Energy Measurement

4.1.33
The device provides counters in the Modbus registers to acquire the following data:
•
Active import energy
•
Active export energy
•
Reactive import energy
•
Reactive export energy
The values are kept when the device is powered off or in sleep mode. The counter starts incrementing from
the last stored value once the device is powered on.
For more information about these counters, refer to
The counter value can be reset by any one of the following methods:
•
Using the Energy counter reset parameter via HMI
•
Using the Energy counter reset Modbus register. For more information, refer to

RTC Synchronization

4.1.34
The device provides an internal real-time clock. In order to get an external time synchronization, the device
must be synchronized with the Modbus master with the current system time. The real-time clock must be
synchronized at least once a day for a valid time stamp.
The device needs a time synchronization, when it resumes from the sleep mode to ensure the correct time and
date. Also the time synchronization is required when the device is powered on after 8 hours of sleep mode.
