Internal Architecture and Display Design

This operator panel uses an 8-bit processor for screen management and key scanning. A 4.5-inch monochrome LCD shows four lines of text with twenty characters each. The Siemens 6AV3515-1MA32 includes 28 membrane keys for navigation and data entry. Flash memory stores your HMI configuration without needing battery backup. A separate lithium cell maintains the real-time clock during power loss. This cell lasts approximately four years under normal operating conditions.

Installation and Connection Guide

First, cut a 172 mm x 130 mm opening in your cabinet door for mounting. Next, insert the panel from the front and secure it with the included brackets. Then, connect a 24 V DC power supply to the rear terminal block. Link the RS232 port to your PLC or programming PC for configuration. Use ProTool or OP15 configuration software to create your operator screens. The panel communicates with SIMATIC S5, S7, and third-party PLCs via RS422/485. Replace the lithium cell when the low battery warning appears on the display.
