Use our guide to choose the right controller for your application.

Where do you want to install your controller? Find the right solution for every installation environment.

The controller is installed centrally in the control cabinet. Ideal for traditional machine designs with protected environments and centralized wiring.

The controller is installed in a decentralized manner but still within the control cabinet. It is suitable for compact machine designs with limited space and a modular design.

The controller is installed outside the traditional control cabinet, close to the machine. Ideal for robust, decentralized automation concepts directly in the field.

What kind of performance does your application require?

For simple to mid-range automation tasks (up to approximately 200 central I/Os) that require a compact design, integrated functionality, and cost-effective engineering.

For demanding applications involving large-scale structures, complex processes, or advanced technological requirements.

What programming languages should it support?

Support for core programming languages in TIA Portal. Suitable for classic automation tasks using Function Block Diagram (FBD), Ladder Diagram (LAD), or Structured Control Language (SCL).

In addition to FBD, LAD, and SCL, STL and GRAPH are also supported. Suitable for applications with sequential processes or existing STL code.

Additional support for high-level languages to implement complex automation tasks and specialized algorithms in industrial applications.

What motion control functions do you need?

For basic motion functions such as speed control, positioning, cam functions, measuring probes, and gear synchronization. Ideal for standard motion tasks in typical machines and classic automation systems.

For extended motion applications, including camming or simple kinematics with up to 4 axes of motion. Suitable for machines requiring more complex motion sequences.

For demanding motion control tasks involving cross-CPU synchronization or advanced kinematics with up to 6 motion axes. Ideal for highly dynamic machines and complex, precision-driven motion applications.

Do you want to use hardware-based or software-based control?

Classic automation using a dedicated hardware PLC. The control system runs on specially developed controller hardware and offers high reliability, performance, and industrial robustness.

The control functions are integrated directly into the drive. Suitable for compact machine designs that require minimal hardware and tight integration of motion and control functions.

The control system runs as software on an industrial PC. It is suitable for flexible automation concepts that require high computing performance and the integration of IT and automation functions.
