Description
PROFIenergy is a PROFINET-based data interface for
switching off consumers centrally and with full coordi-
nation during pause times regardless of the manufac-
turer or device type. Through this, the process should
only be provided with the energy that is absolutely
required. The majority of the energy is saved by the
process; the PROFINET device itself only contributes a
few watts of savings potential.
S7-1500 CPUs support the controlled positioning and
traveling of axes via S7-1500 Motion Control functions
by means of the following technology objects:
Speed-controlled axes, positioning axes, synchronized
axes, external encoders, cams, cam tracks and meas-
uring inputs.
Speed-controlled axis for controlling a drive with
•
speed specification
Positioning axis for position-controlled positioning of
•
a drive
Synchronous axis to interconnect with a master
•
value. The axis is synchronized to the master axis
position.
External encoder for detecting the actual position of
•
an encoder and its use as a master value for syn-
chronous operation
Cams, cam track for position-dependent generation
•
of switching signals
Measuring input for fast, accurate and event-
•
dependent sensing of actual positions
PID Compact (continuous PID controller)
•
PID 3Step (step controller for integrating actuators)
•
PID Temp (temperature controller for heating and
•
cooling with two separate actuators)
