Function description
4.1
Operation
The virtual inputs and outputs that are to be transferred via PROFIBUS are selected and
configured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mmc3p are connected via a jumper.
The station address is set via rotary switches. After the supply voltage is switched on or the
PNOZmulti control system is reset, the expansion module PNOZ mmc3p is configured and
started automatically.
LEDs indicate the status of the expansion module on PROFIBUS.
The configuration is described in detail in the PNOZmulti Configurator's online help.
INFORMATION
The GSD file is available on the Internet at www.pilz.de.

Input and output data
The data is structured as follows:
}
Input range
The inputs are defined in the master and transferred to the PNOZmulti. Each input has
a number, e.g. input bit 4 of byte 1 has the number i12.
}
Output range
The outputs are defined in the PNOZmulti Configurator. Each output that is used is
given a number there, e.g. o0, o5... The status of output o0 is stored in bit 0 of byte 0;
the status of output o5 is stored in bit 5 of byte 0 etc.
}
Output range only: Byte 3
Bits 0 … 4: Status of LEDs on the PNOZmulti
–
Bit 0: OFAULT
–
Bit 1: IFAULT
–
Bit 2: FAULT
–
Bit 3: DIAG
–
Bit 4: RUN
Bit 5: Data is being exchanged.
Detailed information on data exchange (tables, segments) is available in the document
"Communication Interfaces" in the section entitled "Fieldbus modules".
