HMI-Powered Automation for Food Waste and Compaction Systems

In industries such as automatic food processing and garbage compaction, the ability to manage complex sequences, monitor real-time status, and simplify control architecture is critical. By integrating HMI technology with advanced control capabilities, operators can achieve unified, efficient automation without the need for separate PLC hardware. This case showcases how Weintek’s HMI system is transforming compact equipment automation through powerful, space-saving design.

Challenges on Food Waste Processing

A Washington-based manufacturer specializing in food waste and material compaction systems, several challenges emerged:

  • Need for Real-Time Control: Coordinating dumper and auger movement required precise motor control and feedback.
  • Redundant Hardware: Traditional PLC + HMI setups increased complexity, size, and cost.
  • Limited Connectivity: Equipment needed to be remotely accessible for monitoring and support.

Weintek’s Solution

Weintek provided a compact yet powerful solution built around the cMT3090 HMI with CODESYS soft PLC and the iR Series remote I/O modules.

Core Technology and Device Setup:

  • cMT3090 HMI:
    • 9.7" touch panel, Cortex-A9 processor, 1GB RAM
    • Runs both HMI & PLC projects via CODESYS, eliminating external PLC
    • Built-in EasyAccess 2.0 for encrypted remote access
  • CODESYS Soft PLC Integration:
    • Enables real-time control logic directly within the HMI
    • Supports manual and automated sequences
  • Remote I/O Modules:
    • IR-ETN: Ethernet coupler between CODESYS and I/O
    • IR-AM06: Analog module for current feedback, speed control
    • IR-DI16K: Digital input module for gate sensors, emergency stop
    • IR-DQ08: Digital output module for motor direction control

Through this configuration, the entire system’s visualization, control, alarms, and historical data were centralized in a single HMI device.

Outcomes and Benefits

  • Reduced Hardware Footprint: One device manages both PLC logic and HMI interface.
  • Improved Responsiveness: Real-time data from sensors and drives informs precise control.
  • Remote Access & Monitoring: EasyAccess 2.0 ensures secure, global system visibility.
  • Simplified User Interface: A clean touch interface integrates system dashboards, motor controls, alarms, and setup in one place.
