IO-Link Master Tester - Reliably test and certify the Master protocol
The IO-Link Master Tester communicates via SMI services with the SMI Test Communication Server “STCS” to be provided by the Master manufacturer, which maps SMI services to a specific Master.
In IO-Link V1.1.3, a standardized master interface (SMI) was introduced, which specifies methods for communicating with an IO-Link Master in an abstract manner.
The IO-Link test specification for the Master test has been extensively revised.
The Master Tester has been completely redesigned. It is based on a Master Tester Application “MTA” that runs on Windows 7 and newer, and a Master Tester Unit “MTU”, as specified in the IO-Link test specification.
A prerequisite for creating a manufacturer’s declaration of conformance by the manufacturer of an IO-Link Master is the successful completion of the conformity tests specified in the current IO-Link test specification.

Additional test systems for your IO-Link Master project
In addition to the protocol test, the physical layer test and the EMC test are also required for complete IO-Link certification (Test & Quality IO-Link Community). To achieve this goal with as little effort as possible, TEConcept offers additional diagnostic & test tools that can be used directly by IO-Link Community members to issue the required certifications. For non-members, TEConcept, as an accredited IO-Link Competence and Test Center, carries out the certification tests.

IO-Link Safety Master Tester
Test system for the manufacturer's declaration of IO-Link Safety Masters — a mandatory requirement for safety assessment by notified bodies such as TÜV. Automatically transmits IFAK-approved test vectors and generates a PDF test report.

IO-Link EMC Test Device
Standard-compliant test device for the EMC conformity test of IO-Link Masters according to IO-Link Interface Specification Annex H.2.2. Counts parity, checksum, and timeout errors separately, supports all three COM rates, and enables round-trip delay measurements.
