Hello Taher; I hope I am answering your question correctly for your project. Step 7 has an accompanying package called S7-Graph, that allows programs to be developped in IEC 61131-3 SFC (Grafcet) language; this language was designed for sequential function programming. On the Siemens Controler portal you can have a very good introduction to the language, and links to more material: You can purchase S7-Graph either as a single add-on to Step 7,

Standard Functions SFC0 (SET_CLK) and SFC1 (READ_CLK) are available in Step 7 to write/read the system clock on the S7 CPUs. Here is a FAQ that will guide you in the use of SFC1: http://support.automation.siemens.com/WW/view/en/21222026 Hope this helsp, Daniel Chartier |
