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/V supports five possible PPO type formats:
All PPO Types have the registers STW, ZSW, HSW, and HIW. These registers are not mapped directly to drive registers.
Configuration of Registers
PKE
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)
