■FX5UJ CPU module and high-speed pulse I/O module
Pulse width measurements can be used for a maximum of 12 channels. (CPU module 4CH + high-speed pulse input/output
module 2CH  4 modules)
The input device assignment is as follows. (Fixed for CPU modules)
*1 The number in  is the head input number for each high-speed pulse input/output module.
The table below shows the measurement frequencies.
