This DeviceNet Object is meant to provide the configuration and
status of the physical node connected to DeviceNet network.
Supported Service code:
0Eh = Get_Attribute_Single: used to read connection class attribute
value.
10h = Set_Attribute_Single: used to write connection class attribute
value.
Supported Instance: 01h = Explicit Message
03-01-01 Node Address
[USINT, ro]
This attribute contains the MAC-ID of the device.
To set the node address see section “4.7 Node address: DIP B”
03-01-02 Baud rate
[USINT, ro]
This attribute sets the baud rate.
Binary value Baud rate
00 125 Kbit/s
10 250 Kbit/s
01 500 Kbit/s (default)
To set the baud rate see section “” on page 10.
