Installing Your ControlNet PLC5 Processor

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.
➀
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
➁
If an EEPROM module is not installed and processor memory is valid, the processor's
PROC indicator blinks and the processor sets S:11/9, bit 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.
➂
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.
➃
A processor fault (solid red PROC LED) occurs if processor memory is not valid.
➄
You cannot clear processor memory when this switch is on.
