Pluggable safety key

The safety key must be inserted when activating the MOVISAFE® CS..A safety option and must not be removed while the safety option is active.

The parameterization data of the MOVISAFE® CS..A safety option is divided into application data and the key data set. The key data set ensures data integrity.

The application data is stored in the device. The application data is enabled with the aid of the key data set on the pluggable safety key. The safety option becomes operational only if the key data set on the pluggable safety key matches the parameterization.

The pluggable safety key is also used to establish a location reference in the system. Since the application-related data set is enabled only with the matching key data set on the pluggable safety key, the location reference can be established in this way. It is the user's responsibility to save the location reference of the pluggable safety key in the system.

The data for safe communication as well as safe referencing is also stored on the pluggable safety key because this data has the same location reference.

This ensures that the application-related data and the communication data is available again immediately in the event of a device replacement.

If a system error occurs while saving referencing data, replace the safety key (see chapter Replacing the safety key).

WARNING

After switching the safety option off and on again, the error is no longer signaled.
Severe or fatal injuries.
  • Make sure that the position reference between the safety option and the application is correct.

The safety key contains the following data:

  • Checksum of the application data set
  • Checksum of the accepted data set
  • Checksum bus (ParCRCBus)
  • Parameter of the F-protocol
  • Referencing data
