DeviceNet Add-on
ADwin
10 DeviceNet Add-on
The add-on Gold II-DeviceNet provides a fieldbus node with the functionality of a
DeviceNet slave. All settings are done via software.
Functions description
After power-on the fieldbus node must be initialized. The initialization determines the
station address (slave node address) on the DeviceNet, the baudrate, and the size of
the input and output areas.
There is a range each for data input and data output; each range has a maximum size
of 255 bytes. Please note, that the terms "input" and "output" are used as the fieldbus
controller (slave) sees them.
You set the number and length of input and output areas separately.
Hardware
The pin assignment of the DeviceNet connector refers to
the specification of the Open DeviceNet Vendor Associ-
ation (ODVA).
The DeviceNet has to be terminated at its physical
beginning and at the end of its segments by an active
terminator. If required, you have to add the terminator yourself at the appropriate data
lines of the fieldbus node or use an appropriate connector with integrated terminator.
Left and right of the connector, there are two LEDs, which display the operation status
of the node in the DeviceNet: network status (NP) and module status (MS; module
stands for the node here).

Projecting the DeviceNet
You are projecting the DeviceNet with a configuration tool suitable for the bus master.
Look for the process description of bus projection in the documentation of the configu-
ration tool.
For projecting, the file
324-8172-EDS_ABCC_DEV_V_2_3.eds
(electronic data
sheet) is provided in the folder
C:\ADwin\Fieldbus\DeviceNet
.
Make sure that you use the same settings (station address, baudrate, number and
length of input and output data) for projecting as you have done for initialization in
ADbasic
with the instruction
Init_DeviceNet
.
Please note, that the terms "input" and "output" may have reverse meanings in
ADbasic
(slave) and in the configuration tool (master). Also, the order of setting inputs and out-
puts may be of importance in the configuration tool.
