- Wall mount: The enclosure is wall mounted and fits onto a junction box. Start with mounting the backplate of the enclosure. DIN rail: The DIN rail has a clip-on mounting. Place it onto the DIN rail.
- Connect the power supply and the Modbus device to the W-Modbus unit, as shown to the right. For a wall mounted unit, use the rear and/or top knockouts for cable entry.
- All W-Modbus units are factory set for Node operation, without the need for additional configuration. If mixing serial configuration in the system, adjust the dip switches accordingly.
- Check that the W-Modbus unit and its wiring are securely mounted (if the unit is powered this will be indicated by the LEDs).
- Wall mount: Secure the front plate to the mounted back plate.
The device is now ready for commissioning. W-Modbus is an end device with internal termination resistor.

SYSTEM OVERVIEW
The W-Modbus comes in three different versions; wall mount, wall mount PRO and DIN rail. A W-Modbus network consists of a single W-Modbus Gateway connected to the Modbus client using an RS485 cable. It can be up to 100 W-Mod-bus Nodes in one network, each of them connected to one Modbus server over RS485, or in the PRO case, up to four Modbus servers on one wall mount PRO. Every device can act as either a Gateway or a Node, selectable by the 3-pole switch – see Commissioning section. Each W-Modbus Node will scan to find the connected Modbus servers’ Modbus addresses. The scanning is done by querying every Modbus address, hence the process may take up to 2 minutes. In this case, the W-Modbus Node will indicate red on the data LED – see System mode and status
POWER AND RS485 CONNECTION
The W-Modbus uses a half-wave rectifier circuit. It should not share a
transformer with a full wave rectified VAC source. The W-Modbus wall mount
units have 24 VAC/VDC power in/out connections and connections for Modbus RTU
communication via RS485. The W-Modbus DIN rail units have a 12-24 VDC or 24
VAC connector at the top of the product next to the external antenna and an
RS485 connector at the bottom.
BAUD RATE, PARITY AND STOP BIT
- Set the baud rate, parity and stop bit configuration on the DIP switches to match the configuration of the connected Modbus device. The possible combinations can be found in the table to the right.
- The configuration on the W-Modbus Gateway is global and will be synced to all connected W-Modbus Nodes, meaning the W-Modbus Gateway is the only device that needs to be configured as long as the same configuration is used in the entire network.
- If needed, different configurations can be used on the Nodes – effectively mixing serial communication settings within the network. Use the 5th DIP switch to override the global configuration and use a local configuration set on the Node.
COMMISSIONING
All W-Modbus devices will come from factory uncommissioned in Node mode. If the same configuration is used in the entire system, the W-Modbus Gateway is the only device that needs to be configured, the Nodes will automatically be configured when connecting to the Gateway. Mount and power up each device before starting with step 1 below.
- Start by selecting which device to use as the W-Modbus Gateway and posi-tion the 3 pole switch in the middle position. This unit will reboot into Gate-way Commissioning mode. The device will indicate the mode by a green flow of LEDs. In this step also adjust the DIP switch to the correct baud rate, parity and stop bit(s).
- All powered W-Modbus Nodes within range will now connect to the Gate-way. This process takes a few minutes. Nodes further away will connect to a closer W-Modbus Node if the Gateway is out of reach. When a Node is connected it will be indicated be a synchronous green blink on all three LEDs.
- Check that all Nodes installed are indicating connection, and then set the 3 pole switch to the bottom position on the W-Modbus Gateway. Now the entire network will reboot into the secure mode with all three LEDs blink-ing yellow in sync on all the connected servers. From now on the LEDs will indicate status in accordance with the system mode and status section.
TIP: It is possible to add a new node to an existing system. Just mount
and power up the device as usual, then redo the commissioning starting from
step 1 for the new Node.
TIP: To speed up the connection process, set the device intended to be
Gateway in Commissioning mode before mounting the nodes. In that way they will
connect as soon as they are powered, and the waiting time in step 2 above is
reduced.

SYSTEM MODE AND STATUS
Node signal strength indicates the Nodes mesh network performance. A green LED
means that the Node has a strong signal to it’s parent Node in the mesh
network. A yellow LED indicates that you have a normal mesh network
performance, no need to change position or add an additional Node. If your
Node indicates red it means it has difficulties getting the signal to the next
Node in the network but it is still working. It is recommended to either
change position or add an additional Node to the network. The Node will blink
yellow if it has lost the network and searches for it.
TROUBLESHOOTING
-
The LEDs suddenly go out.
The LEDs turn off after 30 minutes, press the button once to turn on for another 30 minutes. If you hold the button for five seconds the LEDs will always be on. -
Does the unit have power?/How do I see that the unit is powered?
Press the button, if the LEDs are not switched on, check the power. -
Is the unit connected to the network?
Check the Mode/Network LED. A steady green, yellow or red mean that a Node is connected. A Node with a flowing blue light is not connected to the network. Refer to the commission section to ensure that the unit indicates connection be-fore switching the Gateway into Secure mode. If the flowing blue light persist the unit is out of range from the network. -
My Modbus communication is not working.
If the Data LED indicates no communication (red LED) check if the RS485 cable is correctly installed and make sure the baud rate, stop bit and parity settings are correct. If all is correct and Modbus data is being transmitted, you should see green (TX) and blue (RX) LED flashes on the TX/RX LED. The data LED will also be steady green.
