Get_Measurement_List
Command for providing a list of supported PROFIenergy measured
values.
0x02
Get_Measurement_Values
Command for providing the supported PROFIenergy measured val‐
ues.
Result
After receiving the command, the 3RW5 soft starter sends the requested information or an error
message.
Measured values
The measured values are uniquely identified by IDs. Dependent on the 3RW5 soft starter, the
following measured values are supported:

Accuracy of the specifications
The current values are transferred with the following tolerances:
• Accuracy Domain (unsigned8) = 0x03 → according to IEC 61557‑12
• Accuracy Class (unsigned8) = 0x11 → 5%
• Range (Float32) = I
e_max
(fixed value parameter)
It follows that the measured values are transferred with an accuracy of 5% relative to the
maximum configurable rated operational current I
