The DeltaV DeviceNet card conforms to the DeviceNet specification as an interface to a control application such as the DeltaV system. There is one port on the DeltaV DeviceNet card. In the DeltaV system, you use the DeltaV Explorer to perform the tasks described in this section.
The DeltaV system supports only DeviceNet devices that support I/O polling.
If one or more bits of a DeviceNet signal output tag are unused (masked) and sent to a slave device, the masked portion of the signal outputs may be driven to unexpected values. Also, if a control module that is writing to an output of a DeviceNet slave device is deleted in the DeltaV Explorer, the module's signal value persists until the device is deleted and the card downloaded. Refer to KBA NA-0900-0054 for more information on these scenarios.
