27. ZRST (Zone Reset) Instruction in MITSUBISHI PLC - Дастури ZRST (Zone Reset) дар PLC-и MITSUBISHI

Outline
This instruction resets devices located in a zone between two specified devices at one time.
Use this instruction for restarting operation from the beginning after pause or after resetting control data.
Function and operation explanation
1. 16-bit operation (ZRST, ZRSTP)
Same type of devices specified by to are reset at one time.
When the devices specified by and are bit devices
"OFF (reset)" is written to the entire range from the devices specified by to at one time.
Cautions
1) Instructions of pulse operation type are not provided in the FX0S, FX0 or FX0N PLC.
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.
4) Caution for simultaneous instances of the ZRST instruction and the PLS instruction
The ZRST instruction resets the last stage for the PLS instruction and PLF instruction of the applicable
device. In addition, the reset state of T and C is also reset. Accordingly, when the program shown below
is executed, the PLS instruction continuously sets M0 to ON.
5) Caution on simultaneous instances of the ZRST instruction and a counter
The ZRST instruction resets also the last stage and reset state of T and C coils.
Accordingly, if the drive contact of X000 is ON in the following program, the counter executes counting
after the ZRST instruction is executed.
