TrySim Lite – the students version of TrySim

What does TrySim Lite can?

TrySim is no learning program. From the beginning we did not created it like that. TrySim does not contain anything especially for learning, either.

Version V3.2 or V4.0?

The current version is V4.0 and we recommend it in the majority of cases. Only if you want to send projects to users of V3.2 this version should be used. Please mention it when ordering because then we have to send an old dongle.
Users of V3.2 can change to the new version by a simple download of V4.0.

TrySim Lite ist almost like the full version. The differences are:

  • It only costs € 35 (Quantity discount, see below)
  • It may only be used in private, not in firms, schools and other organisations.
  • The programs generated with TrySim lite can not be exported, this means they can only be used to control machines within TrySim. The import of programs that have been written on another PLC development system is not possible, either. Furthermore the interface to real controllers which is important for professional usage is nonexistent.


  • With TrySim Lite you can construct and control machines of any size.
  • You can write all types of building blocks (OB, FB, FC, DB) in STL, FBD or LAD.
  • Of course you can save and print the program.
  • You can consult us via email.

Since september 2008 we do no longer send CDs, but you have to download the software at (4,6 MB). You receive the licence key (USB dongle) by post.

In september 2008 we have converted the sales of the lite version to avoid compatibility problems. Every student who has bought the lite version can now download the current version from the internet. If the school also has the current version a data exchange is possible in both directions. But many schools do not have the current version because they did not buy an update for years. We regret problems resulting from that, but we can not show consideration for this any more in the interests of our professional customers.

Why not use the free demo version?

For just exercising PLC programming and to see small, self-constructed and self-controlled machines in action, the demo version is completely sufficient.
However, we do not guarantee that projects created with the demo version are compatible with any other version.
