In a multi function counter block detail window, one cam switch block ("Cam_Switch") linked to a counter timer block is
arranged across the fourth and fifth sections. However, no cam switch block is arranged in a 16-bit multi function counter

output.

*1 "Count Value" in the counter timer block and the cam switch block is linked automatically and the link cannot be deleted.
*2 The valid range is determined by the type of the multi function counter block arranged in the hardware logic outline window.
