3.1 Design of the entire system
The CPC20 bus controller is the centre
piece of the
ControlPlex
®
system. It allows
consistent communication between the
ESX60D electronic circuit protectors and
the superordinate control level, connected
HMIs and even into the Cloud.
The PROFINET interface to the
superordinate control unit is implemented
as two RJ45 connectors. It allows
connection of the required control unit with
the
ControlPlex
®
system, This enables
display, analysis as well as diagnosis of the
individual measuring values. In addition, it
allows control of the individual electronic
circuit protectors. An additional Ethernet
interface enables direct access of the
integral web server of the bus controller.
Service staff can thus directly access the
system on site. Moreover, access via the
connected infrastructure of the company
is enables and thus global access. OPC
UA* and MQTT* allow transmission of all
measuring values and status information
e.g. to a superordinate cloud application,
independently of the control system.
Revised measuring values of all electronic
circuit protectors are also forwarded to
the automation system. This enables the
user to have unrestricted access to the
safety-relevant functions even in the event
of an interruption. Any occurring failures
will be detected quickly and can be
remedied without delay. The
ControlPlex
®
system effectively reduces system
downtimes and significantly increases
the productivity.
16 power distribution modules with up to
16 2-channel ESX60D electronic circuit
protectors can be directly connected to
the CPC20 bus controller. This number
can be doubled with the transfer module.
Thus the bus controller operates up to 64
channels. This is done in a cycle time of
520 ms.
