Network Topology; Configuring The Baud Rate And Dvn Address; Configuration Of Process Data - Burkert 8681 Guide Rapide

No internal cabling work is required for any of the DeviceNet designs.
However, you will require the correspondingly assembled cable sets
with the pin assignments described below:

strip - see manual, chapter „Con-
nection of an external initiator".

10.6. Network Topology
When installing a DeviceNet system, ensure that the terminating circuit
of the data lines is correct. The circuit prevents the occurrence of
interference caused by signals reflected onto the data lines.
The trunk line must be terminated at both ends with resistors of 120
Ω
and 1/4 W power loss (see the manual, chapter „Network Topology
of a DeviceNet System").
10.7. Configuring the Baud rate and
DVN address
8 DIP switches are available for configuration:
• DIP switches 1 to 6 for DeviceNet address
(factory setting: 63, i.e. DIP 1 - 6: on)
• DIP switches 7 to 8 for Baud rate
(factory setting: 125, i.e. DIP 7 + 8: off)
Further configuring - see manual, chapter „Configuring the
DeviceNet address / baud rate"
10.8.

Configuration of Process Data

To transmit process data via an I/O connection, 2 static input and
1 static output assembly can be selected, see manual, chapter "Con-
figuration of Process Data"
„Address" in the table describes the data attribute of the assemblies
for read access (class, instance, attributes).
