MODBUS PROTOCOL

MODBUS Protocol is a communication structure used to establish master-slave/client-server communication between
intelligent devices connected on different types of buses or networks.
Each device intended to communicate using Modbus is given a unique address. Master devices send a command in a frame
which contains the address of the device or the end-devices (slaves). All devices are sent the frame, but only the recipient
interprets and executes the command. Modbus commands contain checksum information, to allow the recipient to detect
transmission errors.
Note: It possible to send information to multiple devices simultaneously using a frame called "Broadcast".
Each message includes redundant information that ensures it is properly received. If, after a certain time, the master does not
receive a confirmation it interprets that an error has occurred and terminates communication.
The mode of transmission used is MODBUS-RTU. Each byte of data is represented by two 4-bit characters in hexadecimal format.
The format of the frame is the following:

DKN WI-FI CONTROLLER

The DKN is a Modbus slave device, so it is necessary to indicate its address. To do this, associate your DKN via the "DKN NA"
app (available for iOS and Android) by following these steps:
On the drop-down menu press the option Add device.
1.
Select the unit from the list of available units to get info.
2.
Note: If your unit does not appear, confirm the Bluetooth function of your iOS or Android is activated.
Verify that the DKN is working properly.
Enter the pin code located in the DKN if required and tap Send button.
3.
Enter the Communication protocol > Modbus (slave address) to with you want to point within
