Simulating Motion Control

Restrictions
PLCSIM Advanced supports STEP 7 projects with configurations and functions for motion
control for the CPUs S7-1500 (F), S7-1500C, S7-1500T (F) und ET 200SP (F).
PLCSIM Advanced provides only limited support for technology objects in some CPUs, see
Restrictions with Motion Control (Page 352).
Simulation with external simulation software
Note
In a virtual S7-1500 controller, the technology objects are connected to the process image.
Simulation software can thus access the process image via the user interfaces (API) of
PLCSIM Advanced and simulate the behavior of the other connected axes.
Simulation mode in STEP 7
The simulation mode in STEP 7 is a standard function of the technology objects and is
independent of PLCSIM Advanced.
If you want to move an axis in simulation mode, select the "Activate simulation" check box in
STEP 7 under "Technology Object > Configuration> Basic Parameters > Simulation". No
additional setting is required for a virtual axis.
Feedback of the axis position
The speed setpoint of the simulated drive is integrated into the actual position value with a
time delay (PT1). The result of this calculation is returned to the technology object as
position actual value of the axis.
Reference point approach of the axis
If you selected "Use zero mark via PROFIdrive frame" in STEP 7 for the reference point
approach, PLCSIM Advanced responds immediately to any active (mode 2, 3, 8) or passive
(mode 4, 5) reference point approach command (MC_Home). The actual position is
predefined as the reference point.
Additional information
Information on "Setting in the drive and encoder connection" for actual value calculation of a
virtual axis and on the topic "Virtual axis/Simulation" is available in the S7-1500T Motion
Control (https://support.industry.siemens.com/cs/ww/en/view/109481326) function manual.
