Fault Codes
Fault routines execute when a PLC-5 processor encounters a run-time
error (major fault) during program execution. 3.
A fault routine processes the major fault bit found in S:11 and
determines the course of program execution based on the fault bit
present. Fault routines provide a means to either:
• systematically shut down a process or control operation
• log and clear the fault and continue normal operation
For more information about fault routines, see Enhanced and Ethernet
PLC-5 Programmable Controllers User Manual, publication
1785-6.5.12.
Clearing Faults When a major fault occurs, you need to clear faults before your
process can continue.
Additional Major Fault Codes The processor stores fault codes in word 12 of the processor status
file (S:12). The following table lists new major fault codes specific to
the ControlNet processor.
!
ATTENTION: Clearing a major fault does not correct
the cause of the fault. Be sure to examine the fault bit
and correct the cause of the fault before clearing it.
For example, if a major fault is encountered that causes
bit S:11/2 to be set, which indicates a programming
error, do not use a routine to clear the fault until you
correct your program.
This fault code: Indicates this fault: Take this corrective action:
200 ControlNet scheduled output data missed.
The processor is unable to transmit the scheduled data it is configured to
transmit.
Check your network for missing terminators or
other sources of electrical noise (see the Industrial
Automation Wiring and Grounding Guidelines,
publication 1770-4.1)
201 ControlNet input data missed.
The processor is unable to process incoming data from the network
Check your network for missing terminators or
other sources of electrical noise (see the Industrial
Automation Wiring and Grounding Guidelines,
publication 1770-4.1).
202 This error code is reserved. Contact your local Rockwell Automation
representative if you get this message.
203 This error code is reserved. Contact your local Rockwell Automation
representative if you get this message.
204 Too many output connections per NUI. Make scheduled outputs with short Requested
Packet Intervals longer and reaccept edits for the
ControlNet configuration.
