No. Phenomena Reason Solutions
1 Cannot read modbus
No power supply, 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
iConnector 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
(iConnector integrated Co-
ordinator version)
When the first 5
minutes are up, the
sensor cannot be added
Node needs to be
added further away
from WS433-CL
The iConnector 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 iConnector
together or temporarily setting
the smaller Rssi_threshold can
add sensors farther (then return
the old values)
Check the RF frequency, data rate
of iConnector 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 in
iConnector 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
5
Status led of iConnector
doesn’t light
No power supply
Check if the power cable is
disconnected
Check if the connector of
iConnector is loose or
disconnected
6
Mobus led of iConnector
doesn’t light
No RS485 connection
Check if the signal cable is loose
or disconnected
7
Network led of iConnector
doesn’t light
No network connection
Check if the power cable is
disconnected
Check if the connector of
iConnector is loose or
disconnected
