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
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 con-
nect multiple devices located in close proximity to each other.
W-Modbus and W-Modbus PRO are fully compatible and can be mixed
in 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.
1. Confirm that the W-Modbus unit has no visible damage.
2. The W-Modbus enclosure is wall mounted and fits onto a junction
box. Start with mounting the backplate of the enclosure.
3. 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.
4. 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.
5. Secure the front plate to the mounted back plate.
6. 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 internal termination resistor.

POWER AND RS485 CONNECTION
The W-Modbus units have 24 VAC/VDC power in/out connection and con-
nection 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 de-
vice also sharing a 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.
