mode.
FORCING FLAGS (FF)
- The 64 forcing flags are used with either
ModBus or ASCII interface. The state of the forcing pages is set
by the ModBus master or the computer communicating over the
ASCII serial connection.
READ / WRITE OPERANDS
PHYSICAL OUTPUTS (OUT)
- Allows the state of one the 8
physical outputs to be set when used as the operand of a output
coil. Physical outputs can be set or cleared by both the PLC and
the sequential program, with the PLC being dominant in the
case of conflict. When used as the operand of a contact it is a bit
flag that follows the state of the output.
LOCAL PLC FLAGS (LF)
- The 64 local PLC flags are used as
internal logic storage in the ladder logic program. They can be
useful for carrying the logic states through multiple rungs. They
can also be used as either an operand for a coil or a contact.
When used as a contact if allows the state of its output coil.
PLC TO SEQUENTIAL PROGRAM FLAGS(PTS
) - These 48 flags
are provided as a means of signaling the sequential motion
program. They can be set and cleared by the PLC, and are read-
only to the sequential program. Normally used to allow the PLC
to provide an asynchronous monitoring function of a condition
or set of conditions, they perform some logic operation or
conditioning and then pass a bit flag to the sequential program.
The sequential program can conditionally branch or call
subroutines according to these bit flags, or monitor them for live
trigger events during motion. This simple construct makes it
much easier to monitor and control events that are
asynchronous with respect to the sequential program.
INDEXER CONTROL FLAGS (ICC
) - This set of flags allows the
PLC to control the axis motion.
Following is a list of these flags and their function.
