Hi razoh,
what do you means with "Historian": a different station lice "Stoareg Plus", "CAS" or "Simatic IT - Historian"? only "Operation List2 disappear when you download on the server or "all message list" and "historical trend"? anyway, if you configred in right way the historical data: 1) alarm historichal data: open Alrm logging, select Archive Configuration, right click on Message Archive ans select properties then configure segment data for historichal 1) trend historichal data: open Tag loggingogging, follow the above procedure for both Archive (Fast and Slow) During OS download (doesn't matter if complete download or change only) only configuration data are downloaded, no online data. That means you don't have to loose any historichal data untill you delete manually. Last question: did you run OS project in runtime over Engineering station? is yes, look for this FAQ
Hope can help Regards |

Yes my Historian is a different station, actually is a CAS. I have 8 different stations: EWR, 2 Redundant Servers, CAS and 4 Clients. I think there is a problem with the alarms archive configuration. I am sure that the trend archive is Ok because I can get data even from October last year, but is not happening the same with the alarms. It seems the alarms are not being saved on the CAS, but I am not sure. I have attached printscreens of the Alarm logging configuration in the CAS and in the Server, perhaps that information can be useful. Also, my knowledge about the Alarms configuration, alarms logging and CAS Configuration is quite poor as I have never done that king of configuration, could you advise me any manual or tutorial to check that everything is ok.

Hi razoh , i'm so sorry but...i'm not able to understand yor configuration. I'm going to gess following, you posted: - "Alarm Loggin Server" for Redundant Server Stations - "Alarm Logging HIST" for CAS what follow is relevant if i supposed right - redundant Server keep data for "2 Hours or 1GB size" for all segment (after that older data will be overwritten). In this case you can see alarm for last 2 hours (no older) - CAS Station doesn't need Alarm Logging configuration (CAS need WinCC instance installed but not configuration)...so, that's the reason i said i don't understand your configuration You have to look for CAS configuration in Windows Button Start->All Programs->Simatic->Storage Plus->Administration Consol. You should be able to find documentation in online manual installed with CAS installation, or in PCS7 Documentation in depends on your version Anyway, if you can see file *.ldf & *.mdf in "ArchiveDir" on the CAS station, then disappear, means CAS station is working fine and storing data. If not, something wrong in WinCC server configuration. Is file are stored in CAS folder and you can't see alarm on CAS station, means something wrong is over CAS station. Try to check where is the trouble, then give more info if need more help Hope can help Regards |

Hi Cbo, I also think that hardware configuration in not correct on CAS because there is nothing in the "Station Manager" but as you can see in the files attached, data is being recorded. It is quite obvious that data is being recorded in both Redundant Servers and CAS, but I am not able to see the alarms for example that came two months ago. In this case it seems the clients only show that from the servers. But....I dont have that kind of problem with the TagLogging, I can see values of tags since the first day I archived them. Any idea Thanks

Hi razoh , i'm still confused about your project configuration. The right configuration should be: 1 - Redundant server with Alarm Logging/Trend Loggingconfiguration for all time you need 2 - CAS configuration (it want WinCC install instance) without WinCC graphic runtime 3 - Configure PCS7 Alarm/Trend to archive data to "archive" folder on the CAS station. In this way it possible to see online trend on the Server/Client and ALL historical data on the CAS station (using Storage Pluc Viewer) In addition it possible: 4 - share "server data" from CAS to PCS7 station to be able to see CAS data from them 5 - configure IE browser on PCS7 to use station like Client for CAS here a link for CAS manual & configuration
Hope can help a lil Regards |

Hi razoh,
I'm still confused about your configuration. Typical confugration is: 1 - OS server store data locally for short historychal (1 month for example): you can display these data from Trend Control Object into WinCC graphic display from OS Server & OS Client 2 - OS CAS has to be configured into your project but not tag logging into CAS has to be configured 3 - Configure Tag Logging in OS Server to backup data into OS CAS archive shared folder 4 - Configure Stirage Plus Administration, Storage Plus Editor View & use Storage Plus Viewer to dislay ALL stored data (data from when CAS started) 5 - In OS Project Station, Servers and Clients, confgure Server Data coming from OS CASto display ALL historychal data Hope can help Regards |
