4. Motion Control Instructions 4.6.45. F_Trig Explanation of the instruction: When EN is On and CLK turns on -> off, Q outputs the high level for one scan cycle. F_Trig is used to trigger via falling edge of CLK bit to make Q bit generate the high level for one scan cycle. Explanation of input and output parameter of the instruction Program example As I0=On and M0 turns on -> off via the trigger of the falling edge, "F_Trig" instruction is executed; "Q0" outputs the pulse once and the length of the pulse is one scan cycle.
