Providing basic web-enabled displays, the ECC21 furthers the migration of PowerLogic systems to open networks and provides direct, high speed Ethernet connectivity. In addition, with embedded HTML pages, it allows for easy device setup and real-time power system information from the circuit monitors through a standard web browser. Similar information can also be viewed for devices daisy-chained to the ECC21 onboard RS-485 port. 

• MODBUS/TCP protocol support - Based on plug and play technology, the ECC21, with MODBUS/TCP protocol support, plugs into an expansion slot on the circuit monitor providing direct connection to the Ethernet network using either UTP or fiber cabling. 
• RS-485 MODBUS master port - An RS-485 MODBUS master port on the ECC21 supports a daisy-chain of up to 31 additional devices without a repeater, allowing the CM4000 with ECC to act as an ethernet gateway for the devices.
