kiWi (or '''ki''''conex '''wi''''reless) is our solution for transforming controls with modbus RTU communication to modbus TCP/IP communication. This communication allows to connect devices wirelessly to the local ethernet network of the installation where the main '''kiBox''' is located.

Information about [[kiWi 2023]].

=== Description of the kiWi solution ===
In a conventional facility with Modbus RTU communication, all devices have to be wired directly to the Modbus master (''kiBox'') using a 2-wire shielded cable. This connection is made using daisy-chain connection type. It can be seen in more detail in this

The ''KiWi'' solution allows to transform the modbus RTU communication to a wireless modbus TCP/IP connection. In this way, the local WiFi network of the facility can be used to connect the different control-devices. In addition, since the ''KiWi'' device also has an RJ45 port, it can also be connected to the local Ethernet network via Ethernet cable through the RJ45 connector.
Example of a conventional installation with Modbus RTU communication:

It should be noted that a ''kiWi'' can connect up to a certain maximum number of devices, which will depend on the number of variables available on the devices and the configuration speed of the bus.

=== Configuration of the ''KiWi'' ===
Default configuration:

* WiFi: '''KIWI_XXXXXXXXXX'''
* WiFi Password: '''123456789'''
* IP configuration portal: '''192.168.4.1'''
* Portal password: '''123456789'''

===== Configuration parameters =====

* WiFi network SSID
* WiFi network password
* Free IP for the kiwi
* Gateway
* Netmask
* DNS1 and DNS2

===== Operating Notes =====
''KiWi'' creates its own WiFi network, of type KIWI_58AEB3J2, in the following cases:

* Not configured
* Wrong configuration
* Network disconnected



If you have already configured the ''KiWi'' , you can access it by connecting to the same network and typing its IP in the browser.

Versions prior to v1.3.5 only support Modbus RTU 9600 baud 8N1 and Modbus TCP communications through port 502.

You can check the version in the information window of the ''KiWi'' web portal.

==== Access to the ''KiWi'' configuration portal ====

<span id="Acceso_a_KiWi_no_configurado"></span>
===== Access to ''KiWi'' not configured =====

# Connection to ''KiWi'' WiFi network from smartphone.[[Archivo:SP - Captura red wifi del kiwi.jpg|centro|marco|Example of kiwi wifi network visualization]]
# If you have not been redirected to the configuration portal you must open Chrome, Firefox or similar browser.[[Archivo:SP - Navegadores.jpg|centro|miniaturadeimagen|800x800px|Browsers]]
# Access the IP 192.168.4.1
[[Archivo:SP - Captura de pantalla IP del kiwi.jpg|centro|marco|Access to KiWi by IP]]

===== Access to ''KiWi'' already configured =====
The process of the previous section is repeated, but in this case it is necessary to connect to the same WiFi network that was configured in the ''KiWi'' , and the IP to enter in the browser is the IP that was configured in that kiwi.

# Confirmation of entered parameters. If you want to change any of them, you can go back. [[Archivo:SP - Confirmación de la configuración RS-485 en configuración del KiWi.png|centro|marco|Confirmation of RS-485 configuration in KiWi configuration]]
# End of configuration. [[Archivo:SP - Fin de la configuración en connfiguración del KiWi.png|centro|marco|End of the configuration in KiWi configuration]]



If during the life of the ''KiWi'' , the network to which it is connected is modified, it will be necessary to reconfigure ''KiWi'' for the new parameters that characterize the network.

When ''KiWi'' has problems connecting to a network, it continuously retries by keeping its WiFi access point open when accessing to verify its configuration and change it if necessary.

===== Deletion process =====
If you need to delete the configuration set in ''KiWi'' , you can do it in two ways:

<div class="mw-translate-fuzzy">
# If you have access to the configuration portal, at the end of the information window there is a deletion option: [[Archivo:SP - Proceso de borrado del KiWi.png|centro|marco|KiWi deletion process]]
# In case you do not have access to the portal, you can delete the configuration manually through the reset button located in the hole on the top cover of the '''KiWi'''. It is necessary to insert a very narrow element and hold down the button for about 10 seconds.
