I don't think this is the place and I certainly don't have the time to type the info you're requesting. The answer to this question is to be found in the S5 manuals. These are all available at the Siemens website. I don't have the address at hand, but I'm sure you can find the links to various S5 manuals if you search this forum.nhot100 said:would you please help me tell me a description of s5 plc details and specification?
That's entirely depending on the tasks you want the PLC to perform. If you want to program a sequence, you might turn to sequential function charts (aka grafcet) or dynamic state diagrams. For the design of calculation programs, I find flowcharts and Nassi-Schneidermann diagrams better suited.nhot100 said:and what is the best way in programming technique?
