A common amphitheater classroom usually contains lights and air conditioners. We implemented an HMI device to control all of the lights and air conditioners in our ICP DAS Amphitheater Classroom at our headquarters. We also use several scenarios—such as Meeting, Proposal, and Class—to simplify amphitheater operations.
Every light and air conditioner should be controlled by a touch HMI device. An amphitheater classroom usually has many switches for all of the lights. Because of the large number of lights, it is not possible to place them all on one screen of the touch HMI device. To save space, we implemented multi-page control. We also used scenarios for easier control from the HMI device.
We used the following devices:
-1 × TPD-430 (16M SDRAM / 8M Flash touch HMI device)
-19 × M-7065D (4 digital inputs / 5 relay outputs module)
-1 × M-7018 (8 analog inputs module)
As shown in the application diagram, we used the TPD-430 to control the M-7065 and M-7018 Modbus RTU–based data acquisition modules. The M-7065 is used to control lights and air conditioners, while the M-7018 is used to read the temperature value of the sensor (thermocouple).
