ISG
The Initial Stage instruction is normally used
as the first segment of an RLL
PLUS
Stage
program. Multiple Initial Stages are allowed in
a program. They will be active when the CPU
enters the Run mode allowing for a starting
point in the program. Initial Stages are also
activated by transitional logic, a jump or a set
stage executed from an active stage.

Stage S 0--377
NOTE:
If the ISG is within the retentive range for stages, the ISG will remain in the
state it was in before power down and will NOT turn itself on during the first scan.

S
The Jump instruction allows the program to
transition from an active stage containing
the jump instruction to another stage
(specified in the instruction). The jump
occurs when the input logic is true. The
active stage containing the Jump will
deactivate 1 scan later.

NOTE: The F1--130 CPU does not have the Not Jump instruction (as does other
PLC families). You may still achieve the same result by using the Jump instruction,
while inverting the sense of contact logic that activates that instruction.
