Checksums
Using the checksums, it can be identified as to whether the configuration and/or
parameterization of Safety Integrated was changed.
An acceptance test is required after changing the checksums. The system outputs the
appropriate messages to indicate that an acceptance test is required. The checksums are
used for documentation purposes within the scope of an acceptance test.
The parameterization can be transferred to several devices by separating the checksums for
function and communication. When transferring the parameterization to several devices, you
must check whether the device is correctly assigned in the communication group.
More information
Further information about the checksums is provided in the parameter list.

Overview
The machine manufacturer is responsible in ensuring that the plant or machine functions
perfectly. As a consequence, after commissioning, the machine manufacturer must check those
functions which represent an increased risk of injury or material damage, or have them checked
by specialist personnel. This acceptance or validation is specified in the European Machinery
Directive and comprises 2 parts:
• Acceptance test: Check the safety-relevant functions and machine parts after
commissioning.
• Documentation: Generate an "Acceptance report" that describes the test results.
ISO 13849‑1 provides additional information relating to validation, for example. The
acceptance test requirements (configuration check) for the safety functions of electric drives
are based on IEC 61800-5-2.
