Related instructions
1. RST
As an independent reset instruction for devices, RST instruction can be used for bit devices (Y, M and S) and
word devices (T, C, D and R).
2. FMOV
FMOV instruction is provided to write a constant (example: K0) at one time. By using this instruction, "0" can
be written to word devices (KnY, KnM, KnS, T, C, D and R) at one time.
Cautions
1) The FX0, FX0S or FX0N PLC does not support the instructions of pulse operation type.
To execute pulse operation, make the instruction execution condition pulse type.
2) Specify same type of devices in the devices specified by and . The device number of the device
specified by should be smaller than or equal to the device number of the device specified by .
If the device number of the device specified by is larger than the device number of the device
specified by , only one device specified by is reset.
3) When specifying the high-speed counter, ZRST instruction is handled as the 16-bit type, but 32-bit
counters can be specified in and .
However, it is not possible to specify a 16-bit counter in the device specified by and specify a 32-bit
counter in the device specified by ; and should be a same type.
Program example
