Controlling and Monitoring the SVX Drive with
the Siemens PLC
In place of a user program, this example will add the I/O
tags for the SVX Drive to the Tag database, then to a Watch
List and control the device by modifying the Output tags
and monitoring the input data.
Adding I/O tags
Under the Project tree, open “PLC tags” and select “Show
all tags” and the following will be displayed:
Figure 46.
Add the I/O tags and their I/O address as assigned by the
PLC, per the following:
Figure 47.
Next, double click “Add new watch table” under “Watch
and Force tables” in the Project Tree on the left per the
following:
Figure 48.
The new watch table is named “SVX” for this example.
Add the I/O addresses for the SWD devices as shown
below. Note that the addresses for these tag names that
you entered into the PLC Tags area are automatically
populated as the tag names are selected. This watch table
will allow testing the SVX drive over PROFINET without
writing a program. This will allow monitoring the input data
from the SVX drive, while also operating it.

Downloading the program to the Siemens S7 PLC
The project must first be compiled with no errors before it
is downloaded to the PLC. In the Project Tree under PLC_1
[CPU….], double click “Device configuration” as follows to

Select the PLC then click the Compile button. The compile
button is just to the left of the Download button on the tool
bar. Shown below are, from left to right: Compile button,
download button and the upload button. As you hover
over each of these buttons in the software, it will display
its function.
