IO-Link Configurable Observable Device – Device emulation for developing IO-Link Masters and IO-Link Devices

When developing IO-Link Masters, there is often a strong need to test various edge cases. For example, how the IO-Link Master behaves with the largest data storage sizes, or how it reacts when the IO-Link Device does not respond or responds with a delay. The IO-Link Configurable Observable Device (COD) offers a wide range of options to extend regular protocol tests with customer-specific tests for IO-Link Masters. Furthermore, the COD can emulate any IO-Link Device based on its IODD.

The COD is an IO-Link Device that can be configured and parameterized via REST API. The actual hardware communicates with the PC via USB. The REST API is provided by a PC-side server application called the COD Communication Server.

Can I test the IO-Link COD before buying?

Yes – we rent out the COD for 3 or 6 months. If you then decide to buy it, the rental fee is credited in full.
