Introduction
OVERVIEW The chapter describes how to configure the D485 Modbus to DeviceNet Converter to allow
GE Multilin relays and meters to communicate on a DeviceNet network. The GE Multilin
MM2 Motor Manager 2 and PQMII Power Quality Meter are used as examples.
GE Multilin relays and meters support a very useful feature called the Modbus User
Map in their software. This feature can be used in configuring the D485 to reduce the
number of Modbus transactions and improve communication speed.
It is assumed that the reader is familiar with serial communication, DeviceNet networks,
and PLC architecture.
