7.9 Redundancy
The bus redundancy technology of the repeater modules is very advanced. A redundant system can be built
using 10 parallel cables. This architecture provides extremely high availability. It is compatible with the RLM01
from ABB.
The redundancy procedure is very simple;
All the repeater channels of the specific application have to be assigned to the same network group. The
repeater channels that carry the redundant task have to be activated with the RED switch. After a reset or
power-up the redundancy system works directly.
ComBricks locks itself to the first redundant channel that has a valid start delimiter.
If this channel does not have valid telegrams anymore, ComBricks locks itself to the next redundant channel
with a valid start delimiter. There is no logic which redundant channel is selected.
It is recommended to use single-channel repeater modules for redundant applications. If a module
should fail, the replacement (pull/plug and wiring) will not affect the other redundant repeater
modules (channels).
Fig. 55 illustrates an application with 3 redundant segments. 3 Repeater modules of each ComBricks are set
with the RED switch set to ON and are wired to the redundant segments.
The devices and the controller(s) are connected to the regular repeater modules. The maximum amount of
devices which is allowed behind a regular repeater module depends on the application (between 1 and 31
devices).
