Balluff Network Interface / DeviceNet Fieldbus Distributor
10
Getting Started
The bus connection is made using the 7/8“ sockets DeviceNet IN and DeviceNet OUT. The
address is set on the address switch.
DeviceNet IN (7/8“ male)
DeviceNet OUT (7/8“ female)

Connect ground conductor to FE terminal.
Connect the incoming DeviceNet line to DeviceNet IN.
Connect termination resistor to DeviceNet Out in the case the module is the end of network,
otherwise connect continuing line for successor DeviceNet modules.
Note!
Each DeviceNet segment end must be installed with a termination resistor. Unused
sockets must be fitted with cover caps to ensure IP 67 protection rating.
The baud rate and DeviceNet address are set directly on the BNI DNT-... using BCD switches.
The following baud rates (1) are available:
Switch position 0: 1 kbs
Switch position 1: 0 kbs
Switch position : 00 kbs
Switch position : Autobaud (default setting)
Switch position 4-9: Programmable
Permissible address range 0...6.
Available addresses (address 64 and higher) are treated like address 99 (software address)
Each node must have a unique address () assigned to it.
The standard address in the EDS file should be 6 for automatic addressing.
The address is read once after power is turned on.
Any change to the address does not become effective until power is reset on the module.
