9.3.3. BUS FAULT Indicator ON

The BUS FAULT indicator on the CPU would be ON to indicate an error on CPU, or to indicate an error on I/O module
together with the ERROR indicator on an I/O module. If an error occurs in an I/O module, the status of the BUS FAULT
indicator on the CPU will be the same as that of the ERROR indicator on the I/O module. If multiple errors occur in the I/O
modules, the BUS FAULT indicator on the CPU will keep ON (not blinking). For example, if the ERROR indicator on
module A is ON and the ERROR indicator on module B blinks, the BUS FAULT indicator will keep ON. When the error in
I/O module A is cleared, module B will blink and the BUS FAULT indicator will blink as well. Refer to the section
more information about the indicator behaviors of each module.
