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
