Configure the I/O Chassis
Regardless of this switch setting, outputs are turned off when any of the following occurs:
processor detects a runtime error
an I/O chassis backplane fault occurs
you select program or test mode
you set a status file bit to reset a local rack
If
an EEPROM module is not installed
and processor memory is valid, the processor
s PROC LED indicator blinks,
and
the processor sets S:1
1/9, bit 9
in the major fault status word. T
o clear this fault, change the processor from
program mode to run mode and back to program mode.
If the processor’s keyswitch is set in REMote, the processor enters remote RUN after it powers up and has its
memory updated by the EEPROM module.
A processor fault (solid red PROC LED) occurs if processor memory is not valid.
You cannot clear processor memory when this switch is on.
