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 m
ES CANopen 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 control system
PNOZmulti 2 is reset, the expansion module PNOZ m ES CANopen is configured and star-
ted 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
Data access
The data is structured as follows:
}
Virtual data
–
Input area PNOZ m ES CANopen
The values for the inputs are set as an output in the Master and transferred to the
PNOZmulti 2.
–
Output range PNOZ m ES CANopen
The outputs are configured in the PNOZmulti Configurator and transferred to the
Master.

Status of LEDs:
LED status 1 Output Byte
The LED status of the base unit can be requested directly as follows
–
Bit 0 = 1: LED OFAULT is lit or flashes
–
Bit 1 = 1: LED IFAULT is lit or flashes
–
Bit 2 = 1: LED FAULT is lit or flashes
–
Bit 3 = 1: LED DIAG is lit or flashes
–
Bit 4 = 1: LED RUN FS is lit
–
Bit 5: Reserved
–
Bit 6 = 1: LED RUN ST is lit (not for PNOZ m B0)
–
Bit 7: Reserved
}
Data exchange is displayed in Bit 5.

Polling the payload data: 2 Bytes with the table number and segment number are sent
by the Master for access to the payload data table (15 Bytes are returned to the Mas-
ter).
The document "Communication Interfaces" contains detailed information
}
on data exchange (tables, segments) in the section entitled "Fieldbus modules",
}
on the virtual data in chapter "Service Data Objects (SDOs)" for PNOZ m ES CANopen.
