3.3.1

List of input/output signals with CPU module

The LD75 uses 32 input points and 32 output points for exchanging data with the CPU module.
The input/output signals when theLD75 is mounted to the CPU module and is assigned to the I/O numbers X/Y00 to
X/Y1F are shown below. Device X refers to the signals input from the LD75 to the CPU module, and device Y refers to
the signals output from the CPU module to the LD75.
