Extended know-how protection
Besides the "standard" Know-how protection the CPU from VIPA provide
an "extended" know-how protection that serves a secure block protection
for accesses of 3
rd
persons.
The standard protection from Siemens transfers also protected blocks to
the PG but their content is not displayed. But with according manipulation
the Know-how protection is not guaranteed.
The "extended" know-how protection developed by VIPA offers the
opportunity to store blocks permanently in the CPU.
At the "extended" protection you transfer the protected blocks into a WLD-
file named protect.wld. By plugging the MMC and following overall reset,
the blocks in the protect.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
header are loaded. The source remains in the CPU and is thus protected
for accesses of 3
rd
persons.
