Additional Information for Redundant Processor Modules
A controller with redundant processor modules should be treated as a single system. Make the
following additional steps. The one processor module which is primary/backup is denoted
primary/backup all through.
1. Stop the backup module
a. Set the start mode selector on the backup module in position 2 (STOP).
b. Depress the ENTER button on the backup module.
2. Follow the general instructions above for a single system.
3. By way of conclusion start the backup module.
a. Set the start mode selector on the backup module in the same position as the primary
b. Depress the ENTER button on the backup module.
5.5.17 Loading of Application Program
Several methods of how to dump an application program and how to load the actual backup into
a controller are available. The possibilities and general descriptions can be found in a separate
reference manual AMPL Configuration Advant Controller 400 Series.
Knowledge in handling an engineering tool is necessary to apply general descriptions.
The maintenance organization of the plant is responsible for well developed and adapted
routines in this area.
Below one possible scenario is described to get an overview of the loading. You may see the
instruction directed to “the not so experienced maintenance personnel” which has to take care of
a program load in an emergency situation. The controller has stopped (the processor module
indicate HALT) and a simple system restart (see above section) has failed.
Of course the instructions are only valid under certain circumstances.
Important assumptions are:
• An DUAP application program dump is available on the engineering station hard disk
• The dump is performed in OPERATION mode. If not you must, after loading, make a
manual deblocking of each individual PC program. This simplified instruction does not
support that alternative.
• After the loading the controller will automatically get into OPERATION mode. Always
reflect the consequences to the process.
DANGER
Reflect the personnel and machine safety, see Section 5.5.6, Safety
Regulations.
• The identity of the dump and the net and node number of the controller must be known.
In the example of procedure below the name ABCD and net 11, node 12 are used. Please
observe that the dump usually consists of different segments designated for example:
ABCD0001.AD, ABCD0002.AD and so on.
