THERMASGARD-36600-2025-Temperature-Measuring-
Transducer-1

W-Modbus sensor (slave)

STATUS LEDS
The two LEDs L1 and L2 (on the right of the “Pair” push-button) indicate the wireless state of the sensor. They activate after the system is switched on and deactivate automatically after approx. 30 minutes.
If required, the LEDs can be reactivated manually using the “Pair” push- button.

TELEGRAM LED
The LED (on the left of DIP switch A) flashes to indicate that Modbus communication is active.
If there is a fault in the Modbus cables, the LED lights up red steadily.

“PAIR” PUSH-BUTTON

Different functions are assigned to the “Pair” push-button.
Briefly pressing the button (tap) activates the status LEDs for approx. 30 minutes.
A long press of the button (≥ 10 seconds) activates Pairing.
Deactivation takes place automatically when you exit the Pairing mode on the master gateway.
A long press of the button (approx. 3 seconds) activates Bluetooth. The status LED L2 flashes green. The unit remains visible for approx. 60 seconds and can be detected by the Lumenradio W-Modbus app. The connection remains active until you press “Disconnect” in the app or activate Pairing mode on the unit.
For more information, see “Configuration” (W-Modbus app).

PAIRING “Slave”
The bus address is set to “1” at the factory and can be changed using DIP switches (see “Modbus configuration” section).
The bus address can be changed at any time, even after pairing to a gateway.
To pair a W-Modbus sensor (slave) to a master gateway (DDC/PLC), both units must be set to Pairing mode. This also applies if the unit needs to be integrated into an existing network. Nodes that have already been paired are also automatically set to Pairing mode and paired again. Only one master gateway may be in Pairing mode at any one time in the immediate vicinity (wireless range)!
The W-Modbus sensors (slave) – hereinafter referred to as the sensor – are paired in three simple steps:

Activate pairing (open the connections)

The sensor is automatically set to Pairing mode at the factory.
Manual activation is performed by pressing the “Pair” push-button (long push of button for ≥ 10 seconds).
The status LEDs indicate that Pairing mode is active: L1 flashes red, L2 is turned off.
On display units, [PAIRING] is shown alternately with the configured bus address.
Please refer to the unit-specific operating instructions for the procedure for activating or deactivating Pairing mode on the master gateway (DDC/PLC).

Pair the units (set up a connection)

When Pairing mode is active, the sensor automatically searches for a gateway that is set to Pairing. This process can take approx. 1 – 2 minutes.
The status LEDs indicate the running processes: L1 flashes red – L2 is lit red [PAIRING] is shown first on display units.
The status LEDs then indicate successful pairing: L1 flashes green – L2 is lit green or orange (depending on the quality of the wireless connection).
On display units, [CONNECTED] is shown after successful connection.
Note! If the unit is paired with a master gateway from a third-party provider, the status LEDs indicate using different colours: L1 continues flashing red – L2 is lit green.[PAIRING] remains showing on the display.
Now there is a temporary connection that can be secured as described in step 3.
After approx. 2 – 3 minutes, you can already test the Modbus communication and exchange data in this phase.

Deactivate pairing (secure the connections)

After all units have paired successfully, the user must manually terminate pairing on the master gateway. This also terminates pairing on all paired units.
The sensor then performs an auto-restart and a secure connection is established. Modbus communication is re-established within 2 – 3 minutes.
The status LEDs indicate the ongoing restart: first, L1 and L2 turn off.
On display units, [NO NETWORK] is shown briefly.
The status LEDs then indicate that the connection is secure: L1 is lit green –L2 is lit green, orange or red (depending on the quality of the wireless connection).
On display units, [SECURED] is shown after the connection is secured.
A permanent connection is now established and remains even after the unit is restarted. Data exchange can begin in standard mode.

NOTES
Status LEDs turn off (LED L1 and L2 turn off)

LEDs deactivate automatically after a 30-minute time-out.
The LEDs can be reactivated using the pair button (short push of button).
Error message (LEDs L1 and L2 flashing red – Display units show [W-M ERR!].)
Perform a reset: disconnect the unit from the power supply for approx. 1 minute, then switch it on again. If the error persists, please contact S+S Technical Support.

