IIOT enabled AC induction motor speed control training system using PLC and HMI

FEATURES

The PLC (Allen-Bradley/Siemens) system is equipped with 12 digital inputs, 8 digital outputs, 4 analog inputs, and 2 analog outputs, providing the necessary I/O capabilities for various industrial automation tasks. It also features Ethernet communication support, enabling seamless integration into industrial networks for remote monitoring, control, and diagnostics. The system comes with PLC programming software, allowing users to program the PLC using standard languages such as ladder logic or structured text. The system includes a 7-inch HMI with Ethernet communication and programming software. Real-world components like toggle switches, proximity sensors, selector switches, visual and audio indicators, DC motors, relays, contactors, AC drive, and induction motor offer students hands-on, practical experience with equipment they might encounter in the field. The system allows AC motor speed control process monitoring and control from anywhere using mobile devices and applications.

TECHNICAL SPECIFICATIONS

The system includes 8 toggle switches, 5 push-to-ON switches, 1 proximity sensor, 1 selector switch, 4 visual indicators, 1 audio indicator, 1 DC motor, 1 relay card containing 2 relays, 1 contactor, 1 AC induction motor with VFD, and 1 IIOT device.

EXPERIMENTS

Program operation of NO (normally open) and NC (normally closed) instructions, types of logic gates, set and reset bits, timers, counters, types of compare instructions (greater than, equal to, and less than), types of math instructions (addition, subtraction, multiplication, and division), analog input, and analog output instructions using MOV instruction. Writing a ladder program to control an AC induction motor using the PLC. Creating a GUI in HMI to display the status of NO and NC contacts and control them. Creating a GUI to monitor and control timers in HMI. Creating a GUI to monitor and control a counter connected to the HMI. Creating a GUI to display and monitor analog input data from a PLC. Creating a GUI that allows the operator to control an analog output signal to control devices. Controlling the speed of an induction motor using HMI. Understanding the working principle of the variable frequency drive (VFD), hardware connection, parameter setting, acceleration and deceleration time setting, jog mode operation, and direction control operation of the motor. Learning how to develop and utilize cloud-based SCADA systems for global access to process data and remote control. With cloud SCADA, users can access live process data, control operations, and monitor systems from anywhere using mobile devices and applications. Gaining experience in data logging, downloading data, and analyzing alarm histories through the cloud SCADA system. Users can export data directly into Excel to track process performance, monitor trends, and optimize operations.
