Multi-unit system
Load connection on devices in multi-unit operation
A multi-unit system with max. 7 devices is recommended. Theoretically
up to 64 devices can be connected to the bus. From approx. 8 devices
the communication is reduced. As a result, the dynamic performance
of individual devices cannot be achieved with more than 8 devices.
Here it is recommended to use the Multi-Rack Controller (MRC), for
information on the realisation of larger multi-unit systems see dedicated
instructions.
Device addressing
The device address comprises an upper address range (AH) and a
lower address range (AL).
During the configuration of the related address range, the device type
and the master-slave principle play a role, along with the type of configuration.
Master-slave principle
The set values are provided to the master device, e.g. via HMI or the
PC using the TopControl application.
The master device passes on the parameters to its slaves via the internal
system communication. The individual slave devices in the multi-unit
system convert the set values specified into the related output values.
4.4.2. Load connection on devices in multi-unit operation
Multi-unit system supplied from the factory
The load connection is configured on multi-unit systems supplied from
the factory. The minus and plus connections on the individual TC.GSS
power supplies are combined to form a system load terminal. The load
is connected to this load terminal.
Special aspects of the multi-unit system in relation to the interlock circuit
and the sense function are taken into account.
