Thanks Ayman, for clarification.
Thanks Daniel for an explanatory post. Now CFC is clear in my mind. Just a simple question, as you have mentioned below:
If I have a Step 7, version 5.4 SP5, do I need any other software or licenses for programming a fault tolerant system? What are the default OB's and standard blocks, which I must have, is there any templete program I may get for understanding of Fault tolerant system. I am sure about, we are doing a Fault Tolerant system, but still would discuss with Distributor why he gave us the quote and hardware for Fail Safe System. I think, we may save huge sum of $'s just by using the right hardware. |

6ES7833-1CC00-6YX0is just to verify by visual inspection of the controller that that CPU has Fail safe program. It's scope of supply contains a hardcopy certificate if I remember well and two nice small TUV stickers. You have to stick one for each CPU. That all you will found in the package. Hope this helps. Hello Ayman, Sometimes i don't understand why siemens make things so secret like this one so that no one can eaisly realize!! Does it make any sense to have separate MLFB just to have certificate and two stickers. May be i am wrong but it should be part of failsafe system by default. I think Separate MLFB with software discription creates confusion. I was also not aware of this but thanks for information.Hello Amit_86, You are right. But I can not help you as I do not understand why Siemens make this secret. When you read the description of that product, you will never know the you will recieve just one hard copy certificate + 2 yellow TUV stickers.

Lucky123 In my opinion, you are very difficult to formulate a question. I tried to clarify it in the first post, but here there was a lot of text, and I with my bad English in general has lost the thread of discussion. I agree that the FH-system is difficult to understand - why it should be, for what it is necessary. But somehow I received a simple understanding of the difference between these systems: H-system - as long as possible without stopping the process, FH-system - how to stop the process more reliable. At the same time both systems (H and FH) are redundant, But as you can see, they are fundamentally different. In the F-CPU license key is included. Therefore, additional licenses are not required. In the H-CPU F-Software is absent, and must be purchased separately. which in fact is a license for F-blocks. Tool software requires licenses ever, because it is not included in Step7. Perhaps in the future it will become part of Step7, and will not require additional licenses. Previously, H-design tools and systems purchased separately and require separate licenses - (maybe this has caused your question?). But now, now, starting with the Step7 5.3 it does not require. |
