2. Introduction

WS433-CL is a wireless co-ordinator in a wireless sensor network, a high-performance type. It is able to configure the parameters for all end nodes in the network. By the Sub-Ghz technology from Texas Instruments, it is easy to establish multiple networks in same area without interference or channel conflict. One co-ordinator can handle maximum of 40 end nodes in its network. LOS transmission distance up to 6000m. The WS433-CL also has the option of adding an IoT Gateway built-in to facilitate remote configuration and diagnostics, as well as remote monitoring and control via any IIoT platform. The installation and configuration is very simple. Setting up a wireless sensor network has never been this easy.

5. Operation Principle

5.1 Add sensors node to Co-ordinator WS433-CL

5.1.1. Add Sensor Node ID automatically

Step 1: After supplying power the Co-ordinator via M12 connector, the Node ID must be registered within the first 5 minutes, up to 40 WS.

Step 2: Bring the wireless sensor closer to the Co-ordinator's antenna then take off the wireless sensor battery, wait for 5s then insert the battery again. If:

• Buzzer plays 1 peep sound, LED blink 1 time, that means registering Node ID on Co-ordinator successfully.
• Buzzer plays 2 peep sounds, LED blink 2 times, that this Node ID is already registered.

If you do not hear the "Peep" sound, please disconnect the power the co-ordinator, wait a few minute and try again.

Node id added in this way will be written to the smallest node_id_n address which is = 0.

Set Rssi_threshold (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL), default -25): The case if Co-ordinator is on high position and need to add node sensor. We set the sensor as close as possible and set the Rssi_threshold to -80, -90 or -100 to increase the sensitivity to allow WS433-CL-04 can add sensors at a longer distance. After that, perform 2 steps of adding sensors and then reset Rssi_threshold = -25.

Enb_auto_add_sensors configuration (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL)): In case you do not want to turn off the power WS433-CL, you can set Enb_auto_add_sensors = 1, this way we have 5 minutes to add nodes (add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0.

Memmap resgisters

You can download Modbus Memmap of WS433-CL with the following link:

5.1.2 Add sensor node into WS433-CL-04 (1) through intermediate WS433-CL-04 (2) and Modbus

IN CASE the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the sensor cannot be brought close to WS433-CL-04 (1).

First, you need to prepare

For example: WS433-CL-04 (1) has connected 1 sensor node and needs to connect 1 more sensor node WS433-M12F. So we use a WS433-CL-04 (2) to configure the 2nd sensor connected to WS433-CL-04 (1)

Step 1: Add Sensor Node ID automatically to WS433-CL-04 (2) (steps as above video) 

Step 2: Use the RS485 configuration cable to communicate with the Co-ordinator WS433-CL-04 (2) via Modbus software (in the link below), then write the ID of the Co-ordinator WS433-CL-04 (1) into "Co-ordinator id" and sync with the sensor node

How to use the Modbus configuration software 

 

• Unzip file and run file application Daviteq Modbus Configuration Tool Version

• Choose COM Port (the Port which is USB cable plugged in)
• Set the BaudRate: 9600, Parity: none
• Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the WS433-CL-04 is being connected with computer;
• Next, we need to import the configuration file for WS433-CL-04 by importing the csv file: Go to MENU: FILE / Import New / => select the file with name WS433-CL-Template Adding Wireless Sensor.csv (after unzip file).

• We can see that WS433-CL-04 (2) has connected the sensor to the sensor's id node s/n and the co-ordinator id s/n syncs with the sensor

• In the row Co-ordinator id sync to node 1, we change the co-ordinator id WS433-CL-04 (2) of sensor node to co-ordinator id WS433-CL-04 (1) by Uncheck Func 3 => change Func from 3 to 16

• Type in Setting Value the co-ordinator id of WS433-CL-04 (1) => Check Func 16 if Read Value show OK which mean it's wrote successful

• Change Func 16 to 3 then Check to read the value we just wrote in => if Read Value show the co-ordinator id of WS433-CL-04 (1) that mean the sensor node has sync with WS433-CL-04 (1)

Step 3: Using iConnector, Modbus on Globiots communicating with WS433-CL (1) to write node ID of sensor node to node address id = 0 followed by node id already in “Adding Wireless sensor (in the Modbus Memmap of WS433-CL)” area.

