2. Design and function

2.1 Overview

Cable gland Fixing holes

Internal antenna Status LED

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









2. Design and function

6WIKA operating instructions, model WIKA NETRIS®3

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.

3.3 Improper use

WARNING!

Changes to the instrument

Changes to the instrument can lead to hazardous situations and injuries.

▶Refrain from unauthorised modifications or changes to the instrument.

▶The instrument must only be used for the usage described here.

3. Safety

14521664.02 03/2023 EN/DE

WARNING!

Injuries through improper use

Improper use of the instrument can lead to hazardous situations and injuries.

▶Refrain from unauthorised modifications to the instrument.

The remote monitoring function must not be used for control purposes,

as it cannot be guaranteed that data packets won't be lost during radio

transmission.

Any use beyond or different to the intended use is considered as improper use.

3.4 Responsibility of the operator

The instrument is used in the industrial sector.The operator is therefore responsible for

legal obligations regarding safety at work.

The operator is obliged to maintain the product label in a legible condition.

To ensure safe working on the instrument, the operating company must ensure

■that suitable first-aid equipment is available and aid is provided whenever required.

■that the operating personnel are regularly instructed in all topics regarding safety at

work, first aid and environmental protection and know the operating instructions and in

particular, the safety instructions contained therein.

■that the instrument is suitable for the particular application in accordance with its

intended use.

■that personal protective equipment is available.

With increased requirements for technical cleanliness, suitability for the

application must be checked by the operator before commissioning.

3.5 Personnel qualification

WARNING!

Risk of injury should qualification be insufficient

Improper handling can result in considerable injury and damage to property.

▶The activities described in these operating instructions may only be carried

out by skilled personnel who have the qualifications described below.
