3.7 Functions
"Measured value function" command
Measured values for energy need to be supplied for efficient energy management.
The PROFIenergy specification offers various measured values from which to choose, each
of which is assigned a measured value ID. The SIMATIC ET 200SP motor starter supports
the instantaneous values of the phase current and the mean value of the phase currents as
measured values.
The measured values are uniquely identified by IDs. The following measured value IDs 7, 8,
9, and 33 are supported:
● ID = 7: Current rms value of the phase current a (L1)
● ID = 8: Current rms value of the phase current b (L2)
● ID = 9: Current rms value of the phase current c (L3)
● ID = 33: Mean value of the three phase currents (a+b+c)/3
The current values are transferred with the following tolerances:
● Domain = 0x03 → IEC 61557-12
● Class = 0x0B → 5 %
The result is that the measured values are transferred with an accuracy of 5 % relative to the
maximum configurable rated operational current I
Reaction of the starter when energy-saving mode is activated
Shutdown of the motor by suppression of the PIQ bits (Motor CW, Motor CCW). The other
PIQ bits (e.g. Trip RESET) remain active.
Interactions with the various operating modes
● PROFIenergy is operative only in Automatic mode
● Manual local mode is not influenced by PROFIenergy; → it is still possible to switch to
manual mode and thereby to control the motor manually.
● Both cyclic and acyclic data transmission (PIQ, PII, data sets, diagnostics, alarms, etc.) to
and from the motor starter are still possible.
Prerequisites for the starter to switch to energy-saving mode (min. idle time, etc.)
The changeover to "Pause" energy-saving mode only becomes effective when the idle time
sent is greater than the device-specific minimum idle time. This means that a switch is only
performed when the pause is longer than the motor starter requires to switch off and again
switch on the main energy for the load.
The switch to energy-saving mode is recorded in the "Events" logbook.
