4.3. I/O Status LEDs

There are 40 output channel status indicators on the module front panel, one for each field output.

These indicators are controlled by the FPU. The FPU receives data from each of the module slices.

The FPU performs a 2-oo-3 vote on each data bit from the slices and sets the indicators accordingly.

The output status indicator mode is dependent upon the numerical state of the output channel. Each

output state can be defined to have a particular indicator mode: off, green, red, flashing green, or

flashing red.

The configurable indicator modes allow users to customise the output status indications to suit

individual application requirements. Without customisation, the default indicator modes are suitable for

line-monitored analogue output devices as described below:

INDICATOR STATE DESCRIPTION

Off Output is Off.

Green Output is On.

Green – flashing No Load, output open circuit.

Red Current demand cannot be met

Red – flashing Channel fault, or no field supply voltage

Table 18 I/O Status LEDs

Note: The LEDs indicating channel status may be configured to suit user requirements by

implementing the procedure for configuring the System.INI file detailed in PD-8082B.
