3.10 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!
