Application and Installation

The Siemens 6AV1142-0DB10 text display mounts into a standard 138 mm x 68 mm panel cutout. It requires a 4-core cable for connection to the CPU. This display shows numeric values from timers, counters, and data words. Consequently, you can monitor key production metrics without a programming device.

Programming and Operation

This display uses simple text editors for message configuration. The Siemens 6AV1142-0DB10 stores messages in non-volatile EEPROM memory. Therefore, your text remains safe even during long power outages. Operators can acknowledge alarms using the built-in function keys.

Always power down the CPU before connecting or disconnecting this display. Match the interface cable wiring to the pinout diagram carefully. The unit features a removable terminal block for power wiring. Furthermore, its membrane keypad resists dust and light splashes.
