Siemens 6V3020-1EL00 Text Display

Compact Operator Interface for SIMATIC S5 Systems

The Siemens 6V3020-1EL00 provides a dedicated text display unit for the SIMATIC S5 programmable controller family. This display features a 4-line LCD screen with 20 characters per line for clear process data presentation. Its compact housing measures 144 mm in height, 72 mm in width, and 48 mm in depth, fitting standard control panel cutouts. The total weight reaches approximately 0.35 kg, making it one of the most lightweight operator interface options.

This text display supports both numeric and alphanumeric data presentation with adjustable contrast control. The following table details the complete technical specifications for this text display solution:

Display Performance and Visual Clarity

The 4-line by 20-character LCD presents process variables, alarms, and operator prompts with excellent legibility. Manual contrast adjustment lets users optimize visibility for different ambient lighting conditions. The character format includes both numeric digits and alphabetic characters for versatile data presentation. Operators can therefore monitor machine status and diagnostic messages without requiring a full graphic HMI.

Communication and System Integration

The 6V3020-1EL00 connects to S5 CPUs through an RS-232 interface using the 3964R communication protocol. This interface supports parameter setting, data display, and simple operator commands. The unit communicates with the PLC without requiring additional interface cards or converters. Engineers can therefore integrate this display quickly into existing S5 systems with minimal configuration effort.

Mounting and Environmental Suitability

The compact 144 mm x 72 mm panel cutout fits standard industrial operator stations. IP65 front-panel protection resists dust, water spray, and cleaning chemicals. The unit operates reliably from 0°C to +50°C, covering most indoor industrial environments. This display provides an economical text-based interface for basic operator control and monitoring needs.
