Assignment for high-speed counters
Input assignment for high-speed counters
Assignment for input devices of high-speed counters is set by parameters.
Assignment is determined according to functions set for each channels by parameter.
When using internal clock, assignment is same as 1-phase, 1-count (S/W) and A phase is not used.
Input assignment of high-speed counters is as follows.
