Create real Excel files with a Siemens PLC

The days when you and your customers tormented yourself with CSV files are finally over: Our software reads and writes real Excel files (xlsx).

PLC trend evaluation with Excel

Design Excel templates according to your wishes. Logos, formulas and everything else Excel has to offer. And if you don’t want or need the luxury of real Excel files: Our software supports CSV as well.


Excel chart

Present important data in diagrams and charts. Use the power of Excel and show important information in pie charts, line charts or other charts. All diagrams can be included in Excel templates.

Your PLC controls everything

Due to our innovative trigger concept, the PLC has all power. The S7 makes the decision which Excel data should be read or written. Furthermore, you  have the  full flexibility when writing the Excel file. You can design the logging cell by cell, line by line or block by block. Configuration remains very simple thanks to our clear program interface.

Also possible: Trigger at the push of a button

You do not want to start the triggers from your S7 program – no problem. You can also start all triggers directly from our program. A simple visualization allows the machine operator to load Excel files into the machine or to create an Excel protocol at the push of a button.

You can release each created trigger individually for the machine operator interface. The settings can optionally be protected by password. This is what we call full control and simple operation.

Our customers range from industrial groups and medium-sized global market leaders to small businesses.

PLC simulator and live data view

Thanks to the integrated simulator, you can also configure our software without a connected PLC. This allows you to prepare and test the configuration in advance before you go to the plant.

The live data view shows you the currently read PLC data blocks live. This view differs only slightly from the simulator. In contrast to the simulator, you cannot write data: Only values are displayed.

Frequently asked questions

I own a CP343-1 Lean, can I use the software with it?2020-07-21T15:35:10+02:00

Yes, but please regard that the CP 343-1 Lean can only provide 4 connections. Our backup software needs 2 connections. Alternatively you may also use a Profinet-MPI adapter.

The number and structure of my building blocks change frequently, does this cause problems?2020-07-21T15:35:25+02:00

No. We have an automatic scan function for this case. This reads the structure and number of blocks from the PLC before a backup and automatically configures the following backup correctly.

Alternatively, you can define yourself which blocks should be backed up and which not, then the scan is switched off.

Why should the backup be done via PLC trigger?2020-07-21T15:36:07+02:00

In many cases a backup should only be performed in certain machine states, e.g. when the machine is in home position. This ensures that all backed up data is consistent with each other and that the machine is immediately ready for use in case of a recovery.

In simple environments where there are clearly defined machine downtimes, the backup can also be time-controlled. This can be at night, for example, when production is at a standstill. However, there are more and more machines and plants that do not have longer downtimes. For these machines a PLC-controlled data backup is very important. This is the only way to ensure that the backup is stored consistently.

I have password protected blocks. Can I also secure them?2020-07-21T15:36:08+02:00

The following applies to data blocks (DB): Yes

For all other modules, the following applies: We are currently working on this function. The next release will contain this function.

Can I backup my hardware configuration?2020-07-21T15:36:12+02:00

We are currently working on this function. The next release will include this function.

Which modules can I save?2020-07-21T15:36:24+02:00

For S7-300 and S7-400 applies:

– Data blocks and flags can be backed up with the DataBackup
– The saving of OBs, FCs and FBs is only possible with the DataBackupPro

For S7-1200, 1500 and ET200 applies:

– Non-optimized data blocks and flags can be saved with the DataBackup

How many controllers can I backup with the software?2020-07-21T15:36:32+02:00

In our software itself there is no limitation. Of course there are limits due to CPU power and network speeds. We cannot give an exact number, as this depends on your local conditions. A clue: We know customers who use our DataBackup software for more than 60 controllers without any problems.

Can I sell the software to my customers with my own logo?2020-07-21T15:39:35+02:00

You can provide our software with your own logo. Together with an adapted Excel template, this will result in a coherent overall picture.

An instrution for the so-called white labeling can be found in our user manual and is done very easily.

Is it possible to run the software without user login?2020-07-21T15:39:45+02:00

Yes, the software can be started as a Windows service. For details please refer to the manual.

I want to save many different S7 variables in Excel. Does it cost extra?2020-07-21T15:40:16+02:00

No. The number of variables is not limited by our software. Even the smallest license, the PLCDataReaderLite, can process any number of different variables.

How can I integrate formulas and graphics?2020-07-21T15:40:29+02:00

You can create and save an Excel file with the desired graphics, formulas and formatting using Excel. Then specify this file as a template in the trigger configuration in the program.

I need an official offer. How can I get one?2020-07-21T13:46:19+02:00
I have questions and need help. Does it cost me anything?2020-07-21T13:49:04+02:00

No, you can reach our support hotline from monday to friday between 8:30 am and 4:30 pm by phone and e-mail. All questions concerning the software, its functions and operation are answered by our own employees. We will be happy to help you further.

If you need extensive support with project planning and commissioning, you can take advantage of our extended service, which is subject to a charge.

I would like to install the software on a PC without internet connection, is that possible?2020-07-21T14:16:52+02:00

Yes, without any difficulties.

I’m a reseller. Do I get special conditions?2020-07-21T13:45:20+02:00

We do not offer special prices for resellers. Our prices are the same for all customers.

I want to generate the CSV/Excel file in a certain format, how can I do that?2020-07-21T15:41:28+02:00

You can define in the program where which data is written. You can also define a template file to display the data in your desired format.

I want to save a lot of PLC data in Excel files in a short time. How fast does this work?2020-07-21T15:41:52+02:00

This depends mainly on your setup. Which PLC do you use? Which PC? Where is the data stored?

If you are not sure whether the speed is sufficient, we recommend to make some tests in advance with our free trial version. With our free PLC scanner you can also test the speed of your setup and make changes if necessary.

Which file formats are supported?2020-07-21T15:41:44+02:00

Real Excel files (xlsx/xlsm) and CSV files are supported. For CSV files you can choose the separator and the date format freely.

I want to equip many machines with the Excel-PLC software. Which possibilities do I have?2020-07-21T15:45:19+02:00

For this case we offer a company license. This allows you to equip as many machines or plants as you like with our software. You only pay the one-time price, no matter how many installations you make.

Do I have to pay once more for updates?2020-07-21T15:24:50+02:00

No, if you have purchased a license, then you can download all updates up to the next major version free of charge from our download portal. Example: You have purchased version 1.1. An update with improvements and new functions appears as version 1.2. Now you can download and install the new version free of charge with your access data.

For a new main version, in this example version 2.0, you will receive an upgrade offer at special conditions as an existing customer.

Can I use a single user license on several PCs at the same time?2020-07-21T13:57:43+02:00

No. The single user licenses are intended for one PC. Simultaneous use on several PCs is not possible.

Can I transfer a single-user license, once installed, to another PC?2020-07-21T15:24:16+02:00

Yes, but only nine times. It is NOT a floating license. The transfer to another PC is only intended for the case of a hardware defect.

Can I resell my license?2020-07-21T15:24:34+02:00

Yes, that is expressly permitted.

Is it allowed to resell company license installations?2020-07-21T15:44:59+02:00

Yes, that is expressly permitted. Machine manufacturers or system integrators like to use our company license as a kind of license flat rate: pay once, create and sell as many installations as you like.

It should be noted in this context that we only provide support to the company license holder.
