4.1 Operation
The virtual inputs and outputs that are to be transferred via EtherCAT are selected and con-
figured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mmc11p are connected via a jumper. After the supply voltage is switched on or the
PNOZmulti control system is reset, the expansion module PNOZ mmc11p is configured and
started automatically.
The connection to EtherCAT is made via the two RJ45 sockets.
LEDs indicate the status of the expansion module on EtherCAT.
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".
4.3 Assigning the inputs/outputs in the PNOZmulti Configurator
to the EtherCAT inputs/outputs
Virtual inputs on PNOZmulti Configurator i0 ... I7 i8 ... i15 i16 ... i23
Input data EtherCAT Byte 0: Bits 0 … 7 Byte 1: Bits 0 … 7 Byte 2: Bits 0 … 7
Virtual outputs on PNOZmulti Configurator o0 ... o7 o8 ... o15 o16 ... o23
Output data EtherCAT Byte 0: Bits 0 … 7 Byte 1: Bits 0 … 7 Byte 2: Bits 0 … 7
The number of virtual inputs and outputs can be extended to 128 (see document "Commu-
nication Interfaces" in the section entitled "Fieldbus modules")
