DeviceNet
DeviceNet is an open network protocol for connecting the 4050 to PCs, PLCs or embedded
controllers through a single cable interface. Signals from the 4050 can be used for external
diagnostics and troubleshooting. Smart devices, such as sensors, push buttons, motor
starters, simple operator interfaces, drives and other weight modules can also be linked with
DeviceNet, and third-party I/O can be easily added to any system. You can monitor multiple
plant-floor devices from one display and reconfigure them as your needs change or service
them as required.
Configuring DeviceNet from the Web Interface
Step 1. From the Options Page select DeviceNet to
display the DeviceNet Setup page.
Step 2. Select the Baud Rate from the pull-down list. See
your Network Administrator if you don’t know the
correct Baud Rate.
Step 3. In the Node text field, type the Node address of the
instrument. Our example shows a Node Address 3.
Step 4. In the Bytes Input text field, type the bytes input
value you need for your application. Our example
shows 32 Bytes.
Step 5. In the Bytes Output text field, type the bytes output
value you need for your application. Our example
shows 32 Bytes.
Step 6. Click Save Parameters to save the configuration.
The status of the DeviceNet Connection appears at
the bottom of the display. If the instrument is
connected to the DeviceNet Network, the message
reads: “Yes DNET Connection. LED On.” If not, it
reads: “No DNET Connection. LED Off.”
