3.3 Specifications of input/output signals with PLC CPU
3.3.1 List of input/output signals with PLC CPU
The Simple Motion module uses 32 input points and 32 output points for exchanging
data with the PLC CPU.
The input/output signals when the head I/O number of Simple Motion module is set to
"0H" are shown below.
If it is set to other than "0H", change the I/O number according to setting of head I/O
number.
Device X refers to the signals input from the Simple Motion module to the PLC CPU,
and device Y refers to the signals output from the PLC CPU to the Simple Motion
module.
