Notice

Measuring errors due to EMC

The digital inputs are optimized for fast signal transmission and are therefore susceptible to electromagnetic interference.

Under the influence of electromagnetic interference, incorrect signal levels or edges can be detected.

  • If necessary, use shielded signal lines or enable the digital filters, see chapter Filter.
