote I/O
points
The number of I/O points and registers at each station must meet the following
conditions:
1) (No. of digital input points ÷ 8) + (No. of input registers x 2) ≤ 512 (bytes)
2) (No. of digital output points ÷ 8) + (No. of output registers x 2) ≤ 512 (bytes)
