Function description
4.1
Operation
The virtual inputs and outputs that are to be transferred via CANopen are selected and con-
figured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mmc6p are connected via a jumper. The station address and the transmission rate are set
using rotary switches. After the supply voltage is switched on or the PNOZmulti control sys-
tem is reset, the expansion module PNOZ mmc6p is configured and started automatically.
LEDs indicate the status of the expansion module on CANopen.
The configuration is described in detail in the PNOZmulti Configurator's online help.
4.2
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".

to the CANopen inputs/outputs
Virtual inputs on PNOZmulti Configurator
i0 ... I7
i8 ... i15
i16 ... i23
Input data CANopen
Byte 0: Bits 0 … 7
Byte 1: Bits 0 … 7
Byte 2: Bits 0 … 7
