5.12 SFC parameters
The SFC parameters include "task parameters" used to control the tasks (normal task,
event task, NMI task) and "program parameters" set for each SFC program.
5.12.1 Task parameters
No. Item Setting range Initial value Remarks
1
Number of
continuous
shift lines
Normal task 1 to 30 3
2 Interrupt setting
Set either "Event task" or
"NMI task" for external
interrupt input (I0 to I15).
Event task
These parameters are retrieved at the
rising edge of the PLC READY signal
(M2000). Then control is executed.
Turn the PLC READY signal (M2000)
OFF before setting or changing those
parameters.
5.12.2 Program parameters
The following parameters are set for each SFC program.

Event task
* When the event task is set, set the event to be
validated.
Be sure to set one of following (1 to 3).
1. Constant cycle
0.8ms, 1.7ms, 3.5ms, 7.1ms or 14.2ms or none
2. External interrupt (selection from the events set
for event task)
It is possible to set the multiple events from I0 to
I15.
3. PLC interrupt
It is possible to set the multiple events for 1 to 3
shown above.
The same event may be shared by multiple SFC
programs.

NMI task
* When the NMI task is set, set the interrupt to be
validated.
1. External interrupt (select from the events set for
event task)
It is possible to set the multiple events from I0 to
I15.
Normal task
3
Number of continuous
shift lines
1 to 10
* Set the number of continuous shift lines set for the
program set in the event task or NHI task.

4 END operation
End/continue
* Set the operation mode of END step for the
program set in the event task or NMI task.

is executed.
Turn the PLC READY
signal (M2000) OFF
before setting or
changing those
parameters.
