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.
