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.
Page 3 cLAN-MQ User Manual Introduction 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.

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.
Page 8 cLAN-MQ User Manual cLAN 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.
Page 9 cLAN-MQ User Manual cLAN Configurator 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.

Page 20: Inputs/Outputs
cLAN-MQ User Manual Physical Inputs/Outputs Physical Inputs/Outputs Depending on the model, the GRD/cLAN can have or not physical inputs/outputs. We will now see the types of inputs/outputs that we can have and which parameters we can configure of each one. It is important to point out that this configuration is applicable only to physical inputs and not to inputs from the Modbus queries.
Page 21 cLAN-MQ User Manual Physical Inputs/Outputs The value of the anti-debounce can be configured between 1 and 250 ms. On devices with more than 8 digital inputs, inputs higher than 8 will have an anti-debounce time fixed at 250 ms. The counting divisor can take a value between 1 and 1000. On the cLAN2205-XF, cLAN2205-MQ, GRD3621-XF-3G, GRD3621-MQ-3G, GRD3625-XF-3G and GRD3625-MQ-3G you must configure wether a IO terminal will work as an input or as an output Take special care not to apply direct voltage to a terminal configured as an output and in ON state.

cLAN-MQ User Manual Embedded MODBUS master Configuration For GRD-3G, GRD-MQ, cLAN-MQ and cLAN-XF V2.0 + Embedded Modbus master (Input/Output extension) Depending on the GRD/cLAN model, it can have an internal Modbus master, which will allow you to increase the number of inputs/outputs of the device. We will now see the configuration and utilization. This master will let you load a maximum of 100 Modbus queries to which will be able to configure certain parameters.

Page 37: Channels
cLAN-MQ User Manual Channels Channels Channels are the media through which information about inputs/outputs of the MW (or broker) equipment are sent or received. These channels can be linked to physical entry points of the equipment like MODBUS queries according to their compatibility with the channel.
Page 38 cLAN-MQ User Manual Channels After selecting the desired channel and among any of the 4 you’ll have the option to add or remove, it is important to point out that within each channel only inputs and outputs compatible with that channel will appear.
Page 39 cLAN-MQ User Manual Channels To erase a channel you only have to click on the “Del” button of the channel previously selected. Since firmware GRD-3G 1.9+ and cLAN 2.8+ and new channel source called "Mem" is added This source is linked to a 100 position volatile memori that can be read and wrote from the script using read_io 305 and write_io 305 The signal level can be configured as analog channel source in GRD-XF-2G with firmware 4.0.0 or higher.
Page 40: Reports And Historical Records
cLAN-MQ User Manual Reports and Historical records Reports and Historical records - MQTT publish There are 2 types of information that the GRD-MQ/cLAN-MQ can send. On one side, we have the reports that contain the real values of inputs and outputs updated according to the criteria configured in the device.

Page 42 cLAN-MQ User Manual Reports and Historical records the first time it is connected, it sends a message with all configured reports. Digital inputs channels reports: The following figure shows the configuration screen of the digital inputs reports: Report by change If a report by change of a digital input cannel is enabled, a change of value will generate a message that will be sent to the broker.
Page 43 cLAN-MQ User Manual Reports and Historical records Report by change The report by change is enabled in the channels we want to be updated in the broker every time that the signal changes The "percentage" report will report if the input changes a percentage from full scale. The full scale value will depend on the input type.
Page 44 cLAN-MQ User Manual Reports and Historical records Pulse inputs channels reports: The pulse channels have 2 types of reports. On one side the reports by performed count and on the other the temporary report. Report by count In the counts number report the device sends a message to the broker each time the desired input counts a number of pulses from the last report of this channel, by counts or by time.

Page 46 cLAN-MQ User Manual Reports and Historical records By alarm This criterion defines an operational band through a maximum and minimum. When the analog input exceeds the maximum value a Historical is generated by maximum, when the analog input is lower than the minimum a Historical by minimum is generated and when the analog input passes from a maximum value or from a minimum value to a normal value between both a Historical by normal value is generated.
Page 47 cLAN-MQ User Manual Reports and Historical records It is not possible to configure a value of hysteresis greater than the difference between the maximum and minimum, and also a maximum smaller than a minimum. We can also associate a digital output channel to the alarm event by maximum and another one of alarm by minimum, this means that when the analog input in the maximum range will activate an output and in the minimum another one.
Page 48 cLAN-MQ User Manual Reports and Historical records Pulse input channels historical records The pulse channels can also generate Historicals in a specific time that can be configured the same way as in the other channels, as it is shown in the following figure. We can also decide if once the Historical is generated, we want the counter reset to 0 or not.
