Every manufacturer of IO-Link Safety Masters needs to run tests specified in the current IO-Link Safety Test specification V1.1.3 successfully as precondition for the assessment of a named body (e.g., TÜV). Precondition for Safety tests are the Standard IO-Link Master Tests that are executed by a different tool.
IO-Link Test Specification describes tests of the Safety Communication Layer “SCL” based on test vectors that were automatically generated and approved by a named body (IFAK tests).
To run the Safety Tests, the Master Manufacturer must implement an Upper Tester (UT) and an SMI Test Communication Server.
The IFAK test vectors are submitted by the Safety Master Tester Unit to the Master Under Test. Some additional Test cases, such as the Splitter / Composer test are triggered via the STCS.
