Answer Question
Can you see in the PLC program if the drive controller
is switched on?
Yes, you can see this by means of a status word.

• A prerequisite for this kind of monitoring is the
additional use of the process data channel.
• In addition, the drive controllers should use an
external 24V supply.
Should the drive controllers use an external instead of
an internal 24V supply? Yes, absolutely, otherwise PROFIBUS will slow down if
devices are missing. In addition, this allows you to
detect easily in the PLC program if drive controllers are
switched on.
Why is the error message ”Can’t make directory...”
displayed in the DOS window when the “Ldslib.arj”
library or the “Ldsexmpl.arj” example project is
retrieved with the default STEP7 program “arj.exe”?
The DOS program “arj.exe” can only retrieve archives
up to a defined directory depth which might be
exceeded if STEP7 is not installed in the root directory
of the hard disk (e. g. “c:\...”) but in a sub-directory
(e. g. “c:\Programs\...”).
• Use the program “pkzip25.exe” part of the STEP7
delivery package and retrieve the ZIP archives
“Ldslib.zip”/“Ldsexmpl.zip” instead of retrieving
the ARJ archives “Ldslib.arj”/“Ldsexmpl.arj”.
• The program to be used for archiving is configured
in the SIMATIC Manager via OptionsWSettings.
