NX/GX-series IO-Link System User's Manual (W570)
Data that an IO-Link device inputs to the IO-Link master.
It includes the following:
•
IO-Link process input data from communications, digital inputs from pin 2, and digital in-
puts from general-purpose (non-IO-Link) devices.
A flag that indicates whether the IO-Link process input data is enabled or disabled for each
port.
Output data from communications in IO-Link Mode (i.e., the data that is sent from the IO-
Link master to the IO-Link devices).
Input data from IO-Link communications in IO-Link Mode (i.e., the data that is sent from the
IO-Link devices to the IO-Link master).
An I/O connection port of the IO-Link master. In this manual, they are simply referred to as
"ports".
Because you can use ports for digital inputs and digital outputs in addition to IO-Link com-
munications, they are not called "IO-Link communications ports".
Communications that are performed only when requested. Message communications are
acyclic communications.
IO-Link event notifications are not included. Acyclic communications include message com-
munications and event notifications.
There are two types of message communications in an IO-Link System: message commu-
nications from the controller to the IO-Link master and message communications through
the IO-Link master to the IO-Link devices.
