What is the use of Mitsubishi plc rising edge in programming?

Very useful, applied to places where the signal only needs to be received once

For example, when using the counter C

As shown in the figure, after X0 is turned on, C0 will count to 50 in an instant. After using the rising edge, only X0 can be turned on and off 50 times to count up to 50.

For example, the mov instruction, using the rising edge mov and not using is very different.

As shown in the figure, after the x1 turns on the mov, the value in the D100 is always equal to 10, and the D100 cannot be modified.

After X2 turns on the rising edge mov, the value inside D200 can be modified.
