We got a offer from a siemens supplier - S.No. DESCRIPTION Make QTY 1 CPU 315-2DP Siemens 2 2 MMC 128KB Siemens 2 3 RAIL, 160MM Siemens 2 4 P.S. 5A Siemens 4 5 PS 10A Siemens 1 6 Redundancy Bundle Siemens 2 7 Active Rail Siemens 2 8 Active Bus Modules Siemens 6 9 16 DI Siemens 2 10 8DO Siemens 2 11 8 AI Siemens 6 12 8 AO Siemens 2 13 40 PIN FRT.CONN. Siemens 8 14 20 PIN FRT.CONN. Siemens 4 15 Profibus conn without PGI Siemens 4 16 Profibus conn with PGI Siemens 2 17 Profibus Cable Siemens 400 18 WinCC 128 Run Time Siemens 2 19 CP5611 Siemens 2 20 Step 7 Basic Package V5.4 Siemens 1 21 Control transformer Reputed 1 22 MCB DP 4 A for traffo i/p Siemens 1 23 MCB DP 6 A for traffo o/p Siemens 1 24 Fan with filter 6'' 220V Reputed 2 25 Illumination light 20W 220V AC Reputed 1 26 Door switch Reputed 1 27 MCB SP 2A for cooling fan & light Siemens 1 28 Cabinet Rittal Make 1 29 PC with cabinet/consol Reputed 2 I want to know that this system is ok can i got both redundancy (HWR & SWR) in this CPU. if i got only software redundancy what will be the loss in this. as per my opinion i need both SWR as well as HWR . Please suggest me.....................

Hello mohit;
I cannot say about the hardware section, this you would need to check out by yourself, possibly using the Simatic Hardware Configurator from the Industry Mall:
https://eb.automation.siemens.com/goos/WelcomePage.aspx?regionUrl=%2fuk&language=en

- You will need a few WinCC Flexible licenses to operate a Runtime application. Start with the following manual that will explain the different licence levels and their application:

http://support.automation.siemens.com/WW/view/en/18796010

6AV6613-0AA11-3CA5

WINCC FLEXIBLE 2008 ASIA ADVANCED, ENGINEERING-SW,FLOATING LICENSE SW AND DOCUMENTATION ON DVD LICENSE KEY ON USB STICK SW AND DOCU IN EN/CHS/CHT/J/K EXEC. UNDER XPPROF/ WINDOWS 7 BUSINESS/ULTIMATE/ ENTERPRISE (32 BIT), FOR CONFIGURATION OF SIMATIC PANELS AND WINCC FLEXIBLE 2008 RUNTIME

You will need to select your Runtime license based on the number of tags you will be using in your project. Look at the different licenses available here:
https://eb.automation.siemens.com/goos/catalog/Pages/SearchResult.aspx?search=wincc%20flexible%20runtime&exact=n

- You will also need the Software Redundancy package for S7-300(and manual):
http://support.automation.siemens.com/WW/view/en/1137637

6ES7862-0AC01-0YA0

SIMATIC S7, SW REDUNDANZ V1.2 SINGLE LICENSE F.1 INSTALLATION R-SW (FOR TWO CPU), SW AND DOCU. ON CD, CLASS A,5 LANGUAGES(G,E,F,I,S), EXECUTABLE UNDER WIN95/98/ME/ WINNT/2000PROF, REFERENCE-HW:SIMATIC S7-300/400 FROM CPU 315

Note one more point: I am not sure how the Software Redundancy will be used with a WinCC Flexible Runtime licence: whether you willneed to have two distinct stations, each with their licewnses and CP 5611... I hope someone with more information on the subject can add something here.

Hope this helps,
Daniel Chartier

I hope someone with more information on the subject can add something here Each station should have its own license and its own CP5611. 2- I hope you haven't forgotten your redundant link. It seems to me that you will build your redundant link over MPI and you will also use this subnet for communication with PCs, correct me if I'm wrong. It will work but you may suffer from slow communication over MPI. However, I don't think it will be a big problem since your project is relatively small. 3- You can use only one Red. bundle if you like. The IM153-2 HF supports up to 12 modules. 4- Check the numbers and types of Profibus connectors. I think you need4 more (2 for the PCs. and 2 for MPI ports on CPUs) Best regards. H-H

I want to know that this system (EDIT: Software redundancy based S7-300 system) is ok. if i got only software redundancy what will be the loss in this. as per my opinion i need both SWR as well as HWR . Hello mohit I can't tell you if a SWR (Software Redundancy) based system is good enough for your "very critical process" or not, I can tell you though that its redundancy is limited to the CPU's and the (Profi)bus (NO redundancy on the I/O level possible). If you can NOT tolerate process downtime (which is the message I'm getting from your post) a "High availability" S7-400 H system with (some or all) redundant I/O's would be the wiser (albeit dearer) choice. Hot swap support and being able to integrate safety into it are some other main benefits that set a S7-400H system apart from its Software redundancy based "poor cousin". I hope this helps
