Simatic gimmick again fellows !

WITH the SIMATIC S5, compression of the internal program memory of the PLC is not allowed when an OP is connected...
OP-panel uses direct memory access and it reads PLC's memory in start-up.
When Simatic-S5 programmer compresses memory, could DataBlocks and plc-programs go to different palceses f.e. some program can go to memory-area where some DB was earlyer. If OP-panel up-dates data to that DB, data goes to prgram-code !!!!!!!!!!!!!

I don't know, work they all other OPs on same kind ???
