To the following times an access takes place on a storage medium:After overall resetn The CPU checks if a VSC is inserted. If so, the corresponding optional functions areenabled.n The CPU checks whether a project S7PROG.WLD exists. If so, it is automaticallyloaded.After PowerONn The CPU checks whether a project AUTOLOAD.WLD exists. If so, an overall reset isexecuted and the project is automatically loaded.n The CPU checks whether a command file with the name VIPA_CMD.MMC exists. Ifso the command file is loaded and the commands are executed.n After PowerON and CPU STOP the CPU checks if there is a *.pkg file (firmware file).If so, this is shown by the CPU by blinking LEDs and the firmware may be installed byan update request.Ä Chapter 4.13 ‘Firmware update’ on page 76Once in STOP staten If a memory card is plugged, which contains a command file VIPA_CMD.MMC, thecommand file is loaded and the containing instructions are executed.The FC/SFC 208 ... FC/SFC 215 and FC/SFC 195 allow you to includethe memory card access into your user application. More can be found inthe manual operation list (HB00_OPL_SP7) of your CPU.4.16 Extended know-how protectionBesides the "standard" Know-how protection the CPUs from VIPA provide an "extended"know-how protection that serves a secure block protection for accesses of 3. persons.n Standard protection– The standard protection from Siemens transfers also protected blocks to the PGbut their content is not displayed.– But with according manipulation the know-how protection is not guaranteed.n Extended protection– The "extended" know-how protection developed by VIPA offers the opportunity tostore blocks permanently in the CPU.– With the "extended" protection you transfer the protected blocks to a memory cardinto a WLD-file named protect.wld.– By plugging the memory card and then an overall reset the blocks in the pro-tect.wld are permanently stored in the CPU.– You may protect OBs, FBs and FCs.– When back-reading the protected blocks into the PG, exclusively the block headerare loaded. The block code that is to be protected remains in the CPU and cannotbe read.1. Create a new wld file in the Siemens SIMATIC Manager with ‘Fileè Memory Card file è New’.2. Rename the wld file to "protect.wld".3. Transfer the according blocks into the file by dragging them with the mouse fromthe project to the file window of protect.wld.4. Transfer the file protect.wld to a memory card.Accessing the storagemediumOverviewProtect blocks with pro-tect.wldVIPA System MICRO Deployment CPU M13-CCF0000Extended know-how protectionHB400 | CPU | M13-CCF0000 | en | 16-47 81
