18.1.4 Open DeviceNet Vendor Association, Inc. (ODVA)
ODVA is an independent supplier organization that manages the DeviceNet and EtherNet/IP specification and
supports the worldwide growth of the Common Industrial Protocol (CIP).
18.1.5 Rotary Switch Configuration
Two rotary switches configure the DeviceNet MacID, and one rotary switch configures the baud rate. Use a
small screwdriver to change the switch settings. The NODE ADDRESS (MAC ID) rotary switches are shown in
Figure 56, and the DATA RATE rotary switch is shown Figure 57.
Figure 56 - MAC ID rotary switch layout
Use the NODE ADDRESS switches to select the DeviceNet MAC ID address. The valid range of addresses is
0 – 63. All combinations above 63 set the device address to the last address the device was powered up at
and allow software configuration tools to modify the MAC ID address.
