Hi All,
I need the CPU to compare 50 bytes of data in 2 seperate Data blocks without PG online,
I couln't find anything in any standard Step 7 blocks,
I know you can compare Real,INT and DINT but need a bit more data compared.
I though of using the XOR DWORD function which will generate a value < 1 if DWORD data is not the same, then i still have to look for value < 1 than ect., and i still have to generate x-amount of merker bits to manipulate a single bit result.
Same or Not.
Must be an easier way.
Would appreciate any feedback
Kind Regards.
