Definición del mensaje (ModbusRTU-RS485)

=== Requisitos de cableado ===
* Uso de cable apantallado de 3 hilos libre de halógenos que otorgue protección contra interferencias en la comunciación Modbus RTU.
* Distancia de al menos 20cm con líneas eléctricas.
* Respetar la polaridad de cada conexión RS485
* Conexión entre equipos siguiendo una topología daisy-chain, como se muestra en la imagen siguiente:

* '''Común:''' en caso de disponer de conexión para cable común, del bornero (o del kibox) saldrá un cable que irá del común al común del primer control. Se conecta en el común y de ahí sale un empalme hacia el siguiente control. Se debe de repetir la operación como tantos controles se vayan a conectar juntos en el mismo puerto. El común 'morirá' en el último control de la serie.
* '''+ positivo:''' del bornero (o del kibox, según si existe cuadro eléctrico kiconex) saldrá un cable que irá del positivo al positivo del primer control. Se conecta en el positivo y de ahí sale un empalme hacia el siguiente control. Se debe de repetir la operación como tantos controles se vayan a conectar juntos en el mismo puerto. El común 'morirá' en el último control de la serie.
* '''- negativo:''' del bornero (o del kibox, según si existe cuadro eléctrico kiconex) saldrá un cable que irá del negativo al negativo del primer control. Se conecta en el negativo y de ahí sale un empalme hacia el siguiente control. Se debe de repetir la operación como tantos controles se vayan a conectar juntos en el mismo puerto. El común 'morirá' en el último control de la serie.
* '''GND tierra sin cuadro eléctrico kiconex:''' la malla (el recubrimiento del cable apantallado) irá conectada a la tierra de la instalación. Entre los controles conectados en serie, la malla ha de ir empalmada entre sí. Ésta 'morirá' en el último control.
* '''GND tierra con cuadro eléctrico kiconex:''' del bornero GND se conecta la malla del cable apantallado. El otro extremo se deberá de conectar con la malla del cable apantallado del siguiente control conectado en serie. La malla 'morirá' en el último control.

Wiring requirements

Use a halogen-free 3-wire shielded cable that provides protection against interference in Modbus RTU communication.
Distance of at least 20cm from power lines.
Respect the polarity of each RS485 connection
Connection between devices following a daisy-chain topology, as shown in the following image:

Common: if there is a connection for a common cable, a cable will come out of the terminal block (or kibox) that will go from the common to the common of the first control. It is connected to the common and from there a splice comes out to the next control. The operation must be repeated as many controls are going to be connected together in the same port. The common will 'die' at the last control in the series.
+ positive: A cable will come out of the terminal block (or kibox, depending on whether there is a kiconex electrical panel) that will go from the positive to the positive of the first control. It is connected to the positive and from there a splice goes out to the next control. The operation must be repeated as many controls are going to be connected together in the same port. The common will 'die' at the last control in the series.
- negative: A cable will come out of the terminal block (or kibox, depending on whether there is a kiconex electrical panel) that will go from the negative to the negative of the first control. It is connected to the negative and from there a splice goes out to the next control. The operation must be repeated as many controls are going to be connected together in the same port. The common will 'die' at the last control in the series.
GND ground without kiconex electrical panel: the mesh (the covering of the shielded cable) will be connected to the ground of the installation. Between the controls connected in series, the shield must be connected to each other. It will 'die' in the last control.
GND ground with kiconex electrical panel: from the GND terminal block the shield of the shielded cable is connected. The other end must be connected to the shield of the shielded cable of the next control connected in series. The shield will 'die' in the last control.

-Every control that connects to a Modbus RTU network with an RS485 connector has a series of characteristics or configurations that allow it to communicate through said protocol:
