Introduction 1
Introduction
This Getting Started contains a practical example guiding you through eleven steps in
commissioning a fully functional application, and showing you how to carry out motion
commands. It is thus a valuable help in getting started with the basic functions of a CPU
317T-2 DP.
Depending on your degree of experience, working through the sample will take between one
and two hours.
Note
This Getting Started presumes that you have connected a SIMODRIVE 611 universal drive
to the DP(DRIVE) interface of the CPU 317T-2 DP In case you do not have a drive, we
recommend you refer to the Getting started documentation "CPU 317T-2 DP: Controlling a
virtual axis
Note
You can also use the CPU 315T-2 DP instead of the CPU 317T-2 DP. To do this, select
CPU 315T-2 DP in HW Config. Otherwise, the configuring steps are the same.

Important information
In this step, you create your technology objects (e.g. axes) with S7T Config. Use
"Technology Objects Management" to generate a technology DB for each TO. Do not copy
the technology DBs in order to ensure a defined assignment between the technology DB and
its TO.

Programm > Technology entry.
Double-click "Technology objects“ to open S7T Config.
Result: "Technology Objects Management" opens. The system automatically runs S7T Config if you have
not configured any technology objects yet, as in this example.
You may also run S7T Config without using "Technology Objects Management". Select the "Technology
Objects" object and then select the Options > Configure technology menu command.
Result: "S7T Config" opens.
