flag M8029 turns ON.

4. How to use this instruction in a relay output type PLC

By providing a "digital switch read input", this instruction can be used in a relay output type PLC.

When the push button switch (X000) is pressed, DSW (FNC 72) instruction executes a series of operations.

Accordingly, with regard to this program, it is not necessary to consider the relay contact life even if Y010 to Y013 are

relay outputs.

While M0 (digital switch read input) is ON, DSW (FNC 72) is driven.

DSW (FNC 72) completes one cycle of operation, and remains driven until the execution complete flag (M8029)
