<tagname>.STA USINT Channel state Reports a state value for the channel:
1 = no vfield ( < 18Vdc)
2 = off (demand < 0.4mA)
3 = no load/open circuit
4 = on (demand > 0.4mA)
5 = compliance fault (demand cannot be met)
6 = reverse polarity (< -1Vdc)
7 = faulted
Faulted State for Analogue Outputs
An analogue output channel is faulted (the state reports a value of 7) when normal
operation or diagnostics tests have identified a specific fault condition. A single
identified fault condition thus results in a state value of 7.
When the state reports the value 7 then the following 'safe' values are reported by the
other variables:
 Line Fault = TRUE
 Discrepancy = TRUE
 Channel Fault = TRUE
 Voltage = 0mV
 Raw Count = 0mA
Configure Advanced Channel Settings for Analogue Output Channels
The AADvance Workbench provides advanced settings for individual analogue output
channels:
 Specify a shutdown state for an output; this defines how the output will behave
when its parent 9481 or 9482 analogue output module is in a shutdown mode. The
options are Off, Hold Last State and Custom.
 Specify a value for the current output in the shutdown mode, using the same
scaling as the Command Value.
 Specify a threshold for reporting of Discrepancy in parameter Fail-Safe Guard
Band. This is a percentage of 0-20mA demand.
To configure the advanced channel settings do the following:
