ALT (FNC 66)
Operation:
T h e s t a t u s o f th e d es t in a t io n d e v ic e ( D ) is
a l t e r n a t e d o n e v e r y o p e r a t i o n o f t h e A LT
instruction.
a l t e r n a t e d o n e v e r y o p e r a t i o n o f t h e A LT
instruction.
This means the status of each bit device will flip-
flop between ON and OFF. This will occur on every
program scan unless a pulse modifier or a program
interlock is used.
The ALT instruction is ideal for switching between
two modes of operation e.g. start and stop, on and
flop between ON and OFF. This will occur on every
program scan unless a pulse modifier or a program
interlock is used.
The ALT instruction is ideal for switching between
two modes of operation e.g. start and stop, on and
off etc.
5.7.8
RAMP (FNC 67)
Operation:
The RAMP instruction varies a current value (D)
between the data limits set by the user (S1and S2).
The ‘journey’ between these extreme limits takes n
program scans. The current scan number is stored
in device D+1. Once the current value of D equals
the set value of S2the execution complete flag
M8029 is set ON.
The RAMP instruction can vary both increasing
and decreasing differences between S1and S2.
