Keypad and Display The 469 has a keypad and 40 character display for local monitoring and relay configuration without the need for a computer. Up to 20 user-selected default messages can be displayed when inactive. In the event of a trip, alarm, or start block, the display will automatically default to the pertinent message and the Message LED indicator will flash.

Communications The 469 is equipped with three standard serial communications ports, one RS232 located in the front panel for easy troubleshooting and programming, and two RS485 in the rear of the relay. Optional 10BaseT Ethernet and DeviceNet ports are also available. The rear RS485 ports provide remote communications or connection to a DCS, SCADA, or PLC. The RS232 and RS485 ports support user programmable baud rates from 300 to 19,200 bps. The optional Ethernet port can be used to connect the 469 to 10 Mbps Ethernet networks. The three serial ports support ModBus® RTU protocol, while the Ethernet port supports ModBus® RTU via TCP/IP protocol. The communication system of the 469 is designed to allow simultaneous communication via all ports. Using Ethernet as the physical media to integrate the 469 to Local or Wide Area Networks, replaces a multidrop-wired network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing monthly operating costs.
