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 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.
