Rockwell Automation 2706-LSW DL40 PLUS OFFLINE PROG.SFTWR.USER MANUAL - Manual (Page 24)

2–2 Installing the Software
Publication 2706-6.2
After installing the software, your computer will contain a
DL40.EXE as well as a PS.HLP file containing online help. If you
install the PassThrough capability, you will also have the
PassThrough files and their companion TSR (Terminate and Stay
Resident) server files.
Important: For the Offline Programming Software to operate
without generating warning messages about memory limitations,
your computer needs a minimum available memory of 570K RAM.
Editing a 128K message file requires the full 570K. Smaller
message files require less computer memory.
With DOS versions prior to 5.0, use the CHKDSK
↵
command at
the DOS prompt to determine the available conventional RAM on
your system. The available conventional RAM will be reported in
bytes. Your system must have 583,680 or more free bytes RAM to
run the Offline Programming Software and edit large application
files.
With DOS versions 5.0 or higher, use CHKDSK
↵
or the MEM
↵
command to accomplish the same task. (The MEM
↵
commands
reports more quickly and in greater detail than does CHKDSK
↵
.)
The value reported for free conventional memory must be at least
570K.
The following table provides RAM recommendations for creating
and editing message files and requirements for using PassThrough.
If your computer has less than the required bytes free, reduce the
number of memory resident programs (communications programs,
mouse drivers, etc.) your computer is running. For additional
information on increasing the amount of available memory, refer to
the configuration section of your computer’s DOS manual.
