FNC186 – DUTY / Timing Pulse Generation

Outline

This instruction generates the timing signal whose one cycle corresponds to the specified number of operation cycles.

1. Instruction format

2. Set data

3. Applicable devices

S: Specify either one among M8330 to M8334.

Explanation of function and operation

1. 16-bit operation (DUTY)

1) The timing clock output destination

is set to ON and OFF with the ON duration for "n1" scans and OFF

duration for "n2" scans.

2) Specify either one among M8330 to M8334 as the timing clock output destination device

3) The counted number of scans is stored among D8330 to D8334 in accordance with the timing clock output

destination device

The counted number of scans stored among D8330 to D8334 is reset when the counted value reaches "n1+n2" or
when the command input (instruction) is set to ON.
