2 Installing and Configuring the Module
In This Chapter
Module Configuration ............................................................................20
Module Data Files .................................................................................21
This chapter describes how to install and configure the module to work with your
application. The configuration process consists of the following steps.
1 Use RSLogix 5 to identify the module to the processor and add the module to
a project.
Note: The RSLogix 5 software must be in "offline" mode to add the module to a project.
2 Modify the example ladder logic to meet the needs of your application, and
copy the ladder logic to the processor. Example ladder logic files are provided
on the CD-ROM.
Note: If you are installing this module in an existing application, you can copy the necessary
elements from the example ladder logic into your application.
The rest of this chapter describes these steps in more detail.
The first step in installing and configuring the module is to define whether the
block transfer or side-connect interface will be utilized. If the block transfer
interface is to be used, remove the Compact Flash Disk from the module if it is
present and insert the module into the rack with the power turned off.
If the side-connect interface is utilized, make sure the file SC_DATA.TXT on the
Compact Flash Disk contains the correct configuration file number. You can run
the setdnpsc.exe program to set the configuration file number to be used with
your application. Install the module in the rack and turn on the power. Connect
the terminal server to the module's debug/configuration port and exit the program
by pressing the Esc key followed by the 'X' key. This will cause the program to
exit and remain at the operating system prompt. Run the setdnpsc.exe program
with a command line argument of the file number to use for the configuration file.
For example, to select N10: as the configuration file, enter the following:
SETDNPSC 10
The program will build the SC_DATA.TXT on the Compact Flash Disk (C: drive in
the root directory).
The next step in module setup is to define the data files to be used with the
application. If the block transfer interface is used, define the data files to hold the
configuration, status and user data. Enter the module's configuration in the user
data files. Enter the ladder logic to handle the blocks transferred between the
module and the PLC. Download the program to the PLC and test the program
with the module.

MVI71-GSC ♦PLC Platform Installing and Configuring the Module
Generic Serial Communication Module
Page 20 of 82 ProSoft Technology, Inc.
January 31, 2008
If the side-connect interface is used, minimum ladder logic is required for data
transfer. The user data files to interface with the module must reside in
contiguous order in the processor. The first file to be used by the interface is the
configuration file. This is file number set in the SC_DATA.TXT file using the
SETDNPSC.EXE program. The following table lists the files used by the side-
connect interface:
File Number Example Size Description
Cfg File N10 300 Configuration/Control/Status File
Cfg File+1 N11 500 Data transferred from the module to the processor
Cfg File+2 N12 500 Data transferred from the processor to the module
Even if the files are not required for an application, they still are reserved and
should only be used for that purpose. The read and write data contained in the
last set of files possess the data transferred between the module and the
processor. The read data file (Cfg File + 1) will contain data received on the
communication port and passed to the module. The write data file (Cfg File + 2)
will contain data passed to the module from the processor to be sent out the
communication ports.
Special care must be taken when defining the files for the side-connect interface.
Because the module directly interacts with the PLC processor and its memory,
any errors in the configuration may cause the processor to fault and it may even
lose its configuration and program. After defining the files and populating them
with the correct data, download the program to the processor, and place the
processor in run mode. If everything is configured correctly, the module should
start its normal operation.
If all the configuration parameters are set correctly and the module is attached to
a network, the module's Application LED (APP LED) should remain off and the
backplane activity LED (BP ACT) should blink very rapidly. Refer to the
Troubleshooting section if you encounter errors. Attach a computer or terminal
to Port 0 on the module and look at the status of the module using the
Configuration/Debug Menu in the module. Refer to the Configuration/Debug
Port section for a complete discussion of the use of this feature.
1.8 Module Configuration
In order for the MVI71-GSC module to function, a minimum amount of
configuration data must be transferred to the module. The following table
provides an overview of the different types of configuration data that the module
