TIA Portal
The TIA Portal supports you in the planning and commissioning of Motion Control
functionality:
● Integrating and configuring hardware
● Creating and configuring technology objects
● Creating the user program
● Downloading to CPU
● Commissioning of axes
● Optimization of drives
● Diagnostics
You use the TIA Portal to configure the hardware, the technology objects as well as your
user program. You download the program you created to the CPU. You test your user
program and diagnose the hardware with the online and diagnostic functions of the
TIA Portal.
Technology objects
Technology objects represent real objects (e.g., a drive) in the controller. You can call the
functions of the technology objects by means of Motion Control instructions in your user
program. The technology objects provide open- and closed-loop control of the movement of
the real objects, and report status information (e.g. the current position).
The configuration of the technology objects represents the properties of the real object. The
configuration data are stored in a technology data block.
The following technology objects are available for Motion Control:

Speed axis technology object
The speed axis technology object ("TO_SpeedAxis") permits the specification of the
speed for a drive. You program the movement of the axis with Motion Control
instructions.
Positioning axis technology object
The positioning axis technology object ("TO_PositioningAxis") permits the position-
controlled positioning of a drive. You assign positioning jobs to the axis with Motion
Control instructions in your user program.
