4.1.1 Working Modes
Advant Controller 410/450 has four working modes:
OPERATION, CONFIGURATION, STOPPED and OFFLINE.
The LED display on the processor module front indicates the working mode with the codes
P1, P2, -3 and -4, respectively.
P1, working mode OPERATION:
The processor module executes the application program. This is the normal status of an
Advant Controller. The system can then perform control tasks and control the process
outputs.
P2, working mode CONFIGURATION:
The processor module does not execute the application program.
You can configure the controller system and the application program.
-3, working mode STOPPED:
The processor module does not execute at all.
The main CPU performs self-tests to check some basic controller functions.
The process outputs have defined states (zero).
-4, working mode OFFLINE:
The processor module executes low-level fault-tracing commands only.
Usually performed by ABB personnel.
The process outputs have defined states (zero).
During the boot phase and during the time of transition between certain working modes the
display will indicate intermediate states with the help of a sequence of special codes.
These codes are relevant at fault finding and system analyses by ABB personnel only.
Additional Information for Redundant Processor Modules
Redundant processor modules are two individual processor modules PM511. When the system
is operating, one of these is always chosen to function as PRIMARY, while the other unit,
assuming that it is installed and error-free, serves as the BACKUP.
The primary unit provides the same working modes and performs the same functions as an
Advant Controller 450 with a single processor module (that is without redundancy).
During operation, the LED displays on the front of the processor modules are used to provide
information regarding the modes in which the processor modules are executing.
The primary unit’s display reflects the system’s working mode P1, P2, -3 or -4 (see above).
