5 IO-Link – functions for acyclic communication
5.1 General
The acyclic access to the data of IO-Link devices is realized via IO-Link CALLs.
Therefore it is necessary to distinguish between data of an IO-Link master or of an IO-Link device.
The addressing of the IO-Link CALL is realized via the so called Entity_Port- It defines which device
is addressed via the CALL:
Entity_Port 0 = IO-Link master module (IOLM)
Entitiy_Port 1 = IO-Link device at 1st IO-Link channel (IOL1)
Entitiy_Port 2 = IO-Link device at 2nd IO-Link channel (IOL2)
