11.13.1.1 Memory distribution
From software version V5.0 there are three different storage modes for the distribution of the cam
data memory in the controller. The specification of the storage mode is effected automatically by
the »Engineer« when the cam data file is generated.

Note!
For controllers with a software version lower than V5.0 the memory distribution always
corresponds to storage mode 1 (see following table), i. e. the max. size of the cam data
file is limited to 256 kBytes.
Storage modes 2 and 3 automatically provide a greater memory for an extensive amount
of cam data, however, in return certain functions are no longer supported (e. g. changing
cam data via parameterisation).
