6.2 Power Line Modem (PLM)
An optional Power Line Modem card can be integrated in the AURORA inverter.
This system allows to transmit and receive the data directly from the AC mains
cable, using advanced algorithms to improve communication performance and
increase reliability of data transmission over noisy electrical lines.
To collect the data transmitted over the PLM link:
• Use a PLM/RS232 interface converter such as model number PVI-PLMREC-EU
to connect to a PC,
In either case no additional physical connections between the inverter and the
receiver are needed, as the communication uses the power lines.
In case of installations in buildings wired with three-phase systems please make
sure that the AURORA inverter and the receiving equipment are both on the same
phase.
The nominal transmission range is 300yards (about 300m). However, the range
may be limited in case of high electromagnetic interference of the power lines. In
case of extremely noisy power lines we recommend using a separate set of wires
dedicated to the PLM communication, or to use the RS-485 serial link.
The maximum transmission rate of the PLM is 2400 bps.
