Power Line Communication (PLC) Expertise


Power-line Communication (PLC) provides a mechanism for reusing existing electrical wiring for data communications. As these wirings are already present everywhere to power various electrical appliances, there is a huge saving on additional infrastructure.

We at Aftek realize the tremendous potential offered by PLC in home automation and security systems and have developed advanced solutions for home and building automation as well as in AMR / AMM sector.

Aftek's PLC expertise can be readily observed with our proprietary DigiHome products. We offer state of the art and highly customizable solutions for intelligent homes using PCL SoCs. Additionally, we have in-place framework for energy-saving infrastructure for intelligent street lighting, society lighting and more.

Aftek Smart Metering Solution with ADD1010 PLC SoC

Aftek has collaborated with ADD Semiconductor for the development of Smart Metering Solution. ADD Semiconductor is a world leader in the development of SoCs for communication over Powerline, Automatic Meter Management and DSP applications. Moreover, they are one of the founding members of PRIME and are involved in an ambitious international development plan for a Powerline standard.

The ADD1010 is a Power Line Communications System on Chip, which implements a full PLC node. This chip is designed to be used by meter manufactures. It provides a low cost and small size solution for AMR and AMM system using narrow band power line communications.

      • PHY
      • MAC
      • ADD8051C3A MCU

The ADD1010 implements a full PLC node using FSK or S-FSK modulations compatible with IEC61334-5-1, IE C61334-5-2. It also includes a hardwired Medium Access Controller (ADD1210). It has been developed to reduce the CPU computational load in a PLC system, allowing the microcontroller to be used in other application tasks.

MAC functional capabilities of ADD1010 involve the construction of message packets, adding FEC (Forward Error Correcting Code) values to bytes and FCS (Frame Check Sequence) to packets. Additionally, ADD1010 MAC is compatible with EHS, KONNEX and IEC61334-4-32. However, the SoC design is versatile enough to allow users to create a wide range of datagram structures with the only constrain of FEC and FCS hardware codes. The MAC can be set in a bypass mode allowing direct connection between the microcontroller and the modem to support old FSK software that doesn't include the MAC.

The PLC modem of ADD1010 (ADD1310) can use a single power supply of 3.3V and a few external components. It supports several AFE configurations suitable for Home Automation or AMR. It can replace the traditional analog PLC modem and can use the same software libraries or a simplified version, if the hardwired MAC is used.

The MCU under the ADD1010 and ADD8051C3A supports a range of peripherals that can be used to connect the energy metering chips, segmented LCDs, UARTs, Boot Flash and more. These features make the ADD1010 an ideal proposition for Aftek's energy metering solution.
