RST Box Function
Reset Coil (Unlatch)
Category: Bit and Latch Box Functions
Behavior
When the left condition is ON, stores OFF in an M bit or a P bit configured as an output. Use a ladder RESET coil, rather than box-function RST, to initialize a timer or counter.
Syntax and Arguments
Syntax: RST M0
- 1st = target: M bit or P bit configured as an output
Behavior Example
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | M0=ON | RST M0 | M0=OFF |
Cautions
- Use an M bit or a P bit configured as an output. The stored state remains after the condition turns OFF.
- Use a ladder RESET coil, rather than box-function RST, to initialize a timer or counter current value.
