Access to the IoT core only via port<IOL_IoT_Core>.
General notes on the ifm IoT Core: → Programmers' notes (→ p. 45)
The AL1940 is of type device (→ Overview: IoT types (→ p. 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]
 Parameters of the IO-Link port (operating mode, transmission rate, cycle time,
validation and data storage)
 Digital input data (clamp 2)
 Port event
iolinkmaster/port[n]/iolinkdevice
 Status information IO-Link devices on the IO-Link port
 Device information of the IO-Link device
 Process data on input/output
 Application-specific identification
firmware
 Firmware of the device
 Reset devices
 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.
