13FFh: Safety Configuration Signature (checksum)
This object 13FFh contains the signatures (checksums) via the CANopen Safety parameters of
the SRDO1 configuration. Only a checksum which is valid at that time can be transmitted. The
checksum is checked anew before switching the configuration to valid. Any change to the
configuration will be valid only after passing.
