As industrial automation systems become more sophisticated, machine designers and OEMs face increasing pressure to reduce panel space, simplify wiring, lower costs, and accelerate development cycles. One solution that continues to gain popularity across manufacturing and machine-building industries is the HMI/PLC Combo, an integrated device that combines a Human Machine Interface (HMI) and Programmable Logic Controller (PLC) into a single compact unit.

Anaheim Automation proudly partners with Kinco Automation to offer these HMI/PLC Combo units designed to deliver powerful machine control and intuitive operator interaction while simultaneously reducing the complexity of traditional control architectures.

Available in both 4.3" and 7" touchscreen configurations, these integrated systems provide a cost-effective and space-saving alternative to separate PLC and HMI installations, making them ideal for OEM equipment, packaging machinery, material handling systems, process automation equipment, and countless other industrial applications.

Traditionally, automation systems utilize separate PLCs and HMIs connected through serial or Ethernet communications. The PLC executes machine logic while the HMI provides visualization, monitoring, and operator control.

An HMI/PLC combo integrates both functions into a single device:

• PLC processing and I/O management
• Operator interface and visualization
• Communications functionality
• Vivid touchscreen display
• Reduced hardware requirements

By combining these functions into one platform, machine builders can simplify system design while maintaining reliable control performance.

One of the most significant advantages of an HMI/PLC Combo is the dramatic reduction in wiring requirements. With separate devices, engineers must install:

• PLC power wiring
• HMI power wiring
• Communication cables between devices
• Additional mounting hardware

By integrating both systems into a single unit, communication between HMI and PLC occurs internally, eliminating many potential wiring and communication issues.

Benefits Include:

• Faster installation
• Simplified troubleshooting
• Reduced labor costs
• Cleaner control panel layouts
• Fewer connection points that can fail

Control cabinet real estate is often at a premium. Replacing a standalone PLC, HMI, communication hardware, and associated wiring with a single integrated device can significantly reduce required panel space.

This is especially valuable for:

• Compact machinery
• Mobile equipment
• Skid-mounted systems
• Distributed automation systems
• Retrofit projects

Smaller cabinets often translate into lower material costs and improved thermal management.

Integrated HMI/PLC platforms simplify system architecture, enabling engineers to:

• Reduce component selection time
• Minimize integration challenges
• Accelerate commissioning
• Simplify documentation

For OEMs producing multiple machine variants, this can help reduce engineering hours and shorten time-to-market.

Combining multiple automation functions into a single unit often reduces:

• Hardware costs
• Installation costs
• Wiring expenses
• Inventory requirements
• Spare parts management

The result is a more economical automation solution without sacrificing functionality.

Like any engineering solution, HMI/PLC Combo units involve certain tradeoffs.

With separate PLC and HMI devices, either component can be upgraded independently. An integrated unit combines both functions into one package, meaning upgrades typically involve replacing the entire device. The positive side? For many OEM applications, machine designs remain stable for years. The simplified architecture, lower component count, and reduced maintenance requirements often outweigh the benefits of independent upgrades.

Extremely large automation systems with hundreds of I/O points or extensive networking requirements may still benefit from dedicated PLC platforms. However, the majority of machine automation applications fall within the ideal performance range of integrated HMI/PLC solutions, making them an excellent choice for OEM equipment and standalone machinery.

Anaheim automation offers three powerful integrated HMI/PLC solutions designed for a wide range of automation applications.

Kinco HMI/PLC Combo units are versatile solutions that can be deployed across numerous industries.
