92 Busserver S7 DE/EN 1.0

Example of a transfer parameter list:

CALL ”Lenze-DriveServer_FB”, DB100 FB90

Tag :=

PB_Address :=B#16#9

EA_Address :=1000

DriveServer_DB :=”Lenze-DriveServer_FB” DB80

DrivePar_DB :=”S7-Parameter” DB81

TimerNr :=T1

TimeOut :=

Busy :=MB100

Transfer parameters used in the above list:

• The parameter Tag must not be specified.

• In this example, the PROFIBUS address is address 9.

• I/O address 1000 was set as a device parameter in the Hardware Manager.

• T1 is to be used as timer.

• As the parameter Timeout was not specified, the factory setting (1s) is used.

• The flag byte MB100 is used to ascertain, if an instance is accessing an I/O.

Tip!

The PROFIBUS and the I/O addresses ha ve to be configured twice, once in the Hardware Manager and

once in the calling program. It is important that the two configurations correspond.

Providedthat a drive is available at PROFIBUS address 9, the system can be operated with thisprogram.

• Load the program into the PLC and try to detect the drive automatically using the S7

configuration tool.

(^ 76)

• Once the completed configura tion has been registered and saved with the S7 configuration tool,

the DriveServer can access all parameters of the drive.

Tip!

The PLC programs can be written in any S7 language, the function block FB DRIVE (FB90) is, however,

protected and cannot be processed in any of these languages.
