ONE-SHOT FLAGS (ONS)
- Stores the output state of the one of
the 16 associated one-shot operations available for use in the
ladder-logic program.
TIMER FLAGS (TMR)
- Holds the output state of one of the
associated 16 timer operations available.
COUNTER FLAGS (CTR)
- Holds the output state of one of the
associated 16 counter operations available.
SEQUENTIAL PROGRAM TO PLC FLAGS (STP
) - This set of
general purpose bit flags is a series of 32 bits that are read or
write in the sequential program and read only in the PLC. These
bits are normally used to allow the sequential program to signal
the PLC. These bits can then be used in the ladder logic program
to control I/O or logic in the PLC program.
SPECIAL PURPOSE FLAGS (SPL)
- These bit flags are provided
with fixed logical functions
First Scan (SPL001)
- This bit flag is true on the first PLC scan
after power-up, it is false otherwise.
Logic One (SPL002)
- This bit flag in always true
Logic Zero (SPL003)
- This bit flag is always false
P2 DSUB Pin 6 <--> Pin 9 (SPL004)
- This bit is true only
when pins 6 and 9 of DSUB P2 are shorted
INDEXER STATUS FLAGS (IS)
- Indexer status bit flags are
provided to allow the PLC access to the controller operating and
motion status.
Auto-phasing complete (IS001)
- This bit flag is true if
phasing complete, otherwise it is false.
Fault (IS002)
- This bit flag is true if the drive is faulted
otherwise it is false.
Fatal Fault (IS003)
- This bit flag is true if the drive has a fatal
fault, otherwise it is false.
Axis Home Position Defined (IS004)
- This bit flag is true if
the homing instruction was executed to completion in the
sequential program.
Motion-in-Progress (IS005)
- This bit flag is true if the axis is
currently executing a move.
Axis in Position (IS006)
- This bit flag is true if the encoder
position is within the preset in-position band, otherwise it is false.
