6 Basic functions of the entire system
6.1 Internal cycle times
The cycle time of the system depends on the number of data to be transmitted between the bus controller
CPC10 as well as the number of slots intended on the power distribution system for the electronic circuit
protectors ESX50D-S. The cycle time decreases when using a power distribution board with four slots as
opposed to the cycle time with a power distribution system with 24 slots from 730 ms to 230 ms. During the
aforementioned period the status, the output voltage and the load current of each circuit protector is cyclically
transmitted to the CPC10. This has to be seen independently of the number of connected power distribution
boards SVS201-PWR with which the CPC10 communicates in parallel. The cycle time of the entire system
goes by the longest cycle time of the designed power distribution board. If for instance a power distribution
board with 16 and three more with 8 slots are connected to a CPC10PB-T4, the cycle time will comply with
the 16-slot-board and will thus be 530 ms for all four connected power distribution systems.
It is possible to choose the data quantity for the communication to the superordinate control unit. This can
be achieved by using the different data models. It is therefore possible to transmit either the status, the measuring
values for the load current and the output voltage of the electronic circuit protector or to only send the circuit
protector status to the superordinate control unit. The choice between the various data models is made available to
the user in the GSD file of the control system. These are configuration data which are transmitted to the store
programme control by means of the hardware configuration of the CPC10.

6.2 Hot swap of circuit protectors
The electronic circuit protectors ESX50D-S can be plugged into the power distribution board SVS201-PWR-xx at
any time. The ON/OFF button of the electronic circuit protector has to be in the OFF position.
For safety reasons the electronic circuit protectors ESX50D-S must only be plugged in in the OFF
condition.
