Diagnostic LEDs

The module contains diagnostic LEDs that help you identify the source of
problems that may occur during power-up or during normal operation. Power-up
and channel diagnostics are explained in Chapter N, Testing Your Module.
The module communicates with the SLC 500 processor and receives +5 VDC
and +24 VDC power from the system power supply through the parallel
backplane interface. No external power supply is required. You may install as
many modules in the system as the power supply can support.
At power-up, the module checks its internal circuits, memory, and basic
functions. During this time the module status LED remains off. If the module
finds no faults, it turns on its module status LED.
After completing power-up checks, the module waits for valid channel
configuration data from your SLC ladder logic program (channel status LEDs are
off). After channel configuration data is transferred and channel enable bits are
set for one or more channels, the module turns on its channel status LEDs. Then
it continuously converts the inputs to the data format you selected for the
channel.
