HVAC System activated through an SCADA

HVAC System activated through an SCADA

Introducción Como continuación del post sobre control de un Aire acondicionado, hoy proponemos expandir el sistema de control del aire acondicionado a través de un Panel PC basado en Touchberry Pi y un Ardbox Relay de IndustrialShields. Recuerda del último post que el SCADA usado para correr sobre la Touchberry se puede encontrar aquí.  A modo de recordatorio y resumiendo, en el post anterior diseñamos un sistema que era capaz de activar el aire acondicionado a través de un relay. Ahora para poder…

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Introducción En la industria, la necesidad de controlar la temperatura es habitual. Un elemento típico utilizado y diseñado con este propósito es el intercambiador de calor, que intercambia dos o más fluidos con diferente temperatura.En este post vamos a explicar cómo implementar un control de la temperatura a través de una válvula de modulación que va a regular la cantidad de vapor que entra en el intercambiador de calor, con el fin de calentar el proceso químico. Para cumplir con…

Feeding a packaging machine with a frequency driver with Arduino

Feeding a packaging machine with a frequency driver with Arduino

En la industria lechera, las máquinas de envasado se utilizan para envasar los alimentos en recipientes tales como yogur, leche, etc. Por lo general se integran en sistemas más complejos, y están alimentados por un tanque que contiene el producto (por lo general la leche). En este proyecto vamos a diseñar un sistema compuesto de un tanque con leche, una máquina de envasado, una válvula para abrir y cerrar el camino a la máquina, y un PID formado por un…

Tools40 library, useful tool using our equipments

Tools40 library, useful tool using our equipments

This is Industrial Shields library for our different PLC’s  Tools40 library include SimpleComm library, Filter library and Timer library. With the SimpleComm library you can send data through any Arduino Stream: RS-485, RS-232, and Ethernet… It is enough flexible to support different kind of communication typologies: Ad-hoc, Master-Slave, Client-Server… Using an easy to use API. Filter library includes filtering software that allow you to smooth analog inputs. This is really useful when you have an analog signal that is unstable. With Timer library you can create…

How to touch up data from the EEPROM

How to touch up data from the EEPROM

EEPROM is a memory whose values are kept when the board is turned off. In this example it is showed how to write and read from the EEPROM. In our products, Ardbox  has 1KB and M-Duino  has 4KB of EEPROM This example we will see how to use functions EEPROM.write(), EEPROM.read(),EEPROM.put() and EEPROM.get().

How to connect and configure a load cell using HX711 transmitter with Arduino based PLC

How to connect and configure a load cell using HX711 transmitter with Arduino based PLC

In this post is showed how to use a load cell transductor with our equipment’s for example an Ardbox analog. Load cell is a transductor that generate an electrical signal directly proportional to the measured force. On market there are different transmitters that can convert this analog signal to digital. In this example is used the HX711 that is very used in industrial applications. HX711 get and convert the analog signal from the load cell to digital with his intern converter…

How to generate a different PWM’s signals with Arduino based PLC

How to generate a different PWM’s signals with Arduino based PLC

On this example is explained how to generate a PWM with M-DUINO  and ARDBOX In our equipment’s you can generate a PWM on Digital/Analog Ports. But most of these ports have a limitation of frequency (500 Hz approx.). PIN3 for ARDBOX and PIN3 and PIN2 for M-DUINO don’t have limitation and they can generate a PWM between 100Hz (even less) and 8MHz. PIN3 for ARDBOX can work as an external output for the Timer/Counter0 Output Compare B (OC0B). And the…
