101 )).
It has the following sub-structures:
Structure Contents
processdatamaster

Diagnostic data (temperature, voltage, current)

Status of the current / voltage supply
deviceinfo Device identification
timer[1] Subscribe to data
timer[2] Subscribe to data
iotsetup Parameters of the IoT port (access rights, IP settings, IP settings of the
LR SMARTOBSERVER)
fieldbussetup Parameters of the fieldbus port (IP settings, device identification in fieldbus
projection software)
iolinkmaster/port[n]


validation and data storage)

Digital input data (clamp 2)

Port event
iolinkmaster/port[n]/iolinkdevice



Reboot the device
The user can request the available data points and services in the substructures with
gettree (
→ Service: gettree
(
→ p.
102 )). The service returns the device description as tree structure. It
shows the services supported by a data point: In the sub-element "subs" each data point lists all
services that can be applied to it.
