Dear Jamil_paki, Yes, you can start with CPU313C. Then you can use Step7 lite. You can download herefor free When you want to use Profibus or Profinet etc. you can decide to use another CPU and buy Step 7. Best regards, Wizard |

313C is good, but if you want PROFIBUS addition, I recommend the 314C-2DP.
STEP 7 has a PLC simulator, called S7-PLCSim, is very good. |

Hello Jamil; If you do not plan on networking (Profibus or Ethernet) then yes Step 7 Lite is a very good package. It was developped originally for OEMs whose core market was more single machines rather than plants, so networking capacities were stripped. No Netpro (communications connection editor), co CPs in the hardware catalog. But the instruction list is the same (outside of communication blocks) and the programming languages and techniques are similar to the Step 7 basis package (no SCL or Graph packages support, though). So you will get a good feel for the whole package and good practice. And yes, there are upgrade licenses available from Lite to Step 7, so you can move up to the standard license at a better price later. Two more differences you might want to look ast: Step 7 Lite works under XP Home edition (no Vista support yet) while Step 7 Basis requires a XP Pro version (or 2000 Pro, Vista Ultimate); and the save format of the Lite projects are not the same as Step 7 program; they are incompatible, but there is an import/export procedure that will allow a Lite program to work in Step 7, and vice-versa. Here are some FAQs that give more details: http://support.automation.siemens.com/WW/view/en/31031123 http://support.automation.siemens.com/WW/view/en/22586862 http://support.automation.siemens.com/WW/view/en/22587065 Hope this helps, Daniel Chartier |

I think you will need a guide beside the kit you will order. I do recommend to contact Sitrain for attendance of training course and also have a look on the following links. You will see a basic training in aflash filesand I think it will help you. http://support.automation.siemens.com/WW/view/en/21064133 http://support.automation.siemens.com/WW/view/en/21062590 http://support.automation.siemens.com/WW/view/en/21043576 |
