25 HIGH-SPEED INPUT/OUTPUT FUNCTION
25.1 High-speed Counter Function
■High-speed pulse input/output module
 of each input is the head input number for high-speed pulse input/output module.
A: Input A phase
B: Input B phase (direction switch input is however employed in the case of 1-phase 1-count [H/W])
P: Input external preset
E: Input external enable
The high-speed pulse input/output module channel numbers are assigned as described below. From nearest
to the CPU module, the high-speed pulse input/output modules are ordered as the first module, second
module, etc.
• High-speed pulse input/output module first module: CH9, CH10
• High-speed pulse input/output module second module: CH11, CH12
• High-speed pulse input/output module third module: CH13, CH14
• High-speed pulse input/output module fourth module: CH15, CH16
Input assignment-wise / maximum frequency for high-speed counters
Input assignment-wise maximum frequency for high-speed counters is as follows.