General bus topology structure with terminating and bias resistors (Mixed configuration)

THERMASGARD-36600-2025-Temperature-Measuring-
Transducer-7

The W-Modbus protocol is based on the 2.4 GHz ISM radio band and employs a patented frequency hopping technology to maximise reliability and resistance to interference.
This means that reliable radio transmission can also be ensured in industrial environments.
In the W-Modbus network, up to 100 nodes can communicate with each other over a long distance of up to 500 m (open field) using one gateway. A standardised W-Modbus module ensures compatibility with all W-Modbus units.
The W-Modbus sensors only need to be supplied with power. Only the slave address is configured manually, the transmission parameters (baud rate and parity) are set automatically. No terminating resistor is required.
The sensor is then paired with a gateway.
The W-Modbus gateway can be installed anywhere along the Modbus line. It serves as a junction between a wired
Modbus and radio-based W-Modbus. Even mixed configurations of wired and radio- based Modbus units can be easily integrated into existing network topologies via the W-Modbus gateway.

BUS ADDRESS
The bus address is set to „1“ at the factory and can be changed using DIP switches.
The bus address can be changed at any time, even after pairing to a gateway.
With display units, the modified bus address is shown on the display for approx. 30 seconds.

Configuration using „193“ as an example

THERMASGARD-36600-2025-Temperature-Measuring-
Transducer-8

The device address in the range of 1 to 247 is set at DIP switch [A].
For switch positions 1 to 8 see the table on the back!
Address 0 is reserved for broadcast messages. Addresses greater than 247 must not be assigned and are ignored by the device. The DIP switches are binary- coded with the following values:

DIP 1 = 128…………. DIP 1 = ON
DIP 2 = 64…………. DIP 2 = ON
DIP 3 = 32…………. DIP 3 = OFF
DIP 4 = 16…………. DIP 4 = OFF
DIP 5 = 8…………. DIP 5 = OFF
DIP 6 = 4…………. DIP 6 = OFF
DIP 7 = 2…………. DIP 7 = OFF
DIP 8 = 1…………. DIP 8 = ON

The switch positions shown here result in the Modbus address 128 + 64 + 1 = 193

BUS PARAMETERS
The bus parameters for W-Modbus sensors are automatically configured.
The required settings (e.g. baud rate) are made directly on the W-Modbus gateway.

DIAGNOSTICS
Integrated fault diagnostics function (see „Function 08 Diagnostics“ table)

APP MODE

The Lumenradio W-Modbus app can access W-Modbus units.
To do this, Bluetooth must be activated manually on the unit (using the „Pair“ push-button). The unit then becomes visible and can be connected via the app.
For further information, see „Commissioning“ („Pair“ push-button)

In App mode, the Lumenradio W-Modbus app can access the gateway:

Firmware updates of the wireless module
Error detection (duplicate bus addresses, communication errors, etc.)
Individual unit names
Checking the network setup
Documentation of the network setup (PDF)

You can find more information via the help function in the app.
The app is available for Android and Apple mobile devices through the app store.

READOUT IN THE DISPLAY

The display value depends on the set unit system (see table “Function 05 Write Single Coil”).
If required, the unit can be switched from SI (default) to imperial units.

Standard display
By default, the first line indicates the value while the second line indicates the corresponding unit statically: temperature [°C] [°F]. Resolution is 1/10 of values.

Error display
Sensor breakage and sensor short circuit are detected and reported as an error, which is indicated on devices equipped with a display. The error status can also be retrieved by means of a bus query.

THERMASGARD-36600-2025-Temperature-Measuring-

Freely configurable display (Tyr 3)
The Modbus interface allows the display screen to be individually configured, both in the 7 segment range and in the dot-matrix range. This means that messages such as those from the PLC can be displayed.

For the individual display, the register 4×0001 (physical display value) must contain the value 10.
The registers 4×0002 to 4×0022 contain information about the characters and segments to be displayed. The two left-aligned positions are represented by the register 4×0003 (range -9…99). The value 0 switches off the display of both positions. The display is only active if the register 4×0002 has positive values.

In the default setting (register 4×0001 contains the value 0 for the standard display), even the characters I-Q (registers 4×0014 to 4×0022) are freely programmable in the dot-matrix range.
In this case, the current measured value is automatically displayed in the 7-segment area.
