8.6.7 The IO-Link function block IOL_CALL
The IO-Link function block IOL_CALL is specified in the IO-Link specification "IO-Link Integration
Part 1- Technical Specification for PROFIBUS and PROFINET“".
Depending on the PLC manufacturer, the IO-Link CALL function block can differ from the spe-
cification (for example in the representation or the use of variables).
