Dear Experts, I have worked on some of the Siemens S7 300 and 400 Systems, and I have S7 Version 5.4 SP5 installed on my machine. However, this time I am working on a new project which is S7400H redundant system, and Siemens Distributor has advised for the below licenses to be purchased in order to work on that system. All the licenses which have been quoted are mentioned below: For my sake of understanding, I would like to know, what is the purpose of all these licenses, and can not I just do the hardware configuration and write the code in the software S7version 5.4, SP5 which I have. What problem I may face if I do not buy these licenses or ask my client to buy these. Would these licenses require just for testing the system or these are must for hardware configfuration and coding also? Please also let me know, if I can much more details of usage of these licenses, and what are the CFC blocks? Why do we need them, can I write CFC blocks without buying these licneses? Also let me know, what are the default blocks which I must have in the program. A detailed response, would be highly appreciated.

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 Lucky;
I am a bit confused at this time on the quality of the respons e from the distributor. You say in the quote above thatyou want to use a S7-400H system (redundancy between 2 CPUs); the distributor seems to have given you a list of licenses for the S7-400F system (failsafe CPU). Please look at the following information, collected from different siemens sites, and confirm what type of configuration you wish to do, so we can clarify our own answers: Failsafe CPUs: S7-400F DescriptionThe fail-safe SIMATIC controllers are available for ensuring the functional safety of machines or plants. They meet maximum safety requirements and thus facilitate compliance with relevant standards: EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3, and EN ISO 13849 up to PL e.As standard and safety programs can be processed simultaneously, only one CPU is required to carry out both tasks. SIMATIC Industrial Software S7 F/FH Systems - Configuring and Programming SIMATIC Industrial Software S7 Distributed Safety - configuring and programming Fault-tolerant CPUs (High-Availability): S7-400H Description Risk factors such as power outages, water damage, fire outbreaks, or lightning strikes, but also system failures or operator errors, can significantly affect the operation of a plant, as far as plant downtimes. This is where redundant systems come in. The fault-tolerant system environment ensures protection against system failure and helps you to increase your productivity to a maximum by sharing the user program between 2 PLCs: a primary and standby CPU.

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.

Daniel, Thanks for your response. The hardware items for this project is on the below post. I would go back and check with my distributor for the clarity on this. In the mean time, if you can please check the above thread and see the hardware suggested and the software licneses makes sense to you. Thanks for all your help. |

Hello Lucky; As per your last post: what are CFC blocks. Here is a definiton of CFC charts common to both of the following manuals: What is CFC? CFC (Continuous Function Chart) is an editor with a graphical user interface, an extension based on the STEP 7 software package. It is used to create the entire software structure of the CPU and uses pre-configured blocks. The editor lets you insert blocks into function charts, assign block parameters and interconnect blocks.Interconnecting means that values can be transferred from one output to one or more inputs during communication between the blocks or other objects. Look at the following manuals: SIMATIC CFC for S7 Continuous Function Chart V6.0 SIMATIC Process Control System PCS 7 CFC for SIMATIC S7 And in the attached illustration you will see a typical CFC chart |
