IO-Link Device Connection
Every IO-Link device has its own connection to the controller. When an IO-Link device is
attached to a non-Fallback channel, the following data is provided through the
connection:
- Input tag – Process data input with timestamp, fault and status reporting, configuration change detection, and latest IO-Link event from the device
- Output tag – Process data output and reset configuration change
To set the RPI of the connection, see Connection View.
Connection Types
IO-Link devices may support multiple sets of process data. Each set of process data
is mapped to a connection type. Input and output tags for each connection type is
generated from their respective set of process data that is defined in the device
IODD.
To determine the type of process data that the device provides, select the type of
connection in the Module Definition dialog. For more information, see Module Definition.
