T9K_AO_COMPACT and T9K_AO_FULL (Analogue Outputs)
The data structures for analogue outputs (T9K_AO_COMPACT and
T9K_AO_FULL) provide the elements detailed in the tables.
Table 15: T9K_AO_COMPACT Structure for Analogue Outputs
Identifier Type Description Remarks
<tagname>.CV REAL Command Value Demanded current. A scaled, floating-point value
representing the analogue loop current.
Default scaling factor is 0 to 100% representing 4
to 20mA
<tagname>.LF BOOL Line fault TRUE: no field supply is present, no load is
connected, the commanded output current
cannot be met, the wiring polarity is reversed or
channel fault (states 1,3,5,6,7)
<tagname>.DIS BOOL Discrepancy TRUE: Measured current and commanded
current differ by more than the Fail-Safe Guard
Band.
Table 16: T9K_AO_FULL Structure for Analogue Outputs
Identifier Type Description Remarks
<tagname>.CV REAL Command Value Demanded current. A scaled, floating-point value
representing the analogue loop current.
Default scaling factor is 0 to 100% representing 4
to 20mA
<tagname>.LF BOOL Line fault TRUE: no field supply is present, no load is
connected, the commanded output current
cannot be met, the wiring polarity is reversed or
channel fault (states 1,3,5,6,7)
<tagname>.DIS BOOL Discrepancy TRUE: Measured current and commanded
current differ by more than the Fail-Safe Guard
Band.
<tagname>.CF BOOL Channel fault TRUE: module diagnostics detect a fault in the
channel electronics or firmware (state = 7)
<tagname>.V INT Voltage Reports the channel voltage at the output
terminals, in units of millivolts and with an
accuracy of ± 500mV.
<tagname>.CNT INT Raw count Reports the current for the channel in raw units
scaled 256 per mA (from 0mA = 0 to 24mA =
6144)
