Section 6 Communications
6.1 Introduction
The MPACt 1500 controller has three types of
communications connections: an RS-485 serial port, an
ethernet port, and a USB port.
Use Ethernet or serial connections to connect the
transfer switch to a personal computer for system
monitoring and control using Kohlerr Monitor III
software or other Modbus applications.
The controller uses Modbusr TCP/IP communication
protocol over the Ethernet port. The controller uses
Modbusr RTU communication protocol over the serial
ports. The Modbus registers are available in the
Modbus Protocol manual. See the List of Related
Materials.
Note: Modbusr applications other than Monitor III
software require a Modbus software driver
written by a trained and qualified systems
programmer.
The USB port is used for file transfer between the
controller and a memory device. The USB port is a
standard 4-pin USB connector. The USB Access screen
appears when a device is connected to the USB port.
See Section 6.4 for instructions to transfer files through
the USB port.
