6.3 Parameter orders with Compact PCP
Parameter data are divided into individual parameter blocks and transmitted in sequence. This is implemented by
the PCP (Peripherals Communication Protocol). The transmission of a parameter can therefore take several bus
cycles. This is slower in comparison to process data transmission.
The IBS technology unit has an integrated 1 word PCP channel.
The PCP is implemented in the Compact PCP version.
Compact PCP has limited functionalities in comparison to the full PCP version. The following commands are
supported: initiate, read, write
The Phoenix Contact software for the InterBus master offers full Compact PCP support from firmware
4.60 onwards.
The object index (OI) used in PCP is omitted here.
6.3.1 Frequency inverter parameters (2000
hex
-23E7
hex
)
All FI parameters can be accessed directly via the parameter channel.
With InterBus protocol, the inverter parameters are mapped in the range 2000
hex
to 23E7
hex
(= 8192
dec
to
9191
dec
), i.e. when parameterisation is carried out via the bus, the parameter numbers must be added to
the value 2000
hex
(e.g. P508
→ obj 21FC
hex
).

6.3.2 Drive profile as per DRIVECOM21
The following parameters are only valid if the frequency inverter parameter drive profile (P551) is
switched on. The profile is not valid in PPO type 2.
The objects remain valid for the 1
st
parameter set only.
The DRIVECOM objects are described in more detail in Chap. 6.4.

• The control word 6040 or the setpoint 6041 is only valid when object 6002 (PA data enabled) is
switched off (not equal to 0xFF). Otherwise (6002=FF) control word and setpoint of the process
data channel are valid.
