Appendix B
Processor Module Error
and Status Codes
All AutoMax Processor module error and status codes (displayed on the two
sevenĆsegment LEDs on the faceplate) are listed below, organized first by error
type and second, in numerical/alphabetical order.
Processor Overload
00 CPU overload
Corrective action: move one or more application tasks to other Processor
modules in the rack, or make scan times longer.
PowerĆUp Diagnostics
The following error codes are displayed while the Processor module performs
powerĆup diagnostics.
0.0.
EPROM failed
0.1.Ć 0.3. Bad CPU
0.4. Internal bus error test failure
0.5. Parity test failure
0.6. External bus error test failure
0.7. Processor in the wrong slot
1.0. Ć 1.6. RAM failure
2.0. I/O protection failure
2.1. PIO failed
2.2. PC accelerator failed
2.3. 8253 timer/counter failed
2.4. SIO failure
2.5. Communications interrupt failed
2.6. SIO interrupt failed
2.7. 8253 counter/timer interrupt failed
2.8. Local watchdog failed
3.0. Bad backplane
3.1. Multibus parity test failure
4.0. Ć 4.5. Common memory RAM failure
4.6. Common memory system watchdog failure
5.0. Processors with incompatible EPROMs in the rack.
Corrective action: replace the Processor, or replace the Common Memory
module if error codes 4.0.Ć 4.6. remain on.
Run Time Errors
02 Task or Configuration checksum failure
Corrective action: clear the error in the error log. This will also clear the LEDs.
Reload the parameter files and application tasks to the UDC module in the slot
referenced in the error log.
