Functional Description

The LP 056/02 provides a simple yet effective text-based operator interface. The 2x20 display can show a parameter label and its corresponding value, or a status message. The 4 function keys can be used for scrolling, acknowledging alarms, or triggering commands. The panel is ideal for applications such as conveyor control, pump monitoring, and simple machine control.

The panel communicates via Modbus RTU, making it compatible with most PLCs and automation controllers. It is often used as a local display for variable speed drives, temperature controllers, and flow meters.

Installation and Mounting

Install the unit in a standard 92 x 45 mm cut-out. Secure with the supplied spring clips. Connect the 24 V DC power and the RS-485 communication cables to the terminal block on the rear. The Modbus address is set via DIP switches on the back of the unit.

Configuration and Programming

Configuration is performed using the Lauer LP Editor. Users can define the screens to be displayed, assign Modbus registers to be read, and configure key functions. The configuration is downloaded via the RS-232 port.

Maintenance and Diagnostics

The LP 056/02 requires minimal maintenance. Routine cleaning of the display with a soft cloth is recommended. The unit includes a self-test function that runs at power-up.

Integration with Control Systems

As a Modbus RTU slave, this display can be integrated into any automation system with Modbus communication capability. It is widely used for local indication of process values and simple operator control.

Environmental and Safety Compliance

CE and RoHS compliant. Designed for industrial use in controlled environments.

Technical Support and Documentation

A user manual, configuration guide, and Modbus register map are provided. Technical support is available through Lauer distributors.

Conclusion

The BS Lauer LP 056/02 Operator Panel is a simple, cost-effective, and reliable solution for applications requiring basic text display and keypad functions in industrial automation.
