LumenRadio W-Modbus Manual

MANUAL W-Modbus and W-Modbus PRO
APPLICATION AREA
The W-Modbus product transmits Modbus RTU frames wirelessly. It is designed
to be used indoors only. If used outdoors, this unit must be installed in a protec-
tive enclosure with minimum IP65 rating. The product is intended to be used as
a Modbus RTU cable replacement.
GENERAL
This manual applies for both the DIN rail and the wall mounted version of the
W-Modbus product. All relevant personnel must acquaint themselves with these
instructions before installation. Warranty is voided if the product is not hand-
led accordingly with the outlined instructions. Any damage to the product or
parts due to improper handling will void the warranty. Do not use the product if

ELECTRICAL SAFETY
Only qualified electricians or service personnel trained by LumenRadio may per-
form interventions in connection with electrical installation. Always follow local/na-
tional rules when performing this type of electrical installation. When connecting
a 24 V isolation transformer, this must be done in accordance with IEC 61558-1.

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. 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.
3. 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.
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. Check that the W-Modbus unit and its wiring are securely mounted (if the
unit is powered this will be indicated by the LEDs).
6. 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 con-
nected 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.
2 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
2
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 rectified 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 connection and connection for Modbus RTU communi-
cation via RS485. The W-Modbus DIN rail units have an 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.
