WEMS MXThe most flexible I/O systemand BEMS in the world

wems.co.uk

© WEMS Limited 2016

Combining our robust wireless communications with a modular I/O system to deliver the most flexible BEMS in the world.

Why WEMS?The reason is simple - we researched, designed and

manufactured our I/O to work wirelessly right from the

start. Many manufacturers started with a wired system then

attempted to ‘fudge’ a wireless product into it...not WEMS.

Starting with wireless at the forefront of our thinking and then

adding in other elements afterwards has enabled us to develop

a system that works not just wirelessly, but wired, or in a hybrid

manner too.

Our R&D team have spent several years and millions of

pounds perfecting our wireless solution, culminating in a range

of products developed to work together, or with other BMS

systems seamlessly.

Site ManagersIntuitive, simple to configure BEMS designed for rapid roll-

out and requiring minimal training.

Wireless I/OOur new MX range can not only be wired or wireless, but

can be configured to use hybrid networks. This flexibility

allows an integrator to value-engineer jobs, install and

commission quicker, cover more difficult sites and cause

less disruption during installation.

BACnet Gateways BACnet Gateways allow integrators to utilise our robust

wireless I/O with their BMS platform of choice, whether it’s

Trend, Siemens, Schneider Electric or Tridium. Using our

I/O allows integrators to install and commission more sites

faster and with less disruption than ever before.

Install 30% faster.Complete more jobs.Gain an advantage.Grow your business.

in the UK

Why wireless?There are many misconceptions surrounding the use of wireless

I/O, namely that it’s too expensive and is only robust enough for

use in niche applications.

Our R&D team and our partners are dispelling these myths

and proving that wireless I/O is not only affordable, but gaining

in popularity. Our wireless I/O is now used in mainstream

applications such as retail stores, telephone exchanges, data

centres and transportation depots.

Benefits• Complete installations 30% faster

• Reduced out of hours working

• Reduced asbestos and safety risks

• Complete more installations due to less time on-site

• Less on-site disruption to client’s daily operations

WEMS MX - Site Managers

Site Manager 200Designed for larger sites, or more complex buildings, the Site

Manager 200 uses a powerful 1.6GHz Intel Atom processor,

combined with 2GB RAM and a 30GB SSD for optimum reliability

and speed.

The Site Manager 200 supports up to 250 wireless devices.

Site Manager 100Site Manager 100 is an ideal BEMS for a small to mid-sized site.

It operates using the same software as the Site Manager 200,

but has support for fewer wireless devices (suggested max. 16

controllers and 50 sensors).

The wizard-driven interface and relatively low cost make it ideal

for fast, multi-site rollouts that require less complex controls than

a standard BMS.

WEMS MX - BACnet Gateways

BACnet GatewaysOur BACnet Gateways allow systems

integrators to add WEMS wireless I/O into

3rd party BMS systems that are BACnet

compatible.

The Gateway itself acts as middleware

between the BMS platform and our

wireless modules and sensors.

The modules and sensors talk to the

Gateway using WEMS protocol, the

information sent is translated by the

Gateway and communicated back to your

BMS via BACnet, where all I/O appears

as native hardware.

Using a Gateway, systems integrators

can combine multiple different wireless

frequencies to suit different scenarios

and also mix wired comms with wireless

communications to create a system that’s

cost-effective for both the integrator and

client.

Gateway 200Our BACnet Gateway 200 allows any BACnet compatible BMS

to interface with the WEMS MX range.

The BACnet Gateway has a HTML5 user interface for discovering

and configuring MX I/O modules, sensors and any Modbus

points.

This discovery builds a table of I/O in the database, made-up

of analogue inputs/outputs, digital inputs/outputs and Modbus

points. The user can then simply use the standard BACnet

interface on a BEMS to discover the available I/O.

Supports systems with greater than 500 points.

Gateway 100The Gateway 100 utilises the same firmware as the Gateway

200, but is built to accommodate smaller sites with less

demanding I/O requirements and processing capability.

The Gateway 100 is a more affordable platform, ideal for

monitoring and controlling plant where wireless I/O is required,

but perhaps difficult to connect or extend with a wired solution.

Supports up to 500 points.

WEMS MX - An Introduction

WEMS MXThe MX I/O Range offers unprecedented flexibility to simplify installation and minimise overall installed cost.

The WEMS MX range of I/O is made-

up using clusters of DIN rail mounted

modules that plug together, like building

blocks. Each module is dedicated to an

I/O function i.e. digital inputs, thermistor

inputs, analogue inputs, analogue

outputs, relay outputs or communications.

This modular approach allows the user

to match the exact combination of points

required at each location.

Each cluster of modules requires a

Controller and a communications module,

which can be either wired RS-485, or one

of three wireless frequencies (434MHz,

868MHz or 915MHz).

