2.1 Overview

Product label
2.2 Description
The NETRIS®3 transmits data over long distances by means of innovative LPWAN®
technology (“Low-Power Wide-Area Network”). It is therefore possible to carry out
installations inside buildings, in cellars or in underground tanks without any problems.
The transmission of the measured values to the IIoT platform is carried out at a preset
sending interval.The measurement and sending intervals, and also the alarm limits,
for particular measured values can be configured over the LoRaWAN®protocol. A
configuration can be carried out via the cloud.
2.3 Functional principle
The measuring signal is transmitted digitally from the WIKA measuring instrument via a
cable to the NETRIS®3 and wirelessly via the antenna of the radio module to a gateway.
The NETRIS®3 uses the LoRaWAN®radio standard, class A, which is designed for
energy-saving operation.
This means that communication with a suitable gateway mainly consists of uplinks
(messages originating from the measuring instrument). An uplink always occurs in regular,
preset cycles (transmission rate).The measuring rate can be defined independently of the



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
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.
→ For details, see website: https://lora-alliance.org
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®gateway and the measured values are
transmitted to the IIoT infrastructure at freely configurable intervals. For instrument-specific
registration data for the LoRaWAN®network, see quick start guide (included in delivery).
2.5 LoRaWAN®specification
For the data transmission NETRIS®3 uses LoRaWAN®version 1.0.3.

3.2 Intended use
The model NETRIS®3 is a radio unit that transmits data of a sensor or measuring
instrument and is used for condition-oriented and preventive or corrective maintenance in
industrial applications.
The instrument can be used wherever centralised, web-based remote monitoring is
required in Ex-protected areas.
The remote monitoring of the process pressure via radio transmission is only suitable for
non-critical and non-safety-relevant applications.
The LoRaWAN®signal may only be used for mobile applications to a limited
extend.This applies particularly to high spreading factors.
The remote monitoring of the measuring location is achieved over a
web-based platform.
Only use the instrument in applications that lie within its technical performance limits.
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.The manufacturer shall not be liable for claims of any
type based on operation contrary to the intended use.
