PLC and HMI Control Baking System application training system

FEATURES

The PLC (Allen-Bradley/Siemens) system is equipped with 20 digital inputs, 12 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 licensed 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, a baking system, solenoid valve, and BO motor offer students hands-on, practical experience with equipment they might encounter in the field. The system helps in understanding the concept of a baking system.

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, a conveyor system, BO motor, solenoid valve, heater, and exhaust fan. The Human Machine Interface (HMI) features a 32-bit 400MHz RISC CPU with a 7-inch high-resolution TFT LCD display (800 × 480) offering 65,536 colors. It supports a +24V DC power supply, has 128MB flash storage, 64MB DDRAM, and a high-precision four-wire resistive touchscreen, and includes an Ethernet interface for connectivity.

EXPERIMENTS

Program operation of NO (normally open) and NC (normally closed) instructions, types of logic gates, set and reset bits, types of timers (TON, TOFF, and TONR), types of counters (CTU, CTD), 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.
