Chapter 4 Automatically Configure a DeviceNet Network
3. Connect the rest of your devices to the network one at a time.
• Out of the box, a DeviceNet device is preset for address 63. Connect
and set the devices one at a time to set the scanner’s DeviceNet
address. Otherwise the address conflicts may prevent communication
with them.
• If a device has a switch to set its baud rate, set the switch to
autobaud, if available. Otherwise, set the device to the baud rate of
the network.
• After you change the address or baud rate of a device via a switch,
cycle power to the device.
• If a device has no switch or pushbutton for its address or baud rate,
see Set the Baud Rate of a Device Via a DeviceNet Configuration Terminal
below.
• After you set the address of a device, check its network status
indicator. Typically, a solid red indicator means an address conflict or
problem with the baud rate.
Set the Baud Rate of a Device Via a DeviceNet
Configuration Terminal
Follow these steps to set the baud rate for your DeviceNet network via the
DeviceNet Configuration Terminal, catalog number 193-DNCT. For the rest
of the chapter, the terminal is referred to as the 193-DNCT terminal.
1. Connect the 193-DNCT terminal to the network. The following display
appears for 10 seconds which shows the unit setup and the baud rate
and node number values it has determined.
