Your first task is to add the MVI56E-MCMR module to the project.
1 Use the mouse to select DEFAULT MODULE in the tree view, and then click the right mouse button to open a shortcut menu.
2 On the shortcut menu, select CHOOSE MODULE TYPE. This action opens the Choose Module Type dialog box.

3 In the Product Line Filter area of the dialog box, select MVI56E. In the Select Module

Type dropdown list, select MVI56E-MCMR, and then click OK to save your settings and return to the ProSoft Configuration Builder window.


This section describes how to configure the module as a MODBUS MASTER device. The Master is the only device on a Modbus network that can initiate communications. A Master device issues a request message, and then waits for the slave to respond. When the slave responds, or when a timeout has occurred, the Modbus Master will then execute the next command in the list.

The following ProSoft Configuration Builder sections contain the Modbus Master configuration. You must configure all three sections.
1 The BACKPLANE CONFIGURATION section sets up the backplane communication between the MVI56E-MCMR module and the ControlLogix processor (page 46).
These settings include register addresses for ReadData and WriteData. You can configure up to 5000 data registers in the module to exchange data with the ControlLogix processor.
2 The MODBUS PORT1 and MODBUS PORT 2 sections configure the Modbus application serial ports (page 47). These sections configure parameters such as baud rate, parity, data bits, stop bits, and command response timeout.
3 The MODBUS PORT 1 COMMANDS and MODBUS PORT 2 COMMANDS sections define a polling table (command list) for the Modbus Master (page 50). These sections contain the addresses for devices on the network, the types of data (Modbus Function Codes) to read from and write to those devices, and the location to store the data within the module’s 5000 data registers.


Note 1: On your computer, you must have “Network Administrator” privileges to install this software.
Note 2: Please open and read the release notes on the CD before starting the installation. The release comments are located in the root directory of CDROM.

Install comDTM:
1. Insert the comDTM CD into the CD-ROM drive of your computer.
2. Many computers will automatically start installing programs within a few seconds. If the installation did not start on your computer, click the Start button, select Run, and then type Explorer. Click OK to start Windows Explorer. In Windows Explorer, open the My Computer icon and search for the CD-ROM drive. Double click on the file ‘Setup. exe’. This operation will launch the installation wizard.
3. Follow the instructions in the installation wizard to install the program.
4. Click Finish to complete the installation process. If the computer prompts you to restart the computer, save the program you are running, close other applications, and then restart the computer.

Note: During the installation process, the computer will prompt you whether to accept or change the location of the database folder. The default location is in the Program Files path of your local hard drive (usually drive C:). If you plan to have multiple workstations access the same database folder, you should choose a network drive so that other workstations can access the database.
