load function, so a password is required to access the mask. If the mask has been
assigned to a control key, the operator will not even know that such a mask exists.
Another method would be to prevent input by using the connected controller. The
password protection function is not required in this case. With this method, the
controller will provide data release for the mask number with the download function
only, if specific conditions set out by the user are fulfilled.
If the user does not want to make use of these options, another alternative to the
software solution via the system variable IntEraseEPROM would be to erase the
old variable definition with the aid of the user-mode switch S4. This will require
strict adherence to the routine to be executed. Subsequently the terminal will auto-
matically activate the download operating mode.
To place the operating terminal to the download operating mode:
The Flash memory is erased once the system variable has been activated. The
following message is displayed during this process:
After the Flash memory has been erased, this is indicated by the following mes-
sage:
The terminal now automatically activates the download mode and the following
message appears:
The terminal is now ready to receive a new user description via interface channel
SER2 and to store it in the Flash memory. The progress of the data transfer will be
indicated on the display by the characters ‘
.....
’, the number of characters will
therefore change continuously!
After the transfer is complete, the following message is displayed:
After the transfer, the terminal immediately starts the initialization phase and dis-
plays the startup mask of the user description.
Various error messages may appear on the display during the download or at the
beginning of the initialization phase:
ADDRESS ERROR
Error in the address calculations of the com-
piler
FLASH MEMORY FAILURE
The loaded user description contains errors or
is incomplete.
CHECKSUM ERROR
The user description contains errors, please re-
compile.
BYTECOUNT OVERFLOW
The user description contains errors, please re-
compile.
FORMAT ERROR (S0, S3, S7) Sequences in the S3 file that was transferred
contains errors.
