The following tables specify the Profiles available for IO-Link Devices and Masters that implement the OPC UA for IO-Link Information Model companion specification.
This Profile supports the information for IO-Link Masters and IO-Link Devices. It does not include support for IO-Link Device Description file handling.
This Profile is intended to be used of OPC UA servers with limited resources. It is built upon the “Micro Embedded Device 2017 Server Profile” Profile, which supports subscriptions and at least two sessions.
The content of the Profile if defined in Table 79.
