In addition to the specification development of IO-Link Safety, technology provider companies have implemented test systems for FS masters and FS devices, thus ensuring a high level of maturity of the test specification V1.1.
A new FS master test system consisting of the test program on a Windows PC and a controllable and readable test hardware acting as a pseudo FS device can now test all FS master functions according to the test specification, including OSSDe operation. This test system also plays a major role in integration tests in safe fieldbus systems (e.g. PROFIsafe). The well-known “USB master”, which already supports the testing of normal devices, can also parameterize and test IO-Link Safety FS devices in an expansion stage.
Discussions are currently underway with test centers on how these test systems can be integrated into the safety certification of the devices. The safety certification itself has already been agreed and defined in the test specification.
Companies gained initial experience with the tests at the first workshop for IO-Link Safety FS-Master and FS-Devices in November last year. At that time, seven companies with five FS master and six FS device implementations tested the mutual operation and test programs. This experience has already been incorporated into version 1.1 of the test specification.
Due to the great success, three more workshops are now planned in 2022. The next one will take place on April 07 in Karlsruhe-Durlach; the others on June 30 and October 20.
Interested companies who would like to participate with their products/prototypes are asked to register for a date early via the office (info(at)io-link(dot)com).
