Functions
The virtual inputs and outputs that are to be transferred via the fieldbus Ethernet POWER-
LINK are selected and configured in the PNOZmulti Configurator. The base unit and the
fieldbus module PNOZ mc12p are connected via a jumper. The fieldbus module is also
supplied with voltage via this jumper. After the supply voltage is switched on or the control
system PNOZmulti is reset, the fieldbus module PNOZ mc12p is configured and started
automatically.
LEDs indicate the status of the fieldbus module on the fieldbus Ethernet POWERLINK .
The configuration is described in detail in the PNOZmulti Configurator's online help.

Input and output data
The data is structured as follows:
}
Input area
The inputs are defined in the Managing Node and transferred to the PNOZmulti. Each
input has a number, e.g. input bit 4 of SDO 2100:02 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 state of output o0 is stored in Bit 0 of SDO
2000:01.

Detailed information on data exchange is available in the document "Communication Inter-
faces" in the section entitled "Fieldbus modules".
The number of virtual inputs and outputs can be extended to 128 (see document "Commu-
nication Interfaces" in the section entitled "Fieldbus modules")
