Module Status LED
The module status LED is a two-color (red and green) LED. It
shows the operating condition of the DSO module. There are
three possible operating conditions:

enabled by the control module.
Solid Green
DSO module is enabled by and communicating with the con-
trol module.
Solid Red
I/O expander bus fault timer error (time-out condition).
Output Status LEDs
There are eight output status LEDs. Each LED indicates the
status of the digital output corresponding to the number
printed to the right of the LED. There two possible states for
each LED:
Off
The output is not energized and represents a logic zero.
Solid Red

Fuse Status LED
The fuse status LED shows condition of the output fuses (when
enabled) for the active outputs on the DSO module. There are
two possible states for the fuse status LED:
Off
All output fuses are operating properly.
Solid Red
One or more of the output fuses has failed.
START-UP PROCEDURES
The start-up of the DSO module is controlled by the function
block configuration of the control module. Specification S1 of
function code 83 in the control module configuration tells the
control module the address of the DSO module. The DSO
address dipswitch settings must match this address or the
DSO module will not be enabled. Refer to the
Function Code
Application Manual
