not exist a crack for s5 block.
I think that you see this on the screen :
SPA M001
BE
In this case you need a plc connected to sprotect. You need also know
a initial hex address memory of block protect.
do you have a esperience with hex s5 language ?
for example the BE is = hex 65 and NOP 0 = HEX 0 .
you need to change the BE with NOP 0
download your protect block into the plc.
search the initial address of your block
search in on line mode the first HEX65 after the start address and
change in HEX00.
exit and upload the block into PG.
Now you have a sprotect block
SPA M001
NOP 0 // ex BE //
M001:rest of the code
