Text and Graphics Display Capability

The MI4-110-KG2 features a monochrome LCD display with 4 lines of 20 characters, providing clear alphanumeric text for machine status messages, production data, operator prompts, and parameter values. The display also supports pixel graphics, enabling basic graphical elements such as bar graphs, trend lines, and simple machine representations. This graphic capability allows operators to visualize process variables such as fill levels, pressure trends, or temperature profiles without requiring a full graphics panel. The display is backlit for visibility in varying lighting conditions, ensuring readability in both bright and dim factory environments.

Programmable Function Keys

Twelve programmable function keys provide direct access to machine control functions, allowing operators to start, stop, reset, or adjust machine parameters with a single key press. These keys can be configured in the HMI project to perform specific actions, navigate through screens, or enter values based on the current context. The function keys reduce the need for menu navigation, enabling efficient operation and faster response times during production changeovers or fault recovery. The tactile feel of the keys provides positive feedback for operator confidence.

Sucom A Communication Interface

The MI4-110-KG2 uses Sucom A communication protocol, a standard interface for Moeller automation products. This serial protocol enables connection to Moeller PS4 and PS416 programmable controllers, as well as other Moeller automation devices. The Sucom A interface provides reliable data exchange between the HMI panel and the PLC, allowing the panel to read and write PLC memory areas, display process values, and send commands to the controller. The communication parameters are configurable to match the connected PLC configuration.

Integration with Moeller PLC Systems

The MI4-110-KG2 is specifically designed for integration with Moeller automation systems. In the field of automation, PS4 and PS416 programmable controllers and MI4/MV4 machine interfaces complement each other to provide a powerful team for machine control and management. The panel can display values from PLC memory, monitor I/O status, and send operator commands back to the controller. The combination of Moeller PLCs and MI4 operator panels provides a complete control solution for machine building and process automation applications.

Printer Connection and Data Logging

The MI4-110-KG2 includes a printer output interface, enabling connection to an external printer for hard-copy documentation of production data, alarm logs, or process reports. This feature is valuable for applications requiring paper records for quality assurance, regulatory compliance, or shift reports. The printer output can be programmed to produce custom report formats, with data sourced from the connected PLC or entered by the operator through the panel's function keys. The ability to print documentation directly from the HMI reduces the need for separate data logging systems.

Panel Mounting and Industrial Design

The MI4-110-KG2 is designed for flush mounting in control cabinet doors or operator stations. The panel mount design provides a clean, professional appearance on machinery and control panels, with the display and function keys accessible from the front. The enclosure is constructed from industrial-grade materials suitable for factory environments, with proper sealing around the display and mounting points. The panel's dimensions occupy minimal panel space while providing adequate area for display and keys.

Programming and Configuration

The MI4-110-KG2 is programmed using MI4-CFG-1 configuration software, compatible with Windows 98, ME, NT, 2000, and XP operating systems. The software provides tools for creating screen layouts, defining function key actions, establishing communication parameters, and configuring alarm messages. Projects can be developed offline and downloaded to the panel via a serial connection using the ZB4-24A-KP1 configuration cable (RS232, 9-pin serial PC connection). The software supports text and graphic elements, allowing designers to create clear and intuitive operator interfaces.

Industrial Applications

The Moeller UNIOP MI4-110-KG2 operator panel is deployed across a wide range of industrial automation applications. In machine control, it provides operator interface for packaging equipment, assembly systems, and material handling machinery, displaying production counts and allowing operators to start, stop, or reset the equipment. In process control, it monitors temperatures, pressures, and flow rates, with graphical displays of process variables over time. In building automation, it controls and monitors HVAC equipment, lighting systems, and access control. The panel's 4x20 text display and 12 function keys provide sufficient capability for applications requiring operator interaction without complex graphic displays.

Application Notes

The MI4-110-KG2 unit does not include battery backup, as noted in the MI4 hardware documentation. This means that time-of-day clock and data memory may be lost during power interruptions unless the panel remains powered from an external source, or unless the application does not require persistent clock functions. For applications requiring real-time clock persistence, other MI4 models with battery backup should be considered. All MI4 panels require proper grounding and electrical isolation as specified in the engineering guide.

Conclusion

The Moeller UNIOP MI4-110-KG2 text/graphics HMI panel provides operator interface for Moeller PLC systems with 4x20 display, 12 function keys, Sucom A communication interface, and printer output. Its compact design, programmable keys, and industrial construction make it a practical solution for machine control applications requiring basic operator interface with text and graphics capability.
