Allen-Bradley ControlNet PLC-5 User Manual

1785-UM022B-EN-P - February 2002
Installing Your ControlNet PLC-5 Processor 1-9
Setting the I/O Chassis
Backplane Switches
Set the I/O chassis backplane switches using a ball-point pen to set
each switch.
Important: Do not use a pencil because the tip can break off and
short the switch.
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 indicator blinks and the processor sets bit S:11/9 in the major fault status word.
To 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 mode
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.
