[?+]: "Problem" with s5/s7 software

[BLima]

Hi,

Does anybody have a table with the addresses of the major special marks bits of S7 PLC - CPU 312?

I am looking for the bit that goes to "1" in the 1st cycle, after the order to run the program.

I tried setting SM0.1, has for the S7-200 series, but without result.

Regards,
Bruno
