Resetting devices (excluding annunciator)
RST
The status of the device specified by (d) changes as follows when the RST input turns ON.
• Bit devices: Turns the coils and contacts OFF.
• Timers, counters: Sets the current value to 0, and turns coils and contacts OFF.
• Bit specification of word device: Sets the specified bit to 0.
• Word devices, module access devices, index registers: Sets content to 0.

Applicable devices
*1 When using F, refer to
*2 Only the FX5 intelligent function module can use nibble specification of bit devices.
Processing details
• The status of the specified device changes as follows when the execution command turns ON.
• When the execution command is OFF, the device status does not change.
• Function when a word device is specified by the RST instruction is the same as the following circuit.
Precautions
When the RST instruction for a timer or counter is executed by a program containing a jump or by a subroutine program or
interrupt program, the timer or counter is held in a reset state, and the timer or counter may not work normally.
