I just started this PLC thing like a hobby for 2 weeks ago, i started with Mitshubishi gx developer.
I think i have sit around the computer for 2 days try to figere out how to use counter in S7-300 and i still dont understand.
i just want to count to 10 then there is a signal to output it take like 3 sec with mitshubishi.
But with s7-300 some circiut look like IC with tons of input
and output CU Q CD CV S CD_BCD PV R and some weird input like S5#10s or C#12 , i have read help but still dont get it.
