Best in class, the 469 Motor Protection System has been further enhanced with new features
including embedded DeviceNet Protocol and built-in Ethernet Communications.

Embedded DeviceNet and Ethernet Communications

DeviceNet Protocol allows the 469 to communicate to remote control centers via DeviceNet based networks, found in many industrial facilities. Embedded Ethernet communication allows the 469 to be connected directly to Ethernet Local/Wide Area Networks (LAN/WAN) supporting baud rates of up to 10Mbps, using Modbus TCP/IP protocol, via an RJ45 port located on the back panel of the relay.

Advantages of Direct Connection between the IED’s and the Network:

Reduce installation costs & improve reliability - Eliminates the need for expensive transceivers, protocol converters, intermediate communications processors or data concentrators, making your communications network simpler, more reliable and cost effective. Improves Access to Instrumentation Devices - For device-level diagnostics not easily accessible or available through hardwired I/O interfaces.

Advantages of Embedded Communications:

Economical access to information – Direct connection to DeviceNet Networks or 10 Mbps Local/Wide Area Networks (LAN/WAN) to access relay information such as settings, oscillography, trending data, and sequence of event recorders. More Reliable Communications – Eliminates external devices, their associated costs and reduces number of possible points of failure. Reduce installation & maintenance cost – Less components to install, commission and maintain
