- STG-700.

What is miCon-L?

miCon-L is the graphical programming software for BARTH mini PLCs of the STG series. In miCon-L, function blocks, which include technical signs and symbols, are connected so they become a network.


In miCon-L function blocks are connected data-flow oriented, so a block diagram is designed. The application is downloaded on the mini PLC and is then being translated into machine-readable code.

The logic processing and the high recognizability of function bocks make starting-off with miCon-L really easy. No programming language has to be learned. The design of the function blocks is according to existing graphical specification and technical languages.

Structure blocks allow a hierarchical structure of the projects. By adding and exporting projects, existing structure blocks can easily be reused.

Simulation, Test and Run mode

In simulation mode, the application can be checked for errors while programming and without connecting an STG to the PC.

After the network of structure and function blocks is designed, it can be downloaded on the mini PLC. The application can then be watched and checked for errors in real time. Special visualization blocks allow an insight to the transmitted signals and their values, which helps for the check-up.

From the video “First steps with miCon-L” you will get a general look into the graphical programming software miCon-L. Topics of the video include f. e. downloading the software, design of the user interface and the most important steps to start developing an application. The tutorial is part of a tutorial series with an example, from which you can learn how to use miCon-L.

You can find the whole tutorial series here.

Please find further information about installation and first steps in the section „Support“.

Examples and Projects

In the section Examples and Projects you can find comprehensive examples for beginners and experts. According to the examples you can see how easy it is to write an application with miCon-L yourself.

The introduced projects will show you what is possible with miCon-L and the BARTH mini PLCs.

Here you can see two of the examples:

Connect Graf-Systeco’s display D1000 over CAN bus

In this example we will show you, how you can connect the mini PLC STG-650 and STG-550 with a graphic display of the company Graf-Syteco over CAN bus. Graf-Syteco’s displays are mainly used in construction machinery, agricultural machinery, commercial vehicles and the navy, so they are the ideal addition to the robust mini PLCs of the company Barth.

Experimental setup with STG-570, STG-700 and stepper motor

The idea is to use the STG-570 CAN to communicate with the STG-700 STEP via CAN bus. A stepper motor is controlled by a potentiometer.
