5.6 Operating mode: Firmware Update Mode
The devices are supplied with a software programmed according
to their functionality. If the functions of the devices are extended, this will be carried out in the firmware. It is therefore necessary to
carry out a firmware update if the new functionality shall be used.
6 Basic functionalities of the entire system
6.1 Internal cycle times 6.2 Hot swap of circuit protectors
The cycle time of the system depends on the number of data
to be transmitted between the CPC20 bus controller and the
projected slots for the ESX60D electronic circuit protectors.
It is possible to choose the data quantity for the communication
ot 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 GSDML 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 CPC20.
The cycle time per bus with 16 18plus-AM03 modules is approx.
520 ms for the cyclical data. A window of 70 ms is kept free for
non-cyclical data. In total, this is a max. cycle time of 590 ms.
The ESX60D electronic circuit protectors can be plugged
into the 18plus-AM03 power distribution module at any time.
After plugging in a circuit protector, it will automatically be
parameterised if parameters are available for the slot in question.
Transmission of the parameters will be without interruption of the
cyclical data exchange between the CPC20 and the ESX60D
electronic circuit protector.
