Functional Architecture and Message Retrieval

This text memory connects directly to the HDI operator panel. It stores pre-programmed text for alarms and status conditions. You can recall each message using a numeric index. Moreover, the module includes fast access circuitry for instant retrieval. This component delivers text within 1 microsecond of request. Consequently, the operator panel displays alarm messages without noticeable delay.

Installation and Operational Guidelines

The Siemens 6AV1142-1DA10 retains all text data for over 20 years. It requires a UV eraser and EPROM programmer for updates. You must align pin 1 with the socket marker carefully. Always cover the quartz window with an opaque label after programming. This practice prevents accidental erasure from ambient light. Furthermore, the module supports message chaining for multi-line displays. This feature combines several messages into one screen.

Physical Characteristics and Environmental Limits

This text memory module features a ceramic body with quartz window. Its moderate 0.48 kg weight reflects the industrial construction quality. The layout follows Siemens standard HDI module specifications. Therefore, it fits securely into any SIMATIC HDI operator panel. The module requires no battery backup for data retention. In addition, it maintains stable operation between 0°C and 55°C ambient temperature. You can store this unit safely between -20°C and 70°C.
