Archive Data Extractor for WinCC exporting an archive, showing progress per tag

The problem

You need last quarter’s tank temperatures. Or you’re migrating a plant off WinCC. Or the system is down and all you have is a backup folder of .mdf files.

WinCC’s own export options assume a running system and a lot of manual work. Tag logging archives are stored compressed, so plain SQL can’t read them. You need the WinCC OLE DB provider, which is installed with WinCC and with the WinCC Connectivity Pack. Exporting through it from SQL Server Management Studio into Excel is limited and slow, and it’s easy to get the time zones wrong.

What it does

Reads archives wherever they are

Point it at a folder of tag logging .mdf files from a running system, a stopped system, or a backup copied from another PC. It processes every file in the folder in one run, so there’s no handling files one by one. All you need is the archive files. You don’t need the WinCC project.

Or pulls from a running project

Gets the newest values, up to now, from the open project’s runtime database. This works over the network, so you can read from another PC’s SQL Server.

One CSV per tag

Predictable file names in a year and month folder, ready for scripts and bulk loads.

Time zones done right

Enter your range in the plant’s time zone. Every row carries both UTC and local time, including daylight-saving changes.

Your layout, your columns

Choose columns, order, delimiter, and timestamp format. Add fixed-text (literal) columns, empty columns, and columns built from part of the tag name, such as a station ID. Or start from the “Bulk insert” preset for loading into a database.

Only the tags you want

Export everything, or filter with a tag list that supports wildcards. Import lists from a file.

Doesn’t disturb a live system

It only reads. Archives WinCC has attached are read in place and left attached.

Clear messages when something’s wrong

Pre-checks for SQL Server, permissions, and the WinCC OLE DB provider before touching any database, with plain advice on what to do.

How it works

Choose a source

An archive folder, where every .mdf file in it is processed in one run, or a running WinCC project.

Set the range

Date and time in your time zone. The tool shows the UTC range it will request.

Click Process

Watch progress per archive. Open the CSV files in Excel or load them anywhere.

Main window with the Archive DB folder source selected
Choose a folder of archive files, a date range and a time zone. The UTC range is shown for you.
Main window with the Running WinCC project source selected
Or extract straight from the running project’s runtime database.
Output format dialog showing columns, delimiter and a live preview
Design your CSV layout and see a live preview of the first row. Add literal text columns, empty columns, and pieces of the tag name.
Tag list dialog with wildcard entries
Filter by tag with a list that supports wildcards.

What you get

One CSV file per tag, in a year and month folder taken from your start date. Open them in Excel, or import them into SQL Server or any standard database, such as Oracle, MySQL, PostgreSQL or Microsoft Access. They also load into a historian.

Output folder in File Explorer showing one CSV file per tag
The output folder, named for the year and month of your start date: one CSV per tag. ArchiveStats.txt reports how many values were exported for each tag, and how long the run took.
An exported CSV file opened in Excel, showing tag name, UTC and local timestamps, value and quality code
Opened in Excel. Every row has both UTC and local time.
An exported CSV file in a plain text editor
Or as plain text, ready to import into SQL Server or any other database.

What you need

Just the archive files: to export archive files, you don’t need the full WinCC SCADA or WinCC Professional project, or WinCC itself. You need the archive files, a PC with SQL Server, and the WinCC OLE DB provider.

Already have WinCC on the PC? Then the WinCC OLE DB provider is already installed. Run the tool on that PC and point it at a folder of archive files. There’s nothing else to find or install. On a PC without WinCC, install the WinCC Connectivity Pack, which includes the provider and can be installed on its own.

Tested with: WinCC V7.4 through V8.1, and WinCC Professional. Not supported: WinCC Unified.

Tip: Work on copies of archives you need to keep. Attaching a file to a newer SQL Server version upgrades it permanently. The software checks first, lists any files that would be upgraded, and asks for your confirmation before it attaches them. The default answer is No, so nothing is upgraded unless you agree.

Frequently asked questions

Does it work without WinCC running?

Yes. Point it at archive .mdf files and it reads them directly through SQL Server. You don’t need the WinCC project, only the archive files, and you point it at the folder rather than at each file. Only the “running project” source needs WinCC open.

Will it affect my running WinCC system?

It only reads data. It never detaches or changes archives that WinCC has attached. Very large exports add load to the SQL Server while they run, so schedule those sensibly.

Does it change my archive files?

No data is changed, but attaching a file to a newer SQL Server version than the one that created it upgrades the file. If the archives must go back into an older system, export from copies.

Where does my data go?

Nowhere. The tool runs on your PC and writes CSV files to a folder you choose. It doesn’t send archive data anywhere. Licenses are checked on the PC and never need an internet connection.

What’s in the CSV?

By default: tag name, UTC timestamp, local timestamp, value, quality code. You can change the columns, order, delimiter, and timestamp format.

Why do the two timestamp columns look identical in Excel?

Excel hides the date and hour on times with milliseconds. The data is intact. The User Guide shows the one-line custom format that displays it properly.

Can I export from a WinCC PC over the network?

Yes, with the Running WinCC project source. Enter the other PC’s SQL Server, for example WINCCPC01\WinCC, and you can read its runtime databases from your own PC. You need Windows access to that SQL Server, and the WinCC OLE DB provider must be installed on the PC you run the tool on.

The Archive DB folder source doesn’t work over the network, because SQL Server opens archive files from its own disks. Run the tool on the PC whose SQL Server holds the files, or copy the .mdf and .ldf files to a PC with SQL Server and the WinCC OLE DB provider. For other setups, contact us.

Which license do I need for a one-time migration?

A Project Pass covers 30 days of use by one person.

I’m an integrator. Can I use it at customer sites?

Yes. Each person on your team needs a seat, and a seat can be used on any computer, including your customers’, for work that person is doing. See the Integrator Pack.

What happens when my update year ends?

Nothing stops working. You keep every version released during your update period. Renew if you want newer ones.

What if it doesn’t work with my archives?

Please try the free trial first to check compatibility. If you’ve bought a license and it doesn’t work with your archives, email us. If we can’t fix it, we’ll refund you. See the Refund Policy.

Is this affiliated with Siemens?

No. Archive Data Extractor for WinCC is an independent product of iQagent. It works with archives created by Siemens WinCC.

Can I get it to run automatically on a schedule?

No. It’s a desktop application you run when you need an export. It isn’t designed to run unattended or on a schedule.
