In general, the following subsystems and functions are available with redundancy:
•
Mains distribution network
•
Voltage supply, 24 V
•
Voltage regulation, 5 V
•
Battery and charger
•
CPU and memory
•
Network communication
•
GCOM
•
MVI (Multi Vendor Interface) communication
•
RCOM
•
MasterFieldbus
•
Advant Fieldbus 100
•
S100 I/O Bus extension
•
I/O module.
You can add redundancy within a specific controller in a flexible way to meet the desired
demands upon system availability.
The controller utilizes different principles of redundancy for included subsystems. Both hot
stand-by and independent parallel operation are used. Duplicated hardware is primarily used in
what is known as 1:1 implementation.
Maintainability is always provided by diagnostics, fault announcement and adequate unit
exchangeability.

Redundant a.c. networks, or a combination of an a.c. network and a d.c. network, are primarily
connected to separate circuit breakers and power supply units. Secondarily, at 24 V level,
the two networks are wired by diodes. The controller always needs an a.c. supply for use by
certain external equipment such as modems. In the case of redundant a.c. networks, automatic
relay devices are used to maintain the power supply in case of a single network error.
The duplicated equipment is normally in parallel operation, sharing the load. In the event of a
single failure, the full responsibility is taken over bumplessly by one piece of equipment.

Duplicated power supply units for 24 V d.c., secondarily wired by diodes, are utilized.
This is the same redundancy solution as for mains distribution network. The wiring diodes are
distributed to the 5 V voltage regulators in the controller subrack. When redundant powering of
I/O subracks is desirable, a voting unit is used.
