ISG
The Initial Staget instruction is normally
used as the first segment of an RLL
PLUS
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.

Stage S 0–377
Initial Stages are also activated by transitional logic, a jump or a set stage executed
from an active stage.

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.

The Not Jump instruction allows the
program to transition from an active stage
which contains the jump instruction to
another which is specified in the instruction.
The jump will occur when the input logic is
off. The active stage that contains the Not
Jump will be deactivated 1 scan after the
Not Jump instruction is executed.

In the following example, only stage ISG0 will be active when program execution.
begins. When X1 is on, program execution will jump from Initial Stage 0 to Stage 1.
