◆
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. Refer to the
PROFIBUS specification for more information on PPO types 1~5.
PROFIBUS-DP Option 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.
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)
PPO TYPE 5: Octet-String 28
PPO TYPE 4: Octet-String 12
PPO TYPE 3: Octet-String 4
PPO TYPE 2: Octet-String 20
PKW: Parameter ID/value
PZD: Process Data, cyclically transferred
PKE: Parameter ID (1st and 2nd octet)
IND: Sub-index (3rd octet), 4th octet is reserved
PWE: Parameter value (5th until 8th octet)
STW: Control word
HSW: Main setpoint
ZSW: Status word
HIW: Main actual value
