Pointer [P and I]

4.12.1 Numbers of pointers

The table below shows numbers of pointers (P and I). (Numbers are assigned in decimal.)
When using a pointer for input interrupt, an input number assigned to it cannot be used together with a "high
speed counter" or "speed detection (FNC 56)" which uses the same input range.
