Introduction to the cLAN-MQ

Purpose of this manual

The purpose of this manual is to provide the instructions to quickly and easily install and operate the

cLAN-MQ

The installation of the cLAN may implies the installation an MQTT broker

Telemetry and control solutions with cLAN

The cLAN-MQ has multiple uses. These are the most common uses that will guide you to read this

manual.

Ethernet RTU/Datalogger to MQTT broker

Physical inputs/outputs

Modbus inputs/outputs (embedded Modbus master)

Serial port data (using script programming)

Local input/output control (using script programming)

Publish current values (reports) and timestamped values (historics) using MQTT

Receive commands/order from the MQTT broker using subscription

RTU/Controller accessible by Modbus TCP and RTU/ASCII

Physical inputs/outputs

Serial port data (using script programming)

Modbus protocol to read input/outputs remotely

RTU/Controller with SNMP agent (V1)

Physical inputs/outputs

Modbus inputs/outputs (embedded Modbus master)

Remote Access to serial port

Remote serial port via MQTT broker

Programmable protocol converter

Serial port data (using script programming)

Direct connection to SCADA using its Modbus TCP/RTU slave

Ethernet RTU/Datalogger to MQTT broker

There are hundreds of types of sensors that can be contacted directly to the cLAN-MQ inputs to

measure different types of variables. Depending on the cLAN-MQ model, sensors could be used to

deliver signals in 0-10V, 4-20mA or pulses, or simply connect different devices to their inputs/outputs. The

cLAN-MQ can also be configured as Modbus master and queries can be made to different slaves to

expand its inputs/outputs.

The cLAN works as a datalogger, creating records with timestamp with the value of the built-in or external

I/Os and publish them to the broker

The cLAN can also be used to do a local control over its inputs/outputs using the script programming

feature.

Nota: Exemys does not provide the MQTT broker

For this type of solution the following procedure must be followed:

Have an MQTT broker available

Install the cLAN.

Install the configuration software (“GRD Config”), this application will allow us to configure all cLAN

parameters locally or remotely.

Establish a connection between the cLAN-MQ and the broker

Configure the inputs/outputs in the cLAN according to their use:

Physical inputs/outputs

External Modbus inputs/outputs.

Configure the cLAN-MQ serial port.

Configure the “Embedded Modbus master" and the queries we want it to make.

Configure the topics and formats to publish an enable reports and historicals to publish

RTU/Controller with SNMP agent (V1)

The cLAN can work as a SNMP agent. This allows the user to get the valor of the digital an analog

channel from a SMNP manager.

It can send SNMP traps also. They can be triggered by a change on a digital input or if an analog input

goes over a high/low value.

For this type of solution the following procedure must be followed:

Install the cLAN.

Install the configuration software (“GRD Config”) V9.1+, this application will allow us to configure all

cLAN parameters locally or remotely.

Configure the inputs/outputs in the cLAN according to their utilization:

Physical inputs/outputs

External Modbus inputs/outputs.

Configure the cLAN serial port.

Configure the “Embedded Modbus master" and the queries we want it to make.

Enable traps in case your SNMP manager can handle them

Configure SNMP communities

Remote serial port

This procedure will allow you to send and receive data to and from the serial port (RS232/RS485) using

publish and subscribe.

For this type of solution the following procedure must be followed:

Install the cLAN.

Install the configuration software (“GRD Config”) V9.1+, this application will allow us to configure all

cLAN parameters locally or remotely.

Establish a connection between the cLAN-MQ and the broker

Configure the serial port in Remote mode

Configure the serial ports publish and subscribe topics

Programmable protocol converter

Using script programming is possible to use the cLAN as a protocol converter. It can be programmes to

parse new protocols over it's serial port. The acquired data can be read using Modbus RTU/ASCII on

the other serial port, por Modbus TCP on its Ethernet interface. Some typicall aplications are using the

cLAN to get Modbus data from scales, water quality analyzers, oil quality analyzers, card readers,

weather stations, etc.

Read the "cLAN Model" section to get serial ports, inputs/outputs and power wiring.

Wiring – Ethernet Port

The cLAN's Ethernet port is a regular 10/100 Mbps port (10BASE-T / 100BASE-TX)

LED Indicators

The cLAN has 3 LEDs indicators.

PWR: Power applied to the GRD

Network (yellow) : State of Ethernet port and IP configuration

LINK (green) : State of the connection between the cLAN and the Middleware

We find below the detail of the indication of each LED independently and in combination.

cLAN-MQ configuration software – GRDconfig

GRDconfig is the application program used to configure the cLAN-MQ equipment.

This application was developed with an easy-to-use feature in mind to configure and monitor the cLAN-

MQ and the GRD devices.

The Configurator is supported on the following platforms: Windows 2003, XP, Vista, 2008, 7, 8 and 10

(32 and 64 bits).

Java Runtime Environment 1.8 (32 bit version) must be installed (available free in www.java.com).

Installation

For installation follow these steps:

Run the installation software (www.exemys.com/grdconfig)

A welcome screen will be displayed, then follow the instructions of the Installation program which will

request the necessary information to complete the installation. Click on “Next” to continue.

Destination folder: Select the folder for the installation of the application program.

Wait for the installation program to copy all necessary files onto the hard disk, and press “Finish” to

end the installation process.

Once installed you will see in the Programs menu a folder called Exemys. Inside the folder you will find

another folder called GRDconfig; this folder contains the GRDconfig and Uninstall icons and the Script

Programmer folder.

General description of the Configurator

The following figure shows the main screen of the Configurator.

Configuration cLAN-MQ's network parameters

The cLAN-MQ can be configured locally through its Ethernet port. Before connecting the GRDconfig

with the cLAN-MQ you must configure its network paramaters (IP address, Net mask, Gateway, etc)

Press the triangle on the right of the "Connect" button and select "Open Ethernet Connection"

If there are cLAN-MQ devices connecter to your local network they will be listed, showing their IP

address. If the device doesn't have an IP address yet it will show (0.0.0.0)

If you press the "config" button you will be able to see/edit the device network configuration

If you enable DCHP and there's a DHCP server on your network, these parameters will be assigned

automatically.

If you configure the parameters manually, have in mind that the Gateway is only necessary if the MW if in

the different network that the cLAN-MQ. DNS1 and DNS2 are only used if the MW's is located using a

URL instead of an IP address.

If you are not using the Gateway or the DNS you can set them at 0.0.0.0

When changing these values the GRDconfig will ask you for a password. This password is configured in

the "Advanced" section on the MQTT tab. Factory default is a blank password.

Establishing a local connection with the cLAN-MQ

To establish a local connection with the cLAN-MQ (LAN/Ethernet), your computer and the cLAN-MQ

mus be connected to the same network.

As described in the previous paragraph, search the cLAN-MQ pressing the Connect button (after

choosing "Open Ethernet Connection") and then double click on the cLAN-MQ you wan to configure.

The GRDconfig will prompt a password. This password is the same the cLAN-MQ uses to connect to the

MW. Factory default is a blank password.
