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…

RTC library for Arduino based PLC (DS1307 RTC)

RTC library for Arduino based PLC (DS1307 RTC)

The Industrial Shields PLCs use original Arduino boards. Then the PLCs can be used as individually Arduino boards by The Arduino IDE. To use the original boards let the users to programm the PLCs by others programs which can program Arduino boards too.  The Ethernet family PLCs (M-Duino) use an original Arduino Mega. The 20IOs PLC (Ardbox) use an original Arduino Leonardo. You can use different models of RTC with the PLCs. This example shows how tu use the DS1307 RTC board….
