DeviceNet Interface
Overview
DeviceNet is a low cost and open industrial network which links industrial
devices (such as limit switches, photoelectric sensors and motor starters) to
machine controllers over the Controller Area Network (CAN). DeviceNet
eliminates expensive hardwiring and provides improved communication
between devices as well as important device level diagnostics.
The following sections describe the network Object Model (the interface
from the DeviceNet point-of-view).
Configuration
The unit supports the standard DeviceNet MAC ID and Baud Rate
selections. MAC ID and Baud Rates can be selected from user accessible
rotary switches or through DeviceNet configuration software.
See page 10-2 for more details. All configuration data is stored in
non-volatile memory.
Initialization
The unit provides standard duplicate MAC ID detection processing during
power-on initialization.
Group 2 Only Slave Operation
The unit supports allocation of the DeviceNet Group 2 Master/Slave
connection set through the Group 2 Unconnected message port.
Certification
The unit must be certified as a compliant DeviceNet device through an
ODVA certified testing facility. This device is not required to pass SEMI-SIG
optional conformance testing.
