Hi Saravana, i suppose you already worked with Step7 and WinCC so, WinCC native and WinCC integrate in PCS7 are quiet different: 1 - don't need manually insert Tags (but just compile OS from Simatic manager, tag will be get from plc program) 2 - don't need manually insert alarm logging (same above) 3 - faceplate already ready (same above) 4 - tag logging and other feature look very similar to WinCC native very different is plc part programming: you have to program using Simatic manager but with CFC, SFC and SCL language. Everything you do on plc program prepare your WinCC database; it looks very nice but that means you have to be very clear in your mind. A quick course with your local Siemens(1 or 2 days like a presentation maybe) it will be very powerfull. Here a link just to start |

Dear Saravana, Major problems with PCS7 are: 1. U can not undo the changes. 2. Every time u must compile before downloading. 3. Many times ur changes will not be saved in CFC, i.e u make some logic in CFC and close the file and open ur logic will not be saved. 4. U must have good PC otherwise lot of patience required to work with PCS7. 5. Compilation takes more time either OS / CFC program. 6. U must need big monitor with good resolution so that it is easy for debugging and programming. Otherwise the concept of PCS7 is good. |
Thanks and Regards |

In PCS7 the CFCs look like FBD Language in STEP 7 , but with nice graphics instead of showing the addresses as in FBD language . Also it has SFCs , which looks like Flow Charts , and works accordingly. SCL language is used in PCS7 ; however you can use blocks created in STL,LAD or FBD Language in STEP7
I m not sure , but I have heard it is having bugs( sometimes your PC will hang) Unfortunately i don't have snapshots to make you understand |
