4.1
Functions
The data to be transferred via INTERBUS LWL is selected and configured in the
PNOZmulti Configurator. The base unit and PNOZ fieldbus module PNOZ mc5.1p are con-
nected via a jumper. The fieldbus module is also supplied with voltage PNOZ mc5.1p via
this jumper. After the supply voltage is switched on or the safety system PNOZmulti is re-
set, the fieldbus module PNOZ mc5.1p is configured and started automatically.

Input and output data
The data is structured as follows:
}
Input area
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".
