2. Design and function
transmission rate. If an alarm limit is exceeded or dropped below during a measuring cycle,
a data transfer is carried out immediately, regardless of the set transmission rate.
After a successful uplink, two time-limited windows can be used for the downlink (message
EN
to the measuring instrument). This enables bidirectional communication and the receipt of
network control commands. If this possibility is not used, the end device can only receive
data after a new uplink.

Typical uplinks:
Measured values: depending on the particular measuring instrument
■
Process alarms: can be set accordingly
■
Technical alarm: reflects the status of the instrument as well as the quality and reliability
■
of the measurement.
The alarm of the radio unit: based on the overall condition of the system. If this alarm
■
occurs, the occurrence of a process alarm and also the cyclic measured values must be
looked into
Notifications for fault diagnosis
■
Configuration ID (for the identification of changes in the measuring and sending rate)
■
Typical downlink:
Configuration change (e.g. measuring rate, sending rate, alarm parameter etc.).
The WIKA radio unit automatically detects, in the case of messages to be confirmed (e.g.
alarms), that the transmission packet has not arrived and transmits it again with changed
transmission properties (spreading factors) until the receipt is confirmed by the system.
Higher spreading factors lead to an increased range, a longer sending time
and also an increased energy consumption of the radio device.

2.4 Connection to IIoT platform

The instrument is connected to a LoRaWAN
transmitted to the IIoT infrastructure at freely configurable intervals. For instrument-specific
