Hi, I am new both here and in programming Step5. I am looking for literature on the basics of programming step 5 , particularly the FBs, nd DBs,DWs nd how they are addressed and what they influence as well as timers, counters, latching relays, etc. I have visited the siemens support website and downloaded some literature from their, but the description of the FBs and DBs and timers is very vague. Could someone help me with a more detailed description of these functions. Thank you in advance.
