|---|---|
| Memory Type | Flash (non-volatile) |
| Storage Capacity | 4 MB |
| Compatible Panels | SIMATIC OP, TP, MP series |
| Write Protection | Mechanical slider switch |
| Data Retention | 10 years minimum |
Energy Storage and Power Requirements
The Siemens 6AV3971-1CA03-0CA0 draws 45 mA during read operations. It requires 70 mA when writing data to flash memory. The card contains no internal battery or supercapacitor. Therefore, it retains all data without any external power source indefinitely.
Installation and Data Transfer Performance
Users can copy projects from a PC using a standard PCMCIA adapter. The card transfers data at up to 1.5 MB per second. A status LED on the HMI indicates active read or write operations. This feature prevents card removal during critical data transfers.
