Here is example on energy meter EM133
1. Send password
1.1. When password up to 4 digits you can send it to register 2575.
1.2. When password up to 8 digits you can sent it to register 44378 and 44379. We recommend to choose this option anyway.
2. Sending date/time into device. Must be sent all 6 fields.
* send writing (updating) requests shortly after sending password. If communication session will be closed should send password again before sending writing requests.
3. Verify time of RTC or/and find appropriate record in Event log of the device.
To reset other data in SATEC devices refer registers Device Reset/Clear Registers on page 47.
Before sending any updating should be send correct password. Else SATEC device will response a NAK error (no acknowledge).
Then the device allows updating till communication session is open.
4. Deleting Historical data : Event/data logs.
This example is based on energy meter EM920.
Send value 127 to register 63120 and number of Event/Data log to register 63121.