Ex: In globiots, create a parameter with the address space x3000 then create a modbus command according to the memmap file.

• Function 3: Read holding registers
• Function 4: Read input registers
• Function 16: Preset Multiple registers

• Next add container on the dashboard, then add the parameters created to container as button "Write ID Node 2"

• Click "Write ID Node 2" to write the id of node 2 to the co-ordinator WS433-CL-04

5.2 Configuring the co-ordinator WS433-CL

• Num of Node will indicate the number of nodes managed by WS433-CL.
• Every time a node is added, the Num of Node will increase by 1.
• Every time a node is deleted, the Num of Node is reduced by 1.
• Writing Num of Node = 0 will delete all 40 node ids to 0.
• If you want to delete a node id, then write it = 0 with the Write function is 16 and the Read function is 3.

First, you need to prepare

Step 1: Connect Antenna, RS485 - configuration cable and power supply co-ordinator

Step 2: Open Modbus tool on PC

• You can download Daviteq Modbus Configuration Tool with the following link:

5.6 Synchronizing configuration between WS433-CL and node:

For each node, there is a configuration synchronous zone from WS433-CL, consisting of 40 registers (80 bytes), see the start address for each node at "ADVANCED CONFIG (in the Modbus Memmap of WS433-CL)".

# of register	Description	Value Range	Default	Format	Explanation
1	Cycle_wakeup	1-3600(s)	120	uint16	Every time interval of Cycle_wakeup, sensor node would ONLY send data to co-ordinator if the new measured value was changed more than the Delta value of the last measured value. Default Cycle_wakeup is 120 seconds
1	Cycle_healthsta	60-7200(s)	600	uint16	Every time interval of Cycle_healthsta, sensor node will absolutely send data to co-ordinator regardless any condition
2	Co-ordinator id		0	uint32	Configure the ID number of Co-ordinator that wireless sensor want to connect to the Co-ordinator when only adding the sensor manually
2	Radio frequency	433.05-434.79, 433 Mhz	433.92	float	Configure the operating frequency of wireless sensor by Co-ordinator, should be configured from 433.05-434.79 MHz, only for advanced users
1	Tx power	-10,10,15	15	int16	Configure the RF power of wireless sensor by Co-ordinator, only for advanced users + 15 <=> tx power = 15dBm + 10 <=> tx power = 10dBm + -10 <=> tx power = -10dBm
1	Data rate RF	0-1	0	uint16	Configure the air data rate of wireless sensor by Co-ordinator, only for advanced users + 0 <=> data rate RF at 50kbps + 1 <=> data rate RF at 625bps

14	spare				Each type of WS node will have different configurations

When the WS433-CL power is turned on, the node's configuration will be read from flash, sync status = 99.

When the battery is plugged in or the power is turned on, the node sends the registration packet to the WS433-CL which contains the node's configuration. Configuration from the node will be overwritten on the configuration area on WS433-CL => Save flash => Sync completed, sync status = 0.

When users want to change the configuration on the node, use modbus RTU command 16 write to the configuration area on WS433-CL ==> sync status = 1: WS433-CL wait for the node to send data. When the node sends data, WS433-CL will send configuration to node, node sends back authentication ACK containing this new configuration ==> sync status = 0: sync configuration OK, users should read this new configuration section right.

Read the Sync status of 40 nodes in the "STATUS DATA OF 40 WIRELESS SENSORS (in the Modbus Memmap of WS433-CL)" area.

