System halt codes are shown on the processor module character display.
You can find solid information along with the halt code/system message and fault finding
descriptions in Section 5.4, Error Messages and Section 5.5, Fault Finding and User Repair
below.
5.4 Error Messages
There are two kinds of error messages in an Advant Controller system:
• Halt codes
– On the character display on the processor module front
– More detailed information read from the memory by an engineering station.
• System messages
– Accessible from an engineering station
– Accessible from an operator station like Advant Station 500 Series.
5.4.1 Halt Codes
A system halt code is shown on the processor module character display but more information,
which can be read from the memory, can often be required. This method is based on the storage
of halt code and attached information, in special memory areas, by the built in diagnostics
before the system is stopped. The information can then be read by starting the system in
working mode OFFLINE.
Typical halt codes and corrective measures are listed in Appendix H, Halt Codes.
If this method does not function, the fault is probably caused by a serious CPU malfunction.
The fault must then be determined without the use of an engineering station.
5.4.1.1 Reading of Halt Codes
Detailed information attached a halt code can be read using the engineering station command
LSYSHI. Proceed as described in Section 5.4.2.1, Reading of System Messages.
5.4.2 System Messages
System messages are generated as soon as a malfunction is detected or there has been some
other important change of status in the controller. The messages are stored in a queue in the
controller memory.
Typical system messages and corrective measures are listed in Appendix I, System Messages.
Only system messages which are of particular interest to the final user are included. That is
messages which point out possible malfunctions which can be easily corrected by the user
himself. System messages not described here are to be noted and forwarded to ABB Automation
Products AB to determine if any action is necessary.
