14.2 PPO Types
SI-PROFIBUS supports all five types of Parameter Process data Object (PPO) defined
by the PROFIdrive profile V4. The PROFIdrive profile features four specific functions
which the SI-PROFIBUS translates into appropriate drive functions:
• PROFIdrive control word
• Main Setpoint
• PROFIdrive status word
• Main Actual Value
Each PPO mode uses a unique combination of features which are detailed in the
following sections.
14.2.1 PPO 1
Table 14.3 PPO 1 mapping structure
14.2.2 PPO 2
Table 14.4 PPO 2 mapping structure
Do not confuse PPO 4 mode with Mode 2 - PPO 4 word non-cyclic data, they are not the
same.
