AnswerQuestion

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 da ta channel.

• In addition, the drive c ontrollers 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 director y...”

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-director y

(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 Options

WSettings.
