Radio interface to the devices

The circuit protection devices with communication and metering function provide the
7KN Powercenter 1000 with their data via radio. Data can be read from the devices and
changed parameters can be sent to the devices.
Communication is possible via radio as soon as the devices are connected and supplied with
power (minimum 5 A for the 3NA COM fuse).
A 7KN Powercenter 1000 can communicate with up to 24 terminal devices. Each of these
circuit protection devices must join the secure radio network of the Powercenter or, in other
words, each terminal device must be paired with the 7KN Powercenter 1000. The terminal
devices do not communicate among one another, rather communication with the data
transceiver is bidirectional/in a star configuration (no mesh-network).
In order to pair the devices, the RF code of the terminal devices must be scanned, this shares
the device type, MAC address and installation code of the device. Alternatively, this
information can be entered manually. A description of the procedure can be found in the
Installation Manual (https://support.industry.siemens.com/cs/ww/en/view/109791805).
Note
Once the terminal device has been paired with the data transceiver, the installation code is
encrypted and replaced so that each communication connection is separately encrypted.
Therefore it is necessary to reset the communication information in order to be able to carry
out another pairing.
Radio transmission can be significantly influenced by other transmitting devices. It can result
in losses of individual data packages. A recommendation on installation is stated in the
Chapter Installation conditions (Page 24).
