Section 5.5.2 Diagnostics and Fault Announcement
3BSE 002 415R701 Rev A
5-7
Disturbances and system halt caused by software error are commonly solved by a manual
system restart. Sometimes you must load the application program, reinforcing the need for
actual backup copies. In such situations, it is strongly recommended that you take careful note
of all available stored error codes and system messages before an eventual program loading and
new initialization. Then contact ABB for further information.
External faults in process wiring and transducers can also affect the function of the controller.
However, this type of fault is not discussed in this manual.
Debugging of PC programs is described in the reference manual AMPL Configuration Advant
Controller 400 Series.
5.5.2 Diagnostics and Fault Announcement
Both hardware and software in an Advant Controller 450 are provided with supervision against
system fault. For a survey of the diagnostics, see
.
The following indicating facilities apply on different levels:
The
Controller and I/O Cabinet
•
LED indicators on circuit boards:
–
Green LED, RUN, indicates normal function.
–
Yellow LED indicates an active signal, for example, status of digital input (DI) or
digital output (DO).
–
Red LED, FAULT, indicates malfunction.
•
Character display on processor module front:
–
Show working mode, error or halt code. See
Plant Central Fault Annunciator
The Advant Controller 450 provides two run/alarm relays located in the Status Collector
TC520. One relay for each possible processor module. The relay contact which is normally
closed, opens at system halt (processor module halt). Use the contact function in any desired
application function, for example, creating audible alarm or interlocking of certain process
objects in the event of a controller safety shutdown.
Engineering Station
•
Halt codes stored in a stopped system. Read with the command LSYSHI:
–
Show error or halt code. See
.
•
System messages. Read with the command LSYSM ALL:
–
Most information in coded form
–
Give information about probable cause of malfunction.
