DeviceNet Object

Class Code: 03hex

The DeviceNet Object is used to provide the configuration
and status of a physical attachment to DeviceNet.

The MACID attribute provides the network address for the
device. If the rotary switches used to specify the device
MACID are set to a valid MACID, i.e. a value from 0 to 63,
the MACID attribute shall have Get Only access. If the
rotary switches are set to the programmable mode, the
MACID attribute shall have Get and Set access.

The Baud Rate attribute specifies the data rate for the
device. If the rotary switch used to set the data rate speci-
fies a valid data rate, i.e. 125, 250, or 500K Baud, the Baud
Rate attribute shall have Get Only access. If the rotary
switches are set to the software programmable mode, the
MACID shall have Get and Set access.

The Allocate Master/Slave Connection Set service of the
DeviceNet object shall be a required service for all devices.
This implies a requirement that all devices are Group 2
devices on the DeviceNet network. Additionally, all devices
shall support, as a minimum, the Explicit connection and
the I/O Poll connection in the Master/Slave connection set.

The Release Master/Slave Connection Set service of the
DeviceNet object shall be a required service.

Refer to the DeviceNet Specification (Vol. I, Sec. 5-5) for
complete requirements.
