The PLC-5 and SLC-500 command set require the use of files. These files are
emulated in the module. The module defines these files each as containing 200-
word registers that overlay the internal database. The following table shows the
relationship of the files to the user data area of the internal database:
File
Database Register
N7:0
0
N8:0
200
N9:0
400
N10:0

Note: The way these files are emulated depends of the First File and File Size parameters. The
previous example shows using the First File parameter set to 7 and the File Size parameter set to
200.
In order to retrieve data from the modules database register 200, the remote
master would issue a command using the address N8:0. In order to interface with
database base register 405, the remote master would use the address N9:5. The
following table outlines the complete file emulation for the module:
Register Range File Start File End Content Size
0 to 4999 N7:0 N31:199 User Data 5000
5000 to 5009 N32:0 N32:9 Backplane Configuration 10
5010 to 5039 N32:10 N32:39 Port 1 Setup 30
