Memory Card Files
Communications Unit settings, BASIC Unit memory switches, and custom-
ized settings (function codes and data areas).
2. The files that will be transferred at start-up must be named "AUTOEXEC."
3. Files called BACKUP are created when the simplified backup function is
used. Refer to 1-13-4 Upgraded Specifications for details.
There are two methods for automatic transfer of files at start-up:
1. When pin 5 of the CPU DIP switch is ON, the Extended PC Setup file (AUTO-
EXEC.STD) and the program file (AUTOEXEC.OBJ) are both transferred to
Program Memory at start-up. If either of the files is missing, a memory error
will occur and neither file will be transferred.
2. The PC Setup can be set (setting D, Program Transfer at Start-up) to trans-
fer the program file (AUTOEXEC.OBJ) from the Memory Card to the PC au-
tomatically when the PC is turned on. In this case the extended PC Setup file
(AUTOEXEC.STD) is not transferred.
With either method, the transfer will not proceed if the write-protect switch is ON,
but will proceed even if the program memory access right is restricted from the
CVSS/SSS. The transfer normally takes about 4 seconds.
To enable file transfer at start-up, the proper files must be recorded on a Memory
Card in advance from the CVSS/SSS. The Extended PC Setup file (AUTOEX-
EC.STD) can be transferred directly from the PC to the Memory Card in online
operations from the CVSS/SSS. The program file (AUTOEXEC.OBJ) can be
created on the Memory Card using one of the following two operations.
In online operations, transfer the program and other files to the PC and then
transfer the program file to the Memory Card from the PC.
Convert the program into an object file in offline CVSS/SSS operations, and
then transfer it directly to the Memory Card in online operations.
If the PC is set to transfer the program at start-up but the transfer cannot be com-
pleted for some reason, the Memory Card Startup Transfer Error Flag (A40309)
will be turned ON, a memory error will occur, and the PC will not begin operation.
When the program is not transferred, either find and eliminate the cause of the
error or change the PC settings so that the program won't be transferred, and
then turn the PC off and on. The following are possible reasons that the program
cannot be transferred:
The write-protect switch is ON.
One or both AUTOEXEC files are missing.
The Memory Card power is OFF. (If the M/C ON indicator is not lit when the PC
power is ON, press the Memory Card power switch.)
The Memory Card is not installed.
It is not possible to write to an EPROM Card installed in the CPU. Use the
CV500-MCWjj Memory Card Writer to write to an EPROM Card. Refer to the
Section 2-3
