Details
This relay is on when an SFC program has been
registered, and is off when no program is registered.
• The same value as in SM1100 is set as the initial
value. (This relay turns on when an SFC program
is registered.)
• This relay is turned off to stop SFC program
execution.
• This relay is turned on to resume the SFC program
execution.
In the SFC setting of the PLC parameter dialog box,
Initial start is set for the SFC program start mode.
• At initial start: OFF
• At continue start: ON
Set whether to enable or disable continuous
transition for the blocks where "continuous transition
bit" of the SFC information device is not set.
• This relay is off during operation in the continuous
transition mode or during continuous transition,
and is on while continuous transition is not
performed.
• This relay is always on while the CPU module is
operating not in the continuous transition mode.
The relay turns on when measurement by the step
transition monitoring timer is started. The step
transition monitoring timer is reset when the relay
turns off.
Selects the operation output when block stop is
executed.
• On: Retains the on or off status of the coil used in
the operation output of the step, which was being
executed at the time of block stop.
• Off::Turns off all the coil outputs. (Operation output
by the SET instruction is retained regardless of the
on/off status of SM1196.)
