B&R makes it easier to create safety applications with a series of new mapp functions in SafeDESIGNER. It is also possible to use a combination of data from the standard application to generate safety-relevant data.

B&R is expanding the existing table functions for safety technology by two: A lookup table allows easy conversions and a two-dimensional table can be used to implement array functions when programming.

  • Highlights
  • Safe data from functional signals up to PL d
  • Easily solve complex calculations
  • LookUp tables and array functions

Data to SafeDATA

The Data-to-SafeDATA function determines a safe speed and a safe position using data from the standard application. This is done by comparing speed and position data from two standard (non-safety) X20DC1196 I/O modules with each other. With the help of the functions provided, the data can be used as the safe speed for applications up to PL d and the safe position for applications up to PL c .

Another use case is safe evaluation of signals from strain gauges. If two X67AI2744 modules with one strain gauge sensor each are used, safe strain information can be created for applications up to PL d.

Advanced mathematics

With advanced mathematics functions, B&R makes it easier to make complex calculations in an application. All data is calculated as fixed point numbers. The user does not need to use the internal floating-point calculations and does not have to worry about rounding, resolution or buffer overflow errors.
