Which safety functions can you use with the interpolation on the fail-safe Technology CPU?

  • Entry
  • Associated product(s)

The fail-safe Technology CPU 317TF-2 DP unites three CPU functions in one device:

  1. Standard SIMATIC PLC
  2. Fail-safe PLC (with Distributed Safety)
  3. Motion Control

As from version V4.2 of S7 Technology (and the associated CPU firmware) it is also possible to perform interpolated travel with the Technology CPU.
The special points about using interpolated travel with the
Technology CPU in conjunction with the integrated safety functions of
Safety Integrated are explained in the attached PDF file.

The safety functions explained in the attached PDF file apply analogously to synchronized axes. In the case of activated safety functions the synchronized axes must be controlled via master axis. The path object technology functions named in the attached PDF file could not be used in combination with synchronized axes.
