POWERLOGIC SERIES 4000 CIRCUIT MONITOR NOW AVAILABLE WITH ETHERNET COMMUNICATIONS CARD
August 22, 2000


A new Ethernet Communications Card (ECC) allows customers to connect their POWERLOGICŪ CM4000 Circuit Monitor to their LAN/WAN system for direct Ethernet communications. The ECC provides high-speed communications via 10/100baseT or 100baseFX connections.

“By connecting their power monitoring and control systems directly into their Ethernet system, customers can enhance system communications and maximize the return on their infrastructure investment,” said Gary Jones, Director of the Power Monitoring Organization within Square D. “Adding the ECC to the POWERLOGIC System is one more step in our efforts to meet the demand of customers for open network devices.”

Based on plug and play technology, the ECC plugs into an expansion slot on the circuit monitor much like a video card plugs into the expansion slot in a PC. The connection to the Ethernet network can be made using either UTP or fiber cabling. An RS-485 Modbus master port on the ECC supports a daisy-chain of up to 31 additional devices, allowing the CM4000 with ECC to act as an Ethernet gateway for the devices.

The ECC supports Modbus/TCP protocol. Embedded HTML pages allow for easy device setup and supply real-time power system information from the CM4000 circuit monitor through a standard web browser. Similar information can also be viewed for devices daisy-chained to the ECC’s onboard RS-485 port.
