The IO_Link_Port_Data UDT consists of the 48 input bytes (SINTs) and 48 output bytes (SINTs) that
the IO-Link master allocates to each port. Under normal operating conditions, the user will not be
aware of any data being passed through this UDT. The AOI automates the parsing of the data for each
port and allows the user to access the data directly without mapping each of the four port’s data into the
master’s single data buffer. This UDT is used for both the IO-Link master AOI as well as each IO-Link
slave AOI. The master and slave must share the same tag name for the corresponding port.

Inputs – this 48-byte SINT array contains all raw input data values being passed from the IO-
Link slave device input array to the master device input array.

Outputs – this 48-byte SINT array contain all raw output data values being passed from the IO-
Link slave device output array to the master device output array.
