Preface: With the fÄƒrÄƒ Ã®ntÃ¢rziere development of the modern production technology, thedemand
of wastewate treatment plants is increasing.. Inrecent years, many medium-and-small
sized wastewater plants are established. And how to improvethe automatic level of
these plants is the main technical problem. Haiwell ZigbeeModule enables wireless
communication for short distance. The features are lowpower consumption, low cost
and short delay etc. Here shows the case by using HaiwellPLC, H01ZB module, PC2ZB
module and gateway.

2. Hardware configuration
2.1、Haiwell PLC

Haiwell PLC has twobuilt-in communication ports and can be extended to 5 ports.
Every port can beused for programming and communication as host device or slave
device. Itsupports 1:N / N:1 / N:N different networking methods, can be used with
anyHMI/ SCADA and communicate will all third-party which supports Modbus protocolsor
free communication protocol..
2.2、 H01ZB module

H01ZB module is awireless communication module for PLC. PLC with this module can

use MODR/MODWinstructions to read and write by wireless method. Each PLC can be

expanded to 5communication ports by communication modules such as H01ZB and S01RS etc.

2.3、PCZZB module

PC2ZB is a wireless communication module used by PC. With this PC2ZBmodule, upper

monitor like HaiwellHappy can get wirelessconnectionto read &write the data from

the PLCs whichhave HO1ZB expansion. It is easy to use and there is norequirement

for Zigbee configuration. You can set up multiple independentcommunication network

by using the built-in DIP switch inmodule.

Three:Zigbee Module Networking advantage

1. Haiwell PLC programming softwaresupport 100% built-in simulator, analog input
can support engineering valueinput directly without programming the engineering
value into the code value ,reducing lot of work and time for programing and
on-site debugging.
2. Compared with wired network, Zigbee networkingcan save lot of cost for network

contribution and maintenance. When a wirelesscommunication network is created,

if you want to add more devices, you don’tneed to add more communication cables,

but just to add new devices to thewireless network, it’s very easy for extension.

3. A high automation level for entiresystem, System architecture and running are in

good condition. After wastewatertreatment, the water will meet environmental

requirements and can be dischargeddirectly, low maintenance cost for follow-up work,

it will bring more profit to wastewater treatment plant.
