• The execution of the corresponding block is restarted from the step where it had stopped when the "block STOP/RESTART
bit" is turned OFF in the sequence program, SFC program or peripheral device. An "operation HOLD status" step (with
transition check or without transition check) which has been stopped will be restarted with the operation HOLD status in
effect. A coil output HOLD step cannot be restarted after being stopped as it is deactivated at that time.
• When a block STOP is canceled, the PLS or
selection at block STOP (SM325) is turned ON, the PLS or
• When the SFC control "block STOP" instruction (PAUSE BLm) is executed, the block in question is stopped, and the block

stopped, the block in question is restarted, and the block STOP/RESTART bit switches OFF.
• Stopping of program processing by a block STOP/RESTART bit being switched ON, or by a block STOP
instruction, applies only to the specified block.
• Even if a block stop is executed for the START destination block, the START source block will not be
