2) When the command contact turns ON, the output M0 turns ON.
3) When the current value of C0 reaches the comparison value D300, the output M0 is reset. "1" is added to
the count value of the process counter C1, and the current value of the counter C0 is reset.
4) The next output M1 turns ON.
5) When the current value of C0 reaches the comparison value D301, the output M1 is reset.
to the count value of the process counter C1, and the current value of the counter C0 is reset.
6) The current value is compared for up to "n (K4)" outputs in the same way (1 ≤ n ≤ 64).
7) When the final process specified by "n" is finished, the execution complete flag M8029 turns ON and
remains ON for one operation cycle.
M8029 is used for many instructions as the instruction execution complete flag. Use M8029 as a contact
just after a corresponding instruction.
8) The program execution returns to the beginning, and outputs are repeated.
Caution
1. When specifying digits of a bit device as
As a device number, specify a multiple of 16 (0, 16, 32, 64 ...).