Sync status
0	sync ok
1	waiting for sync
99	power-on-reset default

5.7 Configuration of RF operation parameters

• Frequency 433.05 - 434.79Mhz, default 433.92Mhz
• RF transmit power: 10 dBm, 15dBm (default)
• Data rate of RF: 50kbps (default), 625bps

=> When changing the configuration of RF parameters, it must be reset for the WS433 board to operate under the new RF configuration. However, if you use the push button or the Magnetic sensor to change the RF data rate, there is no need to reset the board

5.7.1 The procedure for changing the frequency for the sensor and Co-or is as follows:

• Step 1: Use the Modbus Tool to change the frequency recording of each sensor, then remove the sensor battery, wait 10 seconds and reinsert it, then wait for 30 seconds, it will receive the configuration from Co-o, then confirm that the frequency change is successful. How to check on Co-or by Modbus Tool software.
• Step 2: Remove that sensor battery and set it aside;
• Step 3: Continue to step 1 for the next sensor;
• Step 4: After changing the frequency for all sensors, finally change the frequency for Co-or by using the Modbus Tool to write down, then turn off the power of co-or for 10 seconds and then power again, it will run at the new frequency, and connect to the sensor at the new frequency;

5.7.2 Change data rate: See more at section "5.3 Hall sensor and button function"

5.8 Modbus communication

Configuration:

• Protocol: Modbus RTU
• Address: 1 - 247
• Baud rate: 9600 , 19200
• Parity: none, even, odd
• Stop bits: 1

6. Installation

6.1 Mounting bracket installation

The mounting bracket is made from hard metallic material. Following to these steps as the below picture

Insert the top plastic housing and locking by L hex key

(NOTE: When reinstalling the cover, pay attention to put the PCB edge into the middle slot of the box inside as shown below)

6.2 Installation location

To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the two modules. In real life, there is no LOS condition. However, the two modules still communicate each other, but the distance will be reduced significantly.

Therefore, to maximize the transmission distance, please pay attention to the following conditions:

• DO NOT install the wireless module inside a complete metallic box or housing. The signal can not pass through metallic wall;
• This wireless module would be installed a semi-metallic box, because the RF signal can pass through the non-metal wall/are;
• The best case is to install the wireless module inside or Non-metallic box;

Some non-metallic materials: plastic, glass, wood, leather, concrete, cement…

6.3 IO Wiring & Sensor installation

7. Troubleshooting

No.	Phenomena	Reason	Solutions
1	Cannot read modbus	No power supply for WS433-CL, the power cord is incorrectly connected Modbus connection pin A, B is loose or wrong Configuration slave address, baudrate, parity is not correct Reading the wrong command, wrong address register	Check the power connection Check the connection modbus A, B Check the configuration of slave address, baudrate, parity WS433-CL only supports modbus 3, 4, and 16. Check if the value of modbus status returned by 2 or 3 is an incorrect address reading.
2	Failed to add auto sensor	When the first 5 minutes are up, the sensor cannot be added Node needs to be added further away from WS433-CL The WS433-CL and the node are configured to run at 2 different RF frequencies, or different data rates	Unplug, wait 10 seconds, plug in again to enable automatic add or write to modbus Enb_auto_add_sensors = 1 Bringing nodes and WS433-CL together or temporarily setting the smaller Rssi_threshold can add sensors farther (then return the old values) Check the RF frequency, data rate of WS433-CL and the node
3	Read modbus normal health values but read the data of the node, all are 0	The modbus 4 command only supports FW 1.9, old FWs can't read command 4	Check the FW of WS433-CL if it is older than 1.9 then use command 3 to read data and other registers
4	The node's data has no data of prm1 and prm2	The sensor attached to the node is loose For the WS433-M12F node, if the sensor is attached after the battery is attached to the node, the sensor type may be different so the data cannot be read.	Attach the sensor to the node firmly Attach the sensor to the WS433-M12F node first. Then remove the node pin, wait for 10 seconds, re-attach to the node to re-identify the sensor
