Operation

The virtual inputs and outputs that are to be transferred via DeviceNet are selected and
configured in the PNOZmulti Configurator. The base unit and the expansion module PNOZ
mc4p are connected via a jumper. The expansion module PNOZ mc4p is also supplied with
voltage via this jumper.
The station address and the transmission rate are set using DIP switches. After the supply
voltage is switched on or the PNOZmulti control system is reset, the expansion module
PNOZ mc4p is configured and started automatically.
LEDs indicate the status of the expansion module on DeviceNet.
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 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
}

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".
