Function
PAUSE STEP
SP, jSP
(211)
SP N
Changes a step or subchart from execute to
pause status. To pause a subchart, specify the
subchart dummy step for N
1
. Actions with
S-type action qualifiers will continue to be
executed.
N:

RESTART STEP
SR, jSR
(212)
SR N
Changes step N from pause to execute status.
To restart a subchart, specify the subchart
dummy step for N.
N:
#
429
END STEP
SF, jSF
(213)
SF N
Changes step N from execute or pause to halt
status. To halt a subchart, specify the subchart
dummy step for N. Actions with S-type action
qualifiers will continue to be executed.
N:
#
430
DEACTIVATE STEP
SE, jSE
(214)
SE N
Changes step N from active (execute, pause,
or halt) to inactive status. To deactivate a
subchart, specify the subchart dummy step for
N. Actions with S-type action qualifiers and
those with action qualifier with the H option will
not be reset.
N:
#
431
RESET STEP
SOFF, jSOFF
(215)
SOFF N
Resets step N (regardless of its status) to
inactive status. It also resets actions with
action qualifiers S, SD, DS, and SL. To reset a
subchart, specify the subchart dummy step for
N.

RESET TIMER/COUNTER
CNR, jCNR
(236)
CNR D
1
D
2
When D
1
and D
2
are timer or counter
numbers, CNR(236) resets the PV of timers
from D
1
through D
2
without starting the timers
or counters. PVs for TIM, TIMH(015), CNT,
and TCNT(123) are reset to the SV, while PVs
for CNTR(012) and TTIM(120) are reset to
zero. TIML(121) and MTIM(122) timers cannot
be reset with CNR(236). If only one timer or
counter needs to be reset, that timer or
counter number can be entered alone. It is not
necessary to enter both D
1
and D
2
.
When D
1
and D
2
are addresses in a data
area, CNR(236) sets the content of words D
1
through D
2
to zero.
D
1
must be less than or equal to D
2
.
