 Key Features
 
  • Front Panel RS232 port for programming and troubleshooting
  • Optional embedded Ethernet port
  • Optional Profibus DP/DPV1 or DeviceNet via dedicated port
  • Multiple Protocols - Modbus RTU, Modbus TCP/IP
A front RS232 port is provided for downloading setpoints and interrogating the relay using the EnerVista™ 369.
Three independent rear RS485 ports offer the customer flexibility and performance for their communication network. The 369 can
communicate at baud rates up to 19,200 bps using the industry standard Modbus® RTU protocol. Fiber optic (option F) Profibus interface 
(option P), DeviceNet (option D), and Ethernet (option E) ports are also available. The optional direct connect RJ45 Ethernet port 
can be used to connect the 369 to 10 Mbps Ethernet networks. The communication system of the 369 is designed to allow simultaneous 
communication via all ports.

Using Ethernet as the physical media to integrate the 369 to Local or Wide Area Networks replaces a multipoint wired
network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing operating costs.
