manualsaved (Index 0x90x0:01 and 0x90x0:02)
The energy values of channels 1-3 can be saved in the Objects 0x90x0:01 (e.g. before switching the system off in order to save the energy value as accurately as possible) or the energy values already saved can be deleted. This is initiated by the Command Object (Index 0xFB00:01). The negative energy value (generator mode) can be saved in the Objects 0x90x0:02. These values can only be saved or deleted manually.
This value is saved under Index 0xF801 in the case of the EL3403. For reasons of compatibility this index also exists in the EL34x3. If program modules are to access this index, these can continue to be used. However, it is recommended to use Index 0x90x0 in new applications.
autosaved (Index 0x90x0:03 and 0x90x0:04)
The energy values of channels 1-3 are automatically saved in the Objects 0x90x0:03 every 15 minutes. Beyond that the user has the possibility using the Command Object (Index 0xFB00:01) to also save the momentary energy value at a self-defined moment or to delete complete contents. The 15-minute timer starts again at zero at this moment.
Sample 1
If the energy value of all the channels is to be saved manually, enter 0034hex in index 0xFB00:01.
