Transmitted Data, P74.70 to P74.89
To put data into the transmit PPO, it must be taken from
somewhere within the drive. Parameters P74.70 to P74.89 allow
the relevant PPO word to be allocated. See Table 7-3.

The PROFIDRIVE standard specifies that PZD1 (ZSW) contain a
status word following the definition in Table 7-4. The
Programmable Status Word in P41.32 or P41.33 is a collection of
status bits specified by parameters P41.00 to P41.15, or P41.16 to
P41.31. These can be used to set up the status word required by
PROFIDRIVE, and then point P74.30 to P41.32 or P41.33.
