Mapping indexes to codes

The operating system as of V6.0 of the Lenze PLCs contains a specific CanDSx driver which can be
activated using the functions of the LenzeCanDSxDrv.lib function library.

(

^ 11−1)

By means of this driver indexes within the PLC can be assigned to another code as the one which
is automatically allocated.

Notes!

·

Each Lenze code is fixedly assigned to an index via the following formula:

Index = 5FFF

hex

− code

Index = 24575

dec

− code

·

The function of the CanDSx driver only is limited to the system bus (CAN).
– For the second FIF−CAN channel provided for the drive PLC, the CanDSx driver cannot be

used!
