Minneapolis, MN, Sept. 19, 2005 — Cannon Technologies Inc. has made available a versatile automated meter reading (AMR) device designed for remote reading of popular digital polyphase meters in 4 to 6 seconds over utility-owned power lines. The multi-voltage/multi-protocol MCT-470 is the first “micro-RTU” capable of bi-directional serial communication with digital meters from different manufacturers over power distribution lines.
The MCT-470 supports Elster ALPHA Plus meters, Landis+Gyr S4 and S4e meters, and Itron SENTINEL meters, from a single cost-effective device at any of the standard meter voltages (120, 240, 277, and 480 volts). Cannon Power Line Communication (PLC) features on-demand readings from these meters in 4 to 6 seconds, enabling the return of most data registers and the sending of certain configuration commands such as “demand reset,” TOU register switch, and time synchronization.
The MCT-470 firmware can be upgraded in the field using the Cannon Technologies’ Handheld Tester loaded with MCT-Minder software, which allows upgrading to additional protocols such as DNP 3.0, planned for the future.
The MCT-470 also features pulse and status inputs, plus trip/close control relays, putting the device into the micro-RTU class at a much lower cost due to the embedded power line communications. With this combination of inputs and relays, the MCT-470 can be used to control irrigation pumps, gen sets and downline reclosers in addition to bringing back metering information.
Cannon PLC also communicates with single-phase digital meters from popular manufacturers, demand response equipment, and capacitor bank controls, all over the same low-cost power line network.
