9 Application examples
This section describes small application examples for the exchange of process data and
configuration of the UFI11A or a drive inverter connected to the UFI11A via the PCP in-
terface.
9.1 Control via process data
Control of the drive inverters via process data takes place by simple reading/writing of
the program addresses to which the INTERBUS process data of the drive inverters have
been written. A simple STEP7 program for the Simatic S7 looks as follows:
L W#16#0006
T PAW 144 //write 6hex to PO1 (control word = enable)
L 1500
T PAW 146 //write 1500dez to PO2 (speed setpoint = 300 1/min)
L W#16#0000
T PAW 148 //write 0hex to PO3 (has no function after factory setting)
You will find additional information concerning control of the drive inverters via the pro-
cess data channel, especially coding of the control and status word, in the manual for
the fieldbus unit profile of the corresponding drive inverter.
9.2 Parameter setting via the PCP interface
This section describes how you can read or write parameters and IPOS variables via the
standardized INTERBUS PCP services "Read" and "Write." The example is valid for all
INTERBUS interface modules of generation 4 (G4) and is explained in the PHOENIX
nomenclature. The coding examples described in the following sections are represented
in the same manner as described in the INTERBUS user manual "Peripherals Commu-
nication Protocol (PCP)" published by Phoenix Contact.
Prerequisites
You should have access to the following user manuals:
• INTERBUS user manual "Peripherals Communication Protocol (PCP)", PHOENIX
CONTACT, IBS SYS PCP G4 UM
• Manual for the fieldbus unit profile of the drive inverter connected to the UFI11A
