(1) Ladder execution start signal (R9015.0, Z15.0)
When directed to start ladder program execution, the system
software starts executing the ladder program, turns on this signal,
and keeps it on for the first one scan cycle. Like R9000 and Z0, this
signal indicates the status of ladder execution corresponding to each
ladder execution level. For this reason, this signal is securely turned
on for the first one scan cycle after the start of execution no matter
on what execution level the signal is referenced. This signal is
turned on when:
(a) Ladder execution begins at power turn-on.
(b) The [RUN] soft key on the PMC screen is pressed.
(c) FANUC LADDER-III or a ladder editing package directs the
ladder to start.
Referencing this signal in a ladder program can detect when ladder
execution has begun, making it possible to program preprocessing
related to ladder execution.
CAUTION
Reference this signal only within a ladder program.
Do not reference it from an external system or
program as it indicates the status of ladder execution
separately for each ladder execution level.
