Display Capabilities and Operator Controls

The monochrome LCD presents both text and simple graphics effectively. A built-in CCFL backlight ensures visibility in dim industrial lighting conditions. The Siemens 6AV3525-1TA41-0BX0 includes twenty-two tactile response membrane keys. Fourteen of these keys accept custom labeling for specific machine functions. A numeric keypad enables rapid data entry without screen navigation. The display contrast adjusts through a potentiometer accessible from the rear. You can store up to 80 screen pages in the internal flash memory.

Communication and System Integration

You connect this panel to a Siemens PLC using any available serial interface. The unit supports RS-232, RS-422, RS-485, and 20 mA TTY standards. A 9-pin D-sub connector provides the primary connection to the controller. The Siemens 6AV3525-1TA41-0BX0 also acts as a PROFIBUS DP slave device. It draws its operating power from an external 24V DC supply. The panel includes a replaceable lithium battery for real-time clock backup. This battery maintains the clock for approximately five years.

Installation and Environmental Guidelines

You must cut a mounting hole measuring 140 mm by 196 mm in the cabinet door. The panel seals against the door using an included foam rubber gasket. The front face carries an IP65 rating for dust and water protection. Consequently, you can clean the panel with a damp cloth safely. The operating temperature ranges from 0°C to 45°C for reliable performance. You should avoid exposing the panel to direct sunlight for extended periods. The CCFL backlight has an average lifespan of 50,000 operating hours.
