3.4.3 USB service interface, terminals X61
The USB interface serves for connection of the service computer. By means of the available user software
ControlPlex®
Views it is possible to import the measuring values of the individual circuit protectors, to change
parameters and to switch the devices on or off. The connection is realised by means of USB-2.0 type B. The
length must be less than 3 m. In the event of a bus communication with the superordinate control unit, the
user software has only reader access. If a change of the device parameters should be made possible on behalf of
the user software, this has to be explicitly released by the superordinate control unit.
3.4.4 Bus interfaces to PROFIBUS-DP, connector socket X81
The PROFIBUS-DP connection is realised via a 9-pin SUB-D connector. It allows direct connection of the
device with other PROFIBUS-DP participants. For mounting and special selection of cables and connectors
please see mounting guideline of the PNO.
3.4.5 LED PWR
The PWR diode lights up green if voltage is applied.
3.4.6 LED CE
The LED CE shows the status of the communication unit. For more detailed information please see chapter
»Signalling of various operating modes«.
3.4.7 LED CM
The LED CM shows the status of the communication between the communication unit and electronic circuit
protector. For more detailed information please see chapter »Signalling of various operating modes«.
3.4.8 LED MS
The LED MS shows the status of the internal PROFIBUS-DP communication module.
3.4.9 LED NS
The LED NS shows the network status of the communication of the internal PROFIBUS-DP communication
module to the PROFIBUS-DP master.
