Shutdown Indicator
Upon loss of communications with the controller, output
modules enter either a shutdown or hold fault mode. If the I/O
assembly is set to shutdown, the red SHUTDOWN
indicator
will turn on when communications with the controller are lost.
If the I/O assembly is set to hold, the SHUTDOWN indicator
will always be off (see page 11, Fault Mode Jumper).
When the module is installed in the I/O chassis or when logic
power (from the I/O power supply modules) is first applied to
the module, it will be in the shutdown mode until the first
output scan, regardless of the fault mode jumper settings.
Also, removing two I/O transceiver modules, two I/O power
supply modules, or two power legs will cause the module to be
in the shutdown mode.
Output Status Indicators
The output status indicators are yellow LEDs located on the
logic-side (coil) of the relay output. There are eight output
status indicators — one for each output. These indicators are
lit when the output relay coil is energized, closing the
normally open contact.
