Hello rajib I'll try to answer your questions: (1) How I can connect S7 300 PLCs to CP 5613 card? --> Via Profibus Cable and Profibus plugs (2) How can I use Profibus DP protocol to retrieve and transfer data between PLCs and PC? --> You would need to configure your S7 300 CPU's as DP Slaves ofCP5613 (which is the DP Master) and could then exchangeup to 244 Bytes of data between each CPU and the PC. I would however NOT do this and NOT use Profibus DP protocol for this purpose. Instead I suggest you use so called S7 communications (via Profibus or MPI or Ethernet) for the data exchange between the PC's HMI application and the S7 CPU's. (3) For GUI, can I use WinCCflexible or some other SCADA Tool? --> Absolutely and WinCC flexible would be my first choice for you. (4) In which platform I have to write the data transfer programs? --> Assuming you use WinCC flexible, you'll simple configure the connnection (decide if it is Etehrnet, Profibus etc.), configure/link the tags and that's basically it (you don't "write" a data transfer program in this case) (5) Can I write the data trasfer programs in Simatic manager Step7? or I have to write in VC+ or VB/.NET --> See answer above 6.) CAN YOU GUIDE ME TO FIND SOME SAMPLE PROGRAMS OR suggest some links where I can find the sample programs --> Here are some links which will hopefully help Screencast Tutorial: Visualization - The HMI Integration WinCC flexible Manuals Simatic Net Quickstart CD Last but not least: Why do you want to use a CP5613 for the link between the PC and PLC (it seems "wastefull" and a CP5611 would suffice for this)? Should your S7 CPU have an onboard Profinet port you could also ditch the CP all together and use the Ethernet port of your PC. I hope this helps to get you started and good luck. |
