MOD 30ML Data Base Reference
BUILT-IN ANALOG OUTPUT BLOCK
21 Restart preset value (PRESET)........................................................................................ CWR
A floating point value, in engineering units, used as the restart output when preset
is selected.
22
Track status (TRKSTAT) ...................................................................................................– WR
Track status is set to track whenever the path from the input to the result is broken.
This occurs when the data quality is bad, or the I/O lock is locked, or when the
mode is manual.
NO TRACK 0 Data quality is good, I/O lock is unlocked and mode is auto.
TRACK 1 Data quality is bad, I/O lock is locked or mode is manual.
23
Track status data quality (TRKQ) ....................................................................................– WR
This data quality field is not changed by any internal logic and will always be
GOOD unless written otherwise.
24
Initial Scaled result (RSC) ................................................................................................ CWR
The initial scaled result is the input value in engineering units used when the block
is initially downloaded. This value is overwritten when the block first executes.
During execution this value is normalized, and action is applied; it is then
converted to a signal range and written to the result. The scaled result is writeable
only in manual, when the I/O is locked, or when the instrument state is not run.
26
Maximum Output (MAXOUT)............................................................................................ – – R
The maximum milliampere output (nominally 54 mA) that can be obtained from the
built-in circuit.
40
Input (INPUT) ..................................................................................................................... CWR
The block input is a floating-point value that can be obtained from either a local or
remote source.
Local An input value in engineering units can be configured and is
displayed in the
Local field. The local input can be written when the
block is in auto.
Remote Connection of a floating point LSP to the block input overrides any
existing local input and provides the remote input type. The
Remote
field shows the connection path data. The input value cannot be
written when the source is remote; the value is readable.
50
Result (R) ........................................................................................................................... – – R
This is the actual instrument output in milliamps.
51
Result Quality (RQ) ...........................................................................................................– WR
The result quality is set BAD when the input status is bad and bad inputs are not
accepted, or if the restart value cannot be read after a warm start. Any write to the
result causes the result quality to be set GOOD. The result quality is writeable in
manual, when the I/O is locked, or the instrument state is not run.
