Modules like 9147 and 9120 are not affected by this change, since these
modules only have axis numbers as transfer parameters, and do not return any
information about spindles.
Also, some PLC words are affected by the conversion to the expanded PLC
module interface. For the PLC words concerned (e.g. W1024), the expansion
to 32 bits makes a conversion to double words (e.g. W1100) necessary so that
all pieces of information can be included. The previous words continue to be
valid, but they do not contain all of the 32 bits. The previous words will
therefore be copied to a double word with 32 bits.
