SafePLC® MEETS DRIVE - Safety advanced®

With its integral technology functions, the SMX series ensures that a safety task can be implemented quickly and easily. An extensive library of functions is available for pre-processing sensors (inputs) or actuators (outputs), above all for safe drive monitoring. Simple linking of input, monitoring and output functions using logic blocks means that even extensive safety functions can be established very quickly and transparently.

All the functions are open in terms of the sensors, drives and actuators used. Independent of the drive technology used, whether that means an electric drive with a vector or frequency controller, pneumatic or hydraulic drives, the SMX series delivers the ideal solution for complete safety management in mechanical and plant engineering.

Convenient programming

The new SafePLC² programming interface meets the needs of a modern programming interface and for the first time combines all the series of our safety controllers with each other. The view of the programming interface can be customised to suit the needs of every user. A very extensive library with sensors and actors is already available to users. These can be adjusted and extended to suit the needs of the customer.

Module management / device assignment

The various modules (inputs/outputs and axis monitors) are assigned to the senses and functions of the machine/ system on the basis of the required performance level. For example, for a three-dimensional movement of three connected drive axes, and axis module is required for x, y and z. It is of no consequence for safety monitoring whether electric, pneumatic or hydraulic drives are used.

Network diagram

If network-based safety controls are used, the relevant network cards are displayed and diagnosed.

Wiring diagram

A wiring diagram is automatically generated by the configuration of the safety controllers and the sensors and actors. This can be exported to EPLAN.

Function diagram

Function diagram-based programming with logic elements. The monitoring functions can be linked to each other by logical operators. The speeds, accelerations and positions of multiple axes are monitored relative to each other. The monitoring tasks which are implemented can be distributed and documented very clearly using various pages.

Command units, sensors and controller architecture

All conventional command devices and sensors used in safety applications such as buttons, Emergency Stops, door contacts, two-hand buttons, light curtains, mode selection switches and limit switches our available using icons in the form of preconfigured elements. When included in the terminal scheme, these elements are assigned to the module to which it is physically connected.

Axis-/Sensor configuration


One or two sensors are required depending on the safety category to enable safe speed and/or position identification of the various axes in the system. A separate menu with wide-ranging entry and calculation help is provided for the configuration of the sensor type and the technical data as well as for the axis-related resolution. This makes it possible to find the correct input data without requiring any special prior knowledge.

Monitoring function

Powerful functions for motion monitoring such as speed, standstill, zone and direction monitors as well as Emergency Stop, destination travel and step size monitoring are available for selection. The functions can be parameterised immediately on a context basis after they have been selected.

Group function

Tested function modules can be taken from a library or bespoke function modules can be defined, protected and saved for reuse.
