In this project we describe a model to control an asynchronous motor using a frequency inverter in one of our PLCs based on Arduino.

It has been used an MDuino 42 I / Os PLUS and a frequency inverter.

An Industrial Shields Panel PC has also been used to manually monitor and control the speed of the conveyor belt and make it more intuitive.

Nuestro cliente estaba buscando una solución Open Source para implementar la automatización de su invernadero, de esta forma podría elegir qué protocolos de comunicación usaría, así como los lenguajes de programación o el uso de software Open Source entre otros motivos.

Greenhouse Monitoring and Control using Open Mote

This project is designed to measure the current consumption in a company using a current sensor. Through a database in the Ethernet PLC itself, it is possible to know the consumption statistics for medium and long-term tracing and even stop the current in case they exceed the allowed limit.

SUMMARY of the post:
What is Arduino Serial Communication and How to use it.
There are different types of Serial Communications. When you use an Arduino board in a project, you can choose the standard Serial pins such as Rx, Tx, from the UART inside the Arduino board, so it is called Serial TTL. In that case, you will use the Hardwareserial.h library but there are some additional pins that can work as an Rx or Tx. For example, the SPI communication pins can work as a MISO, MOSI and Select (SC), but they are also pins that can work as a digital input or digital output, or if you need you can use those pins as Rx, Tx using the library softwareserial.h.

Serial communications allow you to connect two different devices sending and receiving data between them.

The Serial TTL port can be transformed as required in the Industry as a RS232 and as a RS485. When RS232 is used, the functionality is quite similar to working as Serial TTL but, if you work with RS485, you can configure a network using a Master device that is capable of connecting to Slave devices. So the number of devices has been increased from 2 to 32 devices (nodes). And the maximum distance between them can be up to 1220m if the wiring is well done and EMC compliant and electrical noise is avoided.

To sum up, if you are using the UART serial port from the Arduino or from the Arduino based PLC for Industrial projects, the use of other pins working as a Serial TTL can help you with the successful development of your project. So, that additional serial port must be programmed using softwareserial.h library.

If the hardwareserial library can not be used because you need to use a communication protocol that requires the use of a physical UART instead of a virtual serial port, then, you could convert the RS232 or RS485 standard from the device to a Serial TTL. (This example will be shown in another post).

In this post, we explain the advantage of the SoftwareSerial library to simulate a serial port through Software (virtual serial TTL) using the Arduino IDE.

RESUMEN DEL POST:
Qué es la comunicación Serial con Arduino y cómo se utiliza la librería en el Arduino IDE

Hay diferentes tipos de comunicación Serial. Cuando se utiliza una placa Arduino en un proyecto, puedes utilizar el estándar de comunicación Serial desde los pins Rx, Tx, de la UART incorporado en la misma placa Arduino, lo que se llama SerialTTL. En este caso, utilizarás la librería Hardwareserial.h, pero hay otros pines adicionales que también te permiten trabajar como Rx o Tx. Por ejemplo, los pines de la comunicación SPI como son MISO, MOSI y Select (SC); de hecho, estos pines también pueden trabajar como entradas y salidas digitales, y tal y como explicamos son muy prácticos para utilizarse como Rx, Tx utilizando la librería softwareserial.h.

Las comunicaciones Serial te permiten conectar dos dispositivos diferentes enviando y recibiendo datos entre ellos.

El puerto Serial TTL se puede transformar a un estándar Industrial como son RS232 y RS485. Al utilizar RS232, la funcionalidad es bastante similar a la del puerto Serial TTL, aunque trabajas a un rango de voltaje estandarizado (ya que, para una placa Arduino Uno, Mega o Leonardo, el Serial TTL funciona a 5V). En cambio, si utilizas el puerto RS485, puedes configurar una red de comunicaciones entre dispositivos donde defines un equipo que trabaje como MAESTRO (Master), conectado a varios dispositivos configurados como ESCLAVOS (Slave). En este caso, el número de dispositivos que puedes conectar es de entre 2 a 32 dispositivos (comúnmente llamados Nodos). La máxima distancia entre estos dispositivos será de hasta 1220m, siempre y cuando el cableado esté bien echo y cumpliendo con los requisitos EMC, y el ruido eléctrico haya sido minimizado.
