LOGO!Soft Comfort V6.1

It is recommended to always keep the LOGO! Soft Comfort software up to date with the latest Upgrades/Updates. Updated software is required to be able to communicate with the latest device releases.

An Update improves the software within the same version e.g. from V6.0.17 to V6.1.12 via a Service Pack (SP). It is possible to update directly from Internet within LOGO! Soft Comfort or via downloading and installing the required files.

An Upgrade improves the software to a higher version, e.g. from V4 to V8.
This can be done via the internet directly within LOGO! Soft Comfort or downloading and installing the required files or purchasing the upgrade on a CD.
PREREQUISITE: A fully functional, original, licensed version of LOGO! Soft Comfort must already be installed.

Demo software

With a demo version of LOGO! Soft Comfort, you can easily familiarise yourself with the LOGO!. You can create, simulate, archive and print out circuit programs via a PC for all LOGO! devices.
RESTRICTION: You cannot transfer (download or upload) the circuit programs to/from a LOGO!.
It is therefore also not possible to perform on-line monitoring or tests of a running program.
These features are only possible with a full version of the software.
A program developed with the demosoftware can be further developed and transferred afterwards with the full version!
As ideal tool for the familiarisation is the WBT (first Steps with LOGO! 8).
