The baud rate for each device must match the baud rate set for the DeviceNet master. Do not attach a device if you do not know the baud rate and be sure that the baud rate is correct before attaching a device to the network. The manner in which the baud rate is set depends upon the device type:
Some devices use switches on the front of the device to configure the baud rate. Consult the device documentation for information.
The EDS file for some devices supports a baud rate parameter for configuration through DeltaV software.
Some devices support the use of the DeviceNet Object's baud rate attribute to set the baud rate. (Consult the device's conformance documentation.) Use DeltaV Diagnostics to set the baud rate for this type of device. Be sure to disable I/O Polling for the device and to reset or power cycle the device for the baud rate to take effect.
If the device supports neither switches nor the baud rate parameter, use a diagnostics tool to configure the baud rate. Consult the device documentation for information.
The EDS file for some devices supports an autobaud rate parameter for configuration through DeltaV software. Enable this parameter and attach the device to the network.
