Multi-Master Principle
It is important to know that the load share and load-dependent start/stop functionality is subject to a multi-master
principle. This means that there is no dedicated master and slave function. Each DSLC-2 decides for itself how it
has to behave. The benefit is that there is no master control, which may cause a complete loss of this functionality
in case it fails. Each control is also responsible for controlling common breakers like a mains circuit or generator
group breaker.
Load Share Monitoring
The DSLC-2 provides the following monitoring function for load sharing:
Multi-Unit Missing Members
The multi-unit missing members monitoring function checks whether all participating units are available (sending
data on the Ethernet line).
Switches
Please use a 10/100 Mit/s Ethernet switch if more then two devices should be connected.
General Load Share Information
The maximum number of participating DSLC-2 devices for load sharing is 32. The maximum number of
MSLC-2 devices is 16.
The following parameters affect the bus load:
• Baud rate
• Transfer rate of load share messages
• Visualization
