powerline modem for data transmission via the busbar

Brief summary:

The powerline modem is used for data exchange between communication-capable low-voltage switchgear and controlgear across all 3 phases of the low-voltage busbar system. It uses the Access Powerline Communication standard (Access PLC) for data transmission. In this case, one modem ("client" operating mode) is installed in the powerline-capable busbar tap-off unit and another in the power distribution system ("PAN coordinator" operating mode). The devices are connected via RJ45 (Ethernet) .

An external supply voltage is not required. The connection is parameterized via the integrated web server of the modem.

Functions:

• "PAN coordinator" operating mode: Demodulation of the modulated powerline information and conversion to Modbus TCP
• "Client" operating mode: Modulation of the information connected to the RJ45 (Modbus TCP) interface onto the power line
• Automatic configuration, no local configuration required
• Pushbutton: Reset / factory settings
• LEDs: Status display, PLC connected / data transmission, fault indication

• Frequency range: 2 to 50 MHz
• Automatic setup of PLC network
• Automatic Repeat Request (ARQ) improves error detection and reliability of data
