Version: 2.0.0
Parameter data exchange
An intelligent IO-Link device can support parameterization through SPDUs (service protocol data units). The
PLC must explicitly query or, when marked as such, send these acyclic service data.
Note
SPDU access
TwinCAT currently only supports access via ADS.
The so-called SPDU index is used to address the corresponding parameter. The following ranges are
available.
Index range
Name
0x00...0x0F
System
0x10...0x1F
Identification
0x20...0x2F
Diagnostic
0x30...0x3F
Communication
0x40...0xFE
Preferred Index
0x0100...0x3FFF
Extended Index
0x4000...0xFFFF
not specified (reserved)
The use and implementation of these ranges is the responsibility of the sensor/actuator manufacturer.
For clarification, just a few of the possible indices are listed here; refer to the documentation for the IO-Link
device used.
