Create a new wld-file in your project engineering tool with 'File è Memory Card file
è New' and rename it to "protect.wld". Transfer the according blocks into the file by drag-
ging them with the mouse from the project to the file window of protect.wld.
Transfer the file protect.wld to a memory card, plug the memory card into the CPU and
execute an overall reset with the following approach:
The overall reset stores the blocks in protect.wld permanently in the CPU protected from
accesses of 3. persons.
Protected blocks are overwritten by a new protect.wld. Using a PG 3. persons may
access protected blocks but only the block header is transferred to the PG. The block
code that is to be protected remains in the CPU and cannot be read
Protected blocks in the RAM of the CPU may be substituted at any time by blocks with
the same name. This change remains up to next overall reset. Protected blocks may per-
manently be overwritten only if these are deleted at the protect.wld before. A factory reset
does not affect the protected blocks. By transferring an empty protect.wld from the
memory card with an overall reset, you may delete all protected blocks in the CPU.
Due to the fact that reading of a "protected" block from the CPU monitors no symbol
labels it is convenient to provide the "block covers" for the end user. For this, create a
project of all protected blocks. Delete all networks in the blocks so that these only contain
the variable definitions in the according symbolism.
A Command file at a memory card is automatically executed under the following condi-
tions:
n
CPU is in STOP and memory card is plugged
n
After each PowerON
The Command file is a text file, which consists of a command sequence to be stored as
vipa_cmd.mmc in the root directory of the memory card. The file has to be started by
CMD_START as 1. command, followed by the desired commands (no other text) and
must be finished by CMD_END as last command.
Text after the last command CMD_END e.g. comments is permissible, because this is
ignored. As soon as the command file is recognized and executed each action is stored
at the memory card in the log file logfile.txt. In addition for each executed command a
diagnostics entry may be found in the diagnostics buffer.
Please regard the command sequence is to be started with CMD_START and ended with
CMD_END.