Each cluster of I/O can use both wired

and wireless communications modules

concurrently to enable the creation

of a hybrid network. This mixing of

communications allows you to tailor

your systems to each building’s plant

and infrastructure and also allows you to

effectively value-engineer your projects to

deliver a faster, more efficient install.

Key Features:

• Concurrent wired & wireless comms

• Snap-fit modular I/O means no wasted

points

• Our wireless range is 2-3km line-of-

sight

• Routed discovery for hopped devices

• Compatible with WEMS Site Managers

and all BACnet compatible BMS via our

Gateways

• 128 bit wireless encryption

• Supports Modbus over wireless

Hybrid CommunicationsSupported by WEMS Site Managers or

Gateways, the MX modular range can

communicate wirelessly using 434MHz,

868MHz or 915MHz or alternately using

RS-485 for wired comms.

In the UK, Europe and many other

countries, 434MHz and 868MHz

frequencies are widely used and provide

fantastic wireless service.

The use of 868MHz frequency with an

amplification to 500mW (27dBm max)

power provides an optimum range.

Mixing these frequencies you can create a

long-distance backbone of up to 2-3 km

between wireless devices.

The adjacent diagram shows wired,

434MHz and 868MHz in a typical

arrangement.

915MHz comms modules are typically

used in North America only.


WEMS MX - Controllers

ControllerEach MX cluster must have a Controller,

which acts as a master, providing the

management of each module connected

to the cluster. Each Controller also

provides the power and communication

for the entire cluster via an intelligent bus.

Any combination of communication or

I/O modules can be connected together

in any order to tailor each cluster to meet

your requirements and the demands of

the building’s infrastructure.

Features• Pluggable, snap-fit modular system

• 2-part screw terminals

• DIN rail mount

• Status LEDs

Any combination of communication or I/O modules can be connected together in any order to make up a cluster to meet your requirements.

WEMS MX - Communications

CommunicationsAny cluster can have wired, wireless or

a mix of both communication types. You

can combine multiple wireless frequency

modules with RS-485 communication

modules into a single cluster.

This flexibility allows the cluster to

receive wirelessly and send out wired

communications to the next cluster or

vice versa. Any cluster can support any

combination of the modules listed here.

Integrators can combine multiple wireless frequency modules with RS-485 communication modules into a single cluster.

434MHzOur 434MHz narrow band wireless

module is 6.25mW (8dBm max) powered

and provides up to 2km line-of-sight

communications between wireless

devices.

868MHzThe 868MHz narrow band wireless

module supports amplification capable

of boosting the power output to 500mW

(27dBm max) and provides up to 2-3 km

line-of-sight communications between

wireless devices.

915MHzThis 915MHz narrow band wireless

module is 1dBm (-1dBm ERP max)

powered and provides up to 300 metres

line-of-sight communications between

wireless devices. Predominantly used in

North America.

RS-485Any cluster can have use an RS-485

module for traditional hard-wired

communications.

Communications from wireless modules

can also be hopped through the RS-485

module and vice-versa back to a Site

Manager or 3rd party BMS via a Gateway.

modules.

.Q Can you stack modules in a panel

and link them together to a single

Controller?

.A Yes. You can link modules on DIN rails

using an interconnecting lead.

.Q How many clusters can a Site

Manager support?

.A Up to 126 clusters of multiple I/O and

up to 128 sensors.

.Q What cable is required for the RS-

485 communications?

.A We recommend Belden 9841 or

equivalent standard.

.Q Will modules fit in a standard

consumer unit?

.A Yes. They have a footprint similar to

that of a single pole Miniature Circuit

Breaker (MCB), with each module

being 25mm wide.

.Q Are the products UL approved?

.A Yes. All MX modules & sensors meet

UL and CE approvals.

.Q Will your wireless system work in

an industrial environment?

.A Yes. We have many clients in all

sectors from telecoms, transport,

leisure, retail and large manufacturing.

.Q What are the signal ranges for the

wireless modules?

.A All signal distances are based on

line-of-sight and will be affected by

building materials if used internally.

• 434MHz can transmit up to 1km

• 868MHz can transmit up to 2-3km

• 915MHz can transmit up to 300m

.Q Can I combine any frequency of

wireless signal?

.A In North America there are regulations

permitting only 915MHz whereas in

Europe, Central & South America

and many other countries you can

combine 434MHz and 868MHz freely.

.Q Is there a specific order of modules

within a cluster?

.A The only requirement is that a

Controller must be used to provide

power and manage the other

modules. Apart from this you are free

to combine any type of modules in

any order up to a maximum of 20

modules.

.Q Can I extend the range of the

system further?

.A Yes, the range can be improved

by using clusters as repeaters. For

example, if a sensor was too far away

to communicate with a Gatweay

or Site Manager directly, it could

communicate to a closer cluster. This

cluster will then relay the data on

to the Gateway or Site Manager via

wired or wireless comms.
