parameters.
5.1 PPO- description
The structure of the user data is designated as parameter process data objects (PPO) in the Profidrive profile.
The profile defines five PPO types, where SJ-PB supports all these PPO types.
There are PPO’s with a parameter area (PKW) and a process data area (PZD). There is also PPO’s that consist
exclusively of process data (PZD).
1. PPO1 consists of the PKW area and 2 words PZD.
2. PPO2 consists of the PKW area and 6 words PZD.
3. PPO3 consists only of 2 words PZD.
4. PPO4 consists only of 6 words PZD.
5. PPO5 consists of the PKW area and 10 words PZD.
The user can configure what shall be transferred in PZD3-10 (shaded grey below), for more instructions of how to
do this configuration see chapter 5.3.3, 5.4.2, 5.4.3 and Appendix.
