Plf | Mitsubishi Electronics 700 Series, FR-A700 manual

Sequence Instructions

PLF

(1)Turns the specified device on one scan when the PLF command turns from ON to OFF, and turns it off except when the PLF command turns from ON to OFF.

When there is one PLF instruction for the device specified at D during one scan, the specified device turns on for one scan.

Do not execute the PLF instruction for the same device more than once during one scan.

1scan 1 scan

(2)If the status is switched to STOP and switched to RUN again after execution of the PLF instruction, the PLF instruction is not executed.

Program Examples
