Introduction
Congratulations with your x-Messenger SMS/GSM/GPRS Micro-PLC provided by Rievtech
Electronic Co., Ltd.
The x-Messenger is a compact and expandable telemetry module combining industrial
grade GSM/GPRS modem, PLC controller, data logger, Ethernet module, and multiple
communication capability (1RS232&1RS485 ,MODUS ASCII/RTU/TCP, Mater/Slave).
Each module incorporates not only a real-time clock and calendar, but also provides
support for SMS, Call-In,Email, Ring and optional expansion digital /analog -I/O modules
and to enhance control and monitoring applications. Data adjustments can easily be
performed via the keypad, the LCD display, or through the easy-to-use eSmsConfig.exe.
DIN-rail and panel-mounted options are both available, offering full flexibility to the
various installation needs of your application.
The x-Messenger is available in 120V/240V AC or 12V and 24V DC versions, making it the
ideal solution for relay replacement, or simple control applications with SMS control or
alarming such as building and parking lot lighting, managing automatic lighting, access
control, watering systems, pump control, ventilation systems, home automation and a
wide field of other applications demanding low cost to be a primary design issue.
We strongly recommended taking the time to read this manual, before putting the
x-Messenger to work. Installation, programming and use of the unit are detailed in this
manual. The feature-rich x-Messenger provides an for off-line operation mode, allowing
full configuration and testing prior to in-field service commissioning. In reviewing this
manual you will discover many additional advantageous product properties, which will
greatly simplify and optimize the use of your x-Messenger.

The manual applies to devices of EXM series modules. For more information about
expansion module or accessories, please refer to the correlative model instruction files.
Safety Guideline
This manual contains notices you have to observe in order to ensure your personal
safety, as well as to prevent damage to property. The notices referring to your
personal safety are highlighted in the manual by a safety alert symbol; notices referring
to property damage only have no safety alert symbol. The notices shown below are graded
according to the degree of danger.
Caution
Indicates that death or severe personal injury may result if proper precautions are not
taken
Caution
With a safety alert symbol indicates that minor personal injury can result if proper
precautions are not taken.
Caution
Without a safety alert symbol indicates that property damage can result if proper
precautions are not taken.
Attention
Indicate that an unintended result or situation can occur if the corresponding notice is
not taken into account.
If more than one degree of danger is present, the warning notice representing the
highest degree of danger will be used. A notice warning of injury to persons with a safety
alert symbol may also include a warning relating to property damage.

Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation.
Commissioning and operation of a device/system may only be performed by qualified personnel.
Within the context of the safety notices in this documentation qualified persons are defined as
persons who are authorized to commission, ground and label devices, systems and circuits in
accordance with established safety practices and standards. Please read the complete operating
instructions before installation and commissioning.
GSM network failure or power interruptions cannot guarantee a secure monitoring. The use of a
prepaid SIM card is possible. It is recommended to use a SIM card with subscription.
This avoids possible credit balance problems. The individual responsibility for protecting the SIM
card against abuse lies solely with the card owner. EASY does not accept any liability for possible
damage to persons, buildings or machines, which occur due to incorrect use or from not following
the details.
Prescribed Usage
Note the following:
Warning
This device and its components may only be used for the applications described in the
catalog or the technical description, and only in connection with devices or components
from other manufacturers which have been approved or recommended by EASY. Correct,
reliable operation of the product requires proper transport, storage, positioning and
assembly as well as careful operation and maintenance.

Chapter 1 General Introduction to x-Messenger
1.1 Overview
Rievtech x-Messenger SMS/GSM/GPRS Micro-PLC with built-in GSM modem is a device dedicated for remote
monitoring, diagnostics and control of objects via short text messages (SMS) , E-mail or CLIP calls.
Configurable messages sent from the device with static (text) or dynamic (text and measured values)
content are a convenient way of passing important information to the monitoring center, or directly to the
defined phone numbers. SMS messages sending or Call-out can be triggered by change of binary input state,
reaching alarm thresholds, marker state change, counters and clocks. Industrial design, practical set of I/O
resources, easy to use configuration software tools and direct connection of sensors lowers the cost of
building system. There are 4 optional (0...10V DC) signal inputs or 2 (0/4…20mA) inputs built-in the CPU. So,
it can work with humidity sensors, water level sensor, pressure transducers, flow sensors, smoke, gas,
motion, shock and noise detectors, etc.
The device’s own phone book saves up to 50 mobile phone numbers of the receivers.
The programming of the x-Messenger is carried out with the eSmsConfig. Two programming modes are
available-standard and customized mode. All the settings can be configured very easy and without special
knowledge of any programming language in standard mode. In this way the settings can be configured
conveniently, flexibly and easily. Additional, Customized mode is supplied to users who are familiar with the
logic boxes of Boolean algebra, and moreover complex control, logic, timer, counter, analog math etc would
be needed for their systems.
*GSM network:850MHz, 900MHz, 1800MHz, 1900MHz (Quad-band GSM module inside)

Note: A. RS485 port can be used as either expansion or communication port, while serving as
communication port, EXM-E-RS485 communication module would be required as such port is not photo
electricity-isolated.
3.3 Resources
3.3.1 GSM /GPRS module built- in
Each x-Messenger CPU integrates an industry Quad-band GSM module inside. The x-Messenger can work
under the following GSM networks: 850MHz, 900MHz, 1800MHz, 1900MHz and will search these frequency
bands automatically.
Note: A. all the x-Messenger CPUs support the GSM function except the EXM-12DC-DA-RT-WIFI.
