Use the High-Speed Counter and Programmable Limit Switch Chapter 8
The main high-speed counters support 10 types of operation mode and the sub
high-speed counters support 5 types (mode 0, 2, 4, 6, 8). If the main high-speed
counter is set to mode 1, 3, 5, 7 or 9, then the resub high-speed counter will be
disabled.
