If the side-connect interface is utilized, make sure the file SC_DATA.TXT on the
Compact Flash Disk contains the correct first file number. You can run the
setdnpsc.exe program to set the 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 first file. For example, to select
N10: as the first 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
user data (read and write data). 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.

If the side-connect interface is used, no 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 status/control 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:
