Siemens 6ES5391-5AA13 Operator Panel

Why This Operator Panel Provides Basic Machine Interface

This operator panel offers essential controls for SIMATIC S5 systems. You get a straightforward Siemens 6ES5391-5AA13 for simple machine operations. It features indicator lamps and selector switches on the front face. Therefore, operators can start and stop processes without a full HMI terminal.

Technical Specifications and Physical Details

The Siemens 6ES5391-5AA13 includes eight LED indicators and six selector switches. It connects directly to the S5 I/O bus through a ribbon cable. This panel mounts flush into a control cabinet door. Its dimensions measure approximately 216 mm in width and 108 mm in height. The unit weighs around 0.65 kg for secure installation. This operator panel stores no configuration data internally. Instead, the CPU controls all indicators and reads all switch positions. Consequently, you lose no settings during a power cycle or panel replacement.

Below is the detailed breakdown of the hardware specifications.

Installation and Connection Notes

This panel mounts into a standard 216mm x 108mm cutout. You must connect the ribbon cable to the correct I/O module. The Siemens 6ES5391-5AA13 requires a dedicated address in your PLC program. Therefore, assign input bits for the switches and output bits for the LEDs. Always secure the panel with all four corner screws. A loose panel will cause intermittent connection issues.
