Restarting a block
RSTART [BL]
This instruction releases the temporary stop, and restarts the sequence from the step where the sequence was stopped in the
specified block.

■Description, range, data type
■Applicable devices
*1 The BL can be index modified.
• This instruction restarts the sequence from the step where the sequence was stopped in the specified block. Operation
HOLD steps (with or without transition check), which have been stopped holding the operation status, restart operation with
the hold status.
• If the block pause/restart bit of the SFC information device is set, the corresponding bit device turns off.
• After the step sequence is restarted, the operation of the PLS instruction and the instructions which is executed only on the
rising edge depends on the status of SM325.
• The RnCPU and RnENCPU with firmware version "12" or later support this instruction. (Use an engineering tool with version "1.015R" or later.)
• The RnPCPU (process) with firmware version "03" or later supports these instructions. (Use an engineering tool with version "1.020W" or later.)
