9.2.9 Read diagnostic data of the AL1950
52253
The AL1950 provides diagnostic data.
Substructure: processdatamaster
Available data points:
Name Description Access
../temperature Temperature of the IO-Link master (value in °C) r
../voltage Voltage applied (value in V) r
../current Current (value in A) r
../supervisionstatus Diagnostic information of the device supply r
r ... read only
>
Example: Read several parameter values of the IO-Link master simultaneously
33840
Task: The following current values are to be read by the IO-Link master: temperature, serial number
Solution: Read the current parameter values using the getdatamulti service (data point temperature:
/processdatamaster/temperature; data point serial number: /deviceinfo/serialnumber)
