Stop Logging / Trends in 800xA ver. 4.1

Is it possible to stop logging / trends in 800xA ver. 4.1 in order to look them for longer period?

The system has no additional History services (IMS) included, only integrated in 800xA Base History.

The trends/logs are configured now for 1 month period.

Due to process trouble, the production line is stopped for longer period - e.g. 3 months. Actually there are no new "real" records for the trends, but the time is going on, and after 1 month the logs/trends will be overwritten by the actual values. It will not be a possible to analyze the trends at the moment of trouble.

Is there any way, different from copy to Excel, to look the trends for longer period? Or to save them (not by print screen)?

If configure the logs for longer period, the old data is cleared.

Same is with alarms - they are already overwritten by new alarms - the maximum number (10'000) is already reached.

Unlike many of its "competitors" Basic History allows for runtime change of more or less all parameters there are to tune&tweak. Hence, you can easily change log period from 1 month up to a year or two (if disk space allows; 24 bytes disk space per log entry is required). Keep total storage less than 50 GB.

If a secondary log with averaged data, e.g 1 minute is acceptable you can simply add the secondary log to the template, online. Again, keep the total storage volume below 50 GB. Large configuratons of Basic History benefit from a simpler log hierachy with just one or two secondaries.

A backup of Basic History data (or a copy of its data folder, taken when service is offline) can be interpreted manually using the AdvHtLogDataViewer.exe tool.

Theoretically, the history backup can be restored into a clone of the system and viewed there. A lot can be accomplished with today's tools (VMware runtime converter standalone, VMware Player, et.c)

Event Storage can be tuned to store more events. Up to 50.000 events per category following the user's guide, maybe a bit more if the customer accepts less performance in event lists.

There are several "event loggers" available on the 3rd party market. I recommend using the OPC AE interface over a logger using some serial port emulator in combination with the Alarm Logger service.

Many thaks !

- Secondary Log is a good idea, but I have to go on site, the customer couldn't handle that. I'm quite sure the original logs remain unchanged

- I will try with AdvHtLogDataViewer.exe but not quite sure how to create then the empty system. You wrote "theoritically, backup can be restored...""

- 3-rd party OPC AE I use already in other projects, just with that customer don't have such.

If you, e.g. clone aspect server 1 and put that clone in a VMware Player you can easily:

a) Remove System + restore latest backup to "prove" backup to be good

b) Restore Basic History backup (or just unzip a copy of the \OperateITData\BasicHistory folder) to permit viewing of the trends contained in the backup, regardless of present time.

AdvHtLogDataViewer.exe is an offline tool - files must not be in use by any process (I also believe that in some version they have to be *NOT* Read Only).

Forgot to mention that you should change security from domain to workgroup if you go for a "laptop" system. Change service account after Delete System but before Restore Backup.

Hi Stefanm I managed temporary the problem - just extend the period of logs in Library Templates, fortunatelly they are totaly 2 used.
There are only 2 non redundant servers - separate connect and aspect. No domain installed.
Could you please advise how to clone the aspect server - I have a licensed Acronis 2015 for example. Then how to put that cloning in VM? From my experience Acronis is doing offline image of the disk/partition

Forgot to say - changed log template by telephone :-) it is a good customer

Last, I mentioned your advise for using of VMware runtime converter standalone. I will try it soon. Thanks !!!

I'm no pro on Acronis nor VMware, but making a clone to run in some laptop or other machine should not be such a big problem.

Acronis image method is preferred since you take the backup image offline.

Later, you should be able to convert or load that image into VMware Player (freeware) or VMware Workstation (licensed) or any other virtualization solution (eg Hyper-V from Microsoft).

VMware Runtime Converter Standalone creates an image directly suitable for VMware.
