What is your setup? Is this a new project you are trying to set up or just an extension and other displays run already well on PGP?

We have Ac 800 F and using power generation portal installed at D Drive.The problem is the Size of History backup folder increase with in 7 or 8 days and no space on disk to handle next entry.The system gives low space memory and field values becomes pink in color,means no values of any parameter.in such case the graph also does not shows values .
In such situation we manually cut the files from history backup and paste them on external drive leaving 3 or 4 last files.by doing so all parameters and graph trend appear. But this time no graphics trend displays. Others parameters behaves normal. Plz also tell me about automatic transfer of files from history backup folder.

Dear Azam Khankhail ,

I assume the trends in graph were working and now they are not showed any more. It could be a playback data corruption, to correct this situation you show follow the below steps:

Stop the PGP Server
Run the PBSHOW.EXE utility you will find inside the PGP bin folder
Go to "Playback Archive" section
Select DeleteAll feature
Restart the PGP server

This action will cleanup the playback archives in that server (all playback data will be lost) and you restart your data archiving from scratch, I would expect trend to work again.

Best Regards
Mauro Casalini

Thanks for your suggestions and guidelines. I have one question before doing this. Any affect on plant by stopping PGP server because power plant generating 72MW at that time.

If you have a redundant system, maybe a pair of servers, you will run with only one server for the time requested to complete the action and the server restart. If you have one server only you definitely have to wait for a plant shutdown.
Obviously everything must be approved by your customer.

Hi, I have two operator station only one operator station have PGP server. Any other method or option to handle this on urgent basis. It is raining here and in April we have demand of full load.

First, looking to the logs, you should try to find the root cause of the issue, I suspect the playback but it could be another. If the playback issue is confirmed I cannot see so much it could be done without a shutdown of the server, I'm wondering why if this plant is important they didn't buy a redundant system, in any moment you could experience a failure and they will be blind.

Looking to logs I can confirm the issue is a corruption of the playback files, so the procedure to follow is the one indicated.

Hi, no if you start the pbshow.exe utility on the server you will have a menu (even an icon to select it) to go to Playback Archive section, there you will find the Delete All command
