8 Parameter Process Data Object Formats

8 Parameter Process Data Object Formats
◆
Supported Parameter Process Data Object (PPO) Type Formats
Set drive parameter F6-32 = "0" to use PPO type formats. The PPO is defined for cyclic data transfer, allowing the master and the slave to exchange
process data (PZD) and parameters. Refer to the PROFIBUS specification for more information on PPO types 1~5.
SI-P3 supports five possible PPO type formats:
PPO type 1 (8 octets PKW + 4 octets PZD)
PPO type 2 (8 octets PKW + 12 octets PZD)
PPO type 3 (4 octets PZD)
PPO type 4 (12 octets PZD)
PPO type 5 (8 octets PKW + 20 octets PZD)
All PPO Types have the registers STW, ZSW, HSW, and HIW. These registers are not mapped directly to drive registers.
