Dear JuanZetaB The structure of S5TIME in S7 controllers is similar to the structure of defining time values for timers in S5 controllers."S5T#" informs the PLC to arrange the data in form as described in the attachment.

Hello Juan; Hdhosseinihas answered your question very precisely, and there is no need to look elsewhere for any esoteric explanation. Before the S7 family of PLCs, Siemens produced a line of S5 controllers. Their programming software (Step 5) used timers in a format explained in Hdhosseini's post. Siemens decided to use the same format in their basic Timer instructions in Step 7, so S5 programmers would feel at ease with the S7 platform (Siemens also introduced the IEC timers in their Step 7 librairies, and they are much easier to use in my opinion). So S5T#... simply means timers of the S5 variety. Hope this helps, Daniel Chartier |
