IO-Link Diagnosis Tool (Protocol Analyzer)

The Diagnosis tool is an IO-Link analyzer that examines the IO-Link signal both electrically and logically. The acquired data is transmitted via USB to a supplied Diagnosis Tool PC software and evaluated. The IO-Link communication can be analyzed on byte-level, on M-sequence level, on protocol level and even on application level. The IO-Link communication is in the latter case visible in clear text. Folding, filtering and search functions simplify issue identification.

IO-Link Master/Device Tester

Every manufacturer of an IO-Link compliant device needs to issue a manufacturer declaration of compliance. This requires that numerous tests that are defined in the IO-Link test specification need to be executed. This device tester simplifies the execution of many of these tests in particular protocol compliance tests.

IO-Link Physical Layer Tester

TEConcept has developed a Physical Layer Tester “PLT” for Devices for execution of the Physical Layer Tests according to the IO-Link Test Specification（Latest Version V1.1.2）. The Physical Layer Tester is powered by an external 48V power supply, it is controlled via an USB port and it offers a standard M12 connector to connect the Devices under test "DUT". A PC-software tool asks for the IODD of the DUT and automatically adjusts most of its test procedures parameters according to the capabilities of the DUT. The test cases are defined by an XML-files that are accessible by the user.

EMC Test Master/Device

The IO-Link specification defines well defined procedures to test the EMC robustness of IO-Link devices. Some tests are checking the sensitivity of the IO-Link communication of IO-Link devices under EMC condit ions. This requires an robust master that is much less sensitive to EMC noise than the device under test.

USB based IO-Link Master

The 1-Port USB Master and 4-Port USB Master are ideally suited for engineering purposes and small PC-based applications. It uses the STMicroelectronics L6360 transceiver chip. A Windows based graphical user interface is included that reads IO-Link device descriptor files and offers an easy way to connect to all kinds of IO-Link devices.
