Pausing And Restarting A Block - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Pausing and restarting a block

Pausing a block
The specified block in the SFC program being executed can be paused by either of the following methods.
Item
SFC control instruction
SFC information device
Operation when the block is paused or restart depends on the combination of the SM325 (Output mode at block stop) status,
block stop mode bit setting of the SFC information device, and step hold status. ( Page 133 Operation when the block is
paused or restarted)
Restarting a block
The paused block in the SFC program can be restarted by either of the following methods.
Item
SFC control instruction
SFC information device
Operation when the block is paused or restart depends on the combination of the SM325 (Output mode at block stop) status,
block stop mode bit setting of the SFC information device, and step hold status. ( Page 133 Operation when the block is
paused or restarted)
Method
Pause the block specified by the PAUSE [BL] (Pausing
a block) instruction used in the action of the SFC
program or in another sequence program.
Pause the specified block by turning on the block
PAUSE/RESTART bit set to each block.
Method
Restart the block specified by the RSTART [BL]
(Restarting a block) instruction used in the action of
blocks other than the paused block in the SFC program
or in another sequence program.
Restart the specified block by turning off the block
PAUSE/RESTART bit set to each block.
Remarks
This method is effective to clear the
error by temporarily stopping the
machine and operating it manually.
This method is effective for
debugging and test operation
because blocks can be paused
even from external devices.
Remarks
This method is effective in operating
the machine automatically again
after it is stopped temporarily and
operated manually.
This method is effective for
debugging (in units of blocks) and
test operation because blocks can
be restarted even from external
devices.
