'''Modbus''' is a serial communications protocol. Simple and robust, it has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.
'''Modbus''' is a serial communications protocol. Simple and robust, it has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.
In this configuration example, we will configure Modbus TCP Slave and Modbus TCP Master. We will send a Set Parameters request from Modbus TCP Master to Modbus TCP Slave, which will send an SMS message provided in the Modbus TCP Master Set PArameter request.
In this configuration example, we will configure Modbus TCP Slave and Modbus TCP Client. We will send a Set Parameters request from Modbus TCP Client to Modbus TCP Slave, which will send an SMS message provided in the Modbus TCP Client Set Parameter request.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should '''turn on "Advanced WebUI" mode'''. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.

Firstly, we will configure '''Modbus TCP Slave''' on the router and then on the same device we will configure '''Modbus TCP Master''' in order to send Modbus requests to the same device.
Firstly, we will configure '''Modbus TCP Server''' on the router and then on the same device we will configure '''Modbus TCP Client''' in order to send Modbus requests to the same device.

# Enable the Modbus TCP Slave
# Enable the Modbus TCP Server
# Select the port on which Modbus TCP Slave will communicate with the Modbus TCP Master (for this example: 502)
# Select the port on which Modbus TCP Server will communicate with the Modbus TCP Client (for this example: 502)

===Configuring Modbus TCP Master Request Configuration===
===Configuring Modbus TCP Client Request Configuration===
Now that we have '''Modbus TCP Master''' and '''Modbus TCP Slave''' configurated, we will need to create '''Request Configuration'''. The Request configuration will be used to store the SMS message and the number of the recipient. Lastly, we will send the SMS message to the recipient with the set Command.

The Request configuration will be used to store the SMS message and the number of the recipient. Lastly, we will send the SMS message to the recipient with the set Command.
To store Phone numbers and SMS messages we will use '''ASCII''' and/or '''HEX''' Data Types, you can configure either one of them, and both of them will work.

So first of all, we will create a Request in which we will store the Recipient number and SMS message, we will use '''ASCII Data Type''', '''Set Multiple holding registers(16) Function''' and '''398 Register'''.

Lastly we will need a Request which would send the text message that we loaded previausly, to do so you will need to create a send Request. The Send Request should look like this:

Execute the first request, if everything was configurated correctly you should receive the confirmation message after that execute the '''Test_send''' request which will send the message to your phone number.
