What is a CRC check?

CRC Check

Cyclic redundancy check:

This is a procedure for determining a check value for data to detect errors in transmission or saving.

To increase data integrity, data transfer between the data carrier and processor unit and the storage device must be monitored using a check procedure.

A CRC check can be enabled for this via parameter configuration.

With the CRC check, a check code that allows the validity to be checked at any time is written to the data carrier.


A CRC data check provides the following advantages:

  • Data integrity even during the non-active phase (data carrier outside the R/W head).
  • Shorter read time – page is read once.
