Faulted State for Digital Outputs

A digital 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



Current = 0mA

Configure Advanced Channel Settings for Digital Outputs

The AADvance Workbench provides advanced settings for individual digital output

channels:



You can specify a shutdown state for an output; this defines how the output will
behave when its parent 9451 digital output module is in a shutdown mode.



You can disable the line test feature for an output; this disables detection of a no-
load condition.

To configure the advanced channel settings do the following:

1) Select the slot with the digital output module.



The module status variable name <tagname> that you assigned appears in the
Variable field.

2) Select the channel to configure and click the Advanced tab.



The 9451 Advanced Channel Settings dialog box opens.

3) Put a tick in the box labelled Use Custom Advanced Channel Settings.
4) Put a tick in the box beside the Shutdown State field or the Disable Line Test

field.

5) Choose the advanced channel settings from the drop down options.
