SYSTEM OVERVIEW
A W-Modbus network consists of a single W-Modbus Gateway connected to the
Modbus Client using an RS485 cable, and up to 100 W-Modbus No- des, each of
them connected to one Modbus Server over RS485. 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
address. The scanning is done by querying each Modbus address, hence the
process may take up to 2 minutes. If the W-Modbus Node cannot find the
connected Modbus Servers address, it will not be reachable by the Modbus
Client connected to the W-Modbus Gateway.
If adding, removing, or changing the Modbus address of the connected device,
double press the push button to initiate a new scanning.
W-MODBUS PRO
With the PRO version of W-Modbus, up to four Modbus Servers can be connected
to one W-Modbus PRO Node – making it even easier to connect multiple devices
located in close proximity to each other.
W-Modbus and W-Modbus PRO are fully compatible and can be mixed into a system.
All instructions below apply to both models.
The label on the back of the product shows the product type: W-Modbus or
W-Modbus PRO.
INSTALLATION
Install the W-Modbus unit next to the device it should be connected to.
- Confirm that the W-Modbus unit has no visible damage.
- The W-Modbus enclosure is wall mounted and fits onto a junction box. Start with mounting the backplate of the enclosure.
- Connect the power supply and the Modbus device to the W-Modbus unit, as shown to the right. 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.
- Secure the front plate to the mounting back plate.
- Check that the W-Modbus unit and its wiring are securely mounted (if the unit is powered this will be indicated by the LEDs) The device is now ready for commissioning.
W-Modbus is an end device with an internal termination resistor.
POWER AND RS485 CONNECTION
The W-Modbus units have 24 VAC/VDC power in/out connections and connections
for Modbus RTU communication via RS485.
WARNING: When powering the W-Modbus device using 24 VAC, the power
supply/transformer should not be shared with another Modbus device also
sharing an RS485 connection. This is to avoid ground loops caused by the use
of different types of rectification in the devices. W-Modbus uses full wave
rectification.
BAUD RATE, PARITY, AND STOP BIT
Set the baud rate, parity, and stop-bit configuration on the DIP switch 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, the different configurations can be used on the Nodes – effectively
mixing configuration within the network. Use the 5th DIP switch to override
the global configuration and use a local configuration set on the Node. |

COMMISSIONING
The commissioning process is used to connect the W-Modbus devices to the same
wireless network. All W-Modbus devices will come from the 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.
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.
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.
-
Start by selecting which device to use as the W-Modbus Gateway and position the 3 pole switch in the middle position. This unit will reboot into Gateway 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 Gateway. This process takes a few minutes. Nodes further away will connect to a closer W- W-Modbus Node if the Gateway is out of reach. When a Node is connected it will be indicated by 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 secure mode and be ready for operation. From now on the LEDs will indicate status in accordance with the system status section.
TROUBLESHOOTING
Does the unit have power?
Press the push button, if the LEDs are not switched on, check the power connection.
Is the unit connected to the network?
Check the Wireless Network status LED. A Node with a flowing blue light is not connected to the network. Reference the commission section to ensure the unit indicates connection before switching the Gateway into secure mode. If the flowing blue light persists the unit is out of range from the network. Try installing an extra W-Modbus unit in between for better wireless coverage.
Is the network within the limits of the maximum (100) Nodes allowed?
Make sure no more than 100 Nodes are connected to one W-Modbus Gateway. If
more than 100 Nodes are needed, another W-Modbus gateway is required. Set it
up in the same way as before.
If the Wireless Network Status indicates a bad wireless network (red LED) make
sure the distance between W-Modbus units is within the requirements or add an
extra W-Modbus inbetween to get better wireless coverage
If the Communication 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.
All Nodes are connected during commissioning (all LEDs flash green) but not
all Nodes rebooted to the secure network when the Gateway was set to secure
network. Make sure only one unit is set to Gateway mode during commissioning.
It is only possible to install one network at a time.
