Page 5: Introduction
Introduction ® The Niobrara QUCM is a TSX Quantum compatible module that is capable of run- ning multiple applications for performing communication translations between serial protocols. This document covers an application that allows a Modbus RTU master to communicate with 3964(R) devices. This setup allows a Modbus master to be placed in a point to point configuration with a single 3964(R) device. - Page 6 6 Introduction QUCM 3964(R) Application Manual...

If connecting to a Modicon PLC, Port 1 of the QUCM-L will be set to be RS-232. The Niobrara cable MM2 is ideal for this connection since it includes an RJ45 RS-232 connection for the QUCM-L and a 9-pin male RS-232 Modicon-style pinout for the PLC. -

Page 9: Port 2 To The Personal Computer
This link may be a serial connection from a COM port on the personal computer to the RS-232 port on the QUCM-S. The Niobrara MM1 cable may be used for this connection. This cable is shown in Figure 2-3. - Page 10 Will load the file into application 1’s flash and set the program to automatically start on power-up. Place Switch 1 in RUN. The RN1 light should come on. Place Switch 2 in HALT. Connect the Modbus master to QUCM port 1 with an MM2 cable. 10 Installation QUCM 3964(R) Application Manual...

The message timeout feature allows the user to select how long the QUCM will wait for a reply to a query. The default timeout is 400ms. The timeout is fully programma- ble by typing the desired time in milliseconds. Valid times are 0 to 30000ms. 14 Modbus to 3964(R) Bridge QUCM 3964(R) Application Manual... -

QUCM will receive the response at port 2, convert the message to Modbus RTU, and route back out port 1. The Bridge/MUX will re- ceive the reply, and route the appropriate Modbus Plus message back to the PLC. QUCM 3964(R) Application Manual Examples 15... -
