Non Volatile Random Access Memory (NVRAM) block
Parameterizable special module (PSM) arithmetic, NVRAM block, function, general
If the input is activated (enabled) (EN) > 0, then following the activation delay, the value (W) of the coded signal is adopted for the result (E) (level operated).
If the input is activated (enabled) (EN) = 0, then the most recent value (W) of the result (E) is saved.
The result (E) is stored in the NVRAM (N) at switch-off.
When restarted, the result (E) is initialized with the value (W) stored in the NVRAM (N).
| Designation in data entry table | Data entry bit width | Meaning |
|---|---|---|
| AU_Memory_1_Delay | 16 bit | Activation delay (increment 20 ms) |
| AU_Memory_1_1 | 16 bit | Identification number (ID) of signal to be saved |
| Designation in signal ID list | Data bit width | Meaning |
|---|---|---|
| Out_AU_Memory_1 | 32 bit | Result (E) |
The same applies for other memory blocks with the naming convention:
- "AU_Memory_<Block number>_<Parameter designation>"
- "Out_AU_Memory_<Block number>"
