DRAW.NO.
(2) Ladder stop signal (R9015.1, Z15.1)
When directed to stop ladder program execution, the system
software turns off this signal and keeps it off for the last one scan
before stopping ladder program execution. 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
off for the last one scan before the stop of execution no matter on
what execution level the signal is referenced. This signal is turned
off when:
(a) The [EXIT] soft key on the PMC screen is pressed.
(b) FANUC LADDER-III or a ladder editing package directs the
ladder to stop.
(c) On the PMC DATA I/O screen, the ladder program is loaded
to the PMC.
(d) FANUC LADDER-III or a ladder editing package stores the
ladder program to the PMC.
Referencing this signal in a ladder program can detect when ladder
execution stops, making it possible to program post processing
related to ladder execution (that is, preprocessing for ladder
execution stop). Before the ladder is stopped, for example, it is
possible to put signals in a proper state for safety purposes.
CAUTION
1 Reference this signal only within the 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.
2 If the power is turned off or a CNC system alarm
occurs, ladder execution and I/O signal transfer are
immediately stopped for safety purposes. In this
case, therefore, this signal cannot be used.
(3) Ladder execution status signal (R9091.2, R9091.3, R9091.4, Z91.2,
Z91.3, Z91.4)
Referencing this signal from an external system or program, such as
the network board, C language executor program, FOCAS2
Ethernet, or HSSB library, can detect the execution status of the
ladder program.
