The following offers a range of application descriptions with their respective switching programs.
There are different types of samples. Some are made as introduction for new features especially for LOGO! 8 and LOGO! 7 (Getting Started), others are tips or partly applications which could be helpfully used within your own applications. LOGO! sets are complete applications with detailed descriptions which can directly be modified into your application.
You can simply download the switching programs, adapt them to your application by using the LOGO! Soft Comfort software and transfer them directly to LOGO! via a PC or Ethernet cable.
You will find two folders inside the download. This is because of changes in the LOGO! SoftComfort V8 screen in some positions (Messages, reference of parameters and so on), one for the former version and one for "LOGO!8 visualisation".
Hint: You can download the LOGO! Soft Comfort demo version free of charge and open the program file with the demo software.
If you have the demo version of LOGO! Soft Comfort, then you have the chance to develop a program for LOGO! and test it in the simulation mode.
Only restriction: you cannot transfer your programs to the a LOGO! hardware. You can save the program and transfer it later with a full version of the software.
Getting Started Here you find basic hints how to use new functions. The documents are a step by step instruction.
Tips & Tricks
Here you will find some hints as small program parts that can easily be implemented in your application.
Here you find small parts of programs that have to be completed and combined with other parts to become a full application.
Zip-files of getting started, Tips&Tricks and application parts can be downloaded directly. They include the original program files which can be modified with LOGO! Soft Comfort. Additionally they content a pdf file for those who don’t have a LOGO! Soft Comfort installed on the PC.
This are complete application samples with detailed documentation. They can easily be modified to your application.
As the LOGO! Sets have a more detailed documentation which also includes the projects of HMI panels or other communication partners, the table gives you the right link to the pages of the online support from where you can download the full project files. For the LOGO! Sets you need basic knowledge of LOGO! Soft Comfort.
The table shows to which LOGO! generation the program can be downloaded. The samples have been developed with LOGO! Soft Comfort with V4 or higher.
