Our function blocks are grouped by theme. For example, we offer block libraries for PC Worx, PC WORX EXPRESS or Step7 that are optimally tailored to the relevant software. For I/O terminals, you'll find blocks for easy access to analog or digital signals, for parameterization or monitoring.

Blocks for function terminals contain control functions and communication options. Technology blocks offer functions such as database access, network monitoring or ready-made applications for embedding the controller in its surroundings.

In addition, we offer sector-specific block libraries, e.g., for controlling wind power plants, outfitting ships, conveyor technology or machine engineering.

The vast majority of our function blocks can be used free of charge. Choose which function you want to integrate in your control system and download the corresponding function block from our homepage. You can then use the block for as long as you wish.

In particular, blocks with technology functions or for supporting specific protocols require runtime licenses in order to be used on controllers.

Runtime licenses are stored on memory cards, which are available as accessories for the controllers. If a block requires a license, the control program checks whether a license is present. If it is, the block can be used without any restrictions. If no license is present, the function blocks will work for six hours and will then be disabled.

You can also use our wide range of function blocks for programming with PC WORX EXPRESS. The software development environment supports libraries that are created with PC Worx Version 6.0 or later. If a library is only available in an older version, it can be transferred using the PC WORX DEMO software and also used in PC WORX EXPRESS.
