INTERBUS Interface

5.5

PCP interface

The UFI11A fieldbus interface offers a standardized interface for parameter setting
using the "Peripherals Communication Protocol" (PCP). This communications channel
gives you full access to the parameters of the UFI11A fieldbus interface and the drive
parameters of the inverters connected to the UFI11A.

Overview of basic 
structure

The PCP channel must be set to one, two or four words using the DIP switches on the
UFI11A to enable access to the parameter values of the UFI11A fieldbus interface or the
inverter. Changing the number of PCP words varies the access speed to parameter va-
lues via the PCP channel. The PCP interface is implemented using PCP version 3.0 in
the UFI11A.

PCP services

The UFI11A fieldbus interface supports the PCP services shown in Fig. 10. However,
only the following services are relevant for setting parameters: 

•

Establishing the connection (Initiate)

•

Reading of parameter values (Read)

•

Writing of parameter values (Write)

•

Cancelling the connection (Abort)
