2PH
counting
input
When SM100–SM104 are set to OFF, counters C251–C255 are
automatically incremented and decremented according to 2PH input.
You can know the current counting direction of the corresponding
counter through SM251–SM255. The counter counts up when the SM
element is OFF, or counts down when it is ON. The counting direction is
defined as follows:
A

input
When SM100–SM104 are set to ON, counters C251–C255 automatically
perform quadruple frequency counting according to 2PH input. You can
know the current counting direction of the corresponding counter
through SM251–SM255. The counter counts up when the SM element is
OFF, or counts down when it is ON. The counting direction is defined as
follows:
