Verification and validation 459
The validation test must include at least the following steps:
• preparing a validation test plan
• testing all commissioned functions for proper operation in the final complete
safety system
• testing all used inputs for proper operation, also for the input redundancy. See
also Validation of redundant inputs on page 464 .
• testing all used outputs for proper operation
• documenting all validation tests performed
• testing person signing and archiving the validation test report for further
reference.

Validation test reports
You must store the signed acceptance test reports in the logbook of the machine. The
report must include, as required by the referred standards:
• description of the safety application (including a figure)
• a description and revisions of safety components that are used in the safety
application
• a list of all safety functions that are used in the safety application
• a list of all safety related parameters and their values (the drive STO has no
safety-related parameters, but listing the non-safety related parameter
31.22
STO indication run/stop and its setting is recommended)
• documentation of start-up activities, references to failure reports and resolution
of failures
• the test results for each safety function, all safety parameter values including the
CRC value of the safety configuration (parameter
200.254 ), date of the tests and
confirmation by the test personnel.
You must store any new acceptance test reports performed due to changes or
maintenance in the logbook of the machine.

Competence
The validation test of the safety function must be carried out by a competent person
with expertise and knowledge of the safety function as well as functional safety, as
required by IEC 61508-1 clause 6. The test procedures and report must be
documented and signed by this person.

Tools
You need the Drive composer pro PC tool to perform the validation procedures.
