CAN Networking and Diagnostics
Node Version Information
The CAN Diagnostics screen displays the software version, software revision and program number of each
node detected on the CANbus.
Readdressing the Nodes
If the field computer is unable to detect a CANbus node on startup, troubleshoot the CANbus and the node
(see the CAN Troubleshooting section on page 34) and then readdress the CANbus:
Note: Only product nodes need to be addressed (single product, dual product, motor control, etc.).
1. Select the Information icon in the upper, right corner of the Home screen.
2. Touch the icon on the About Envizio Pro screen to display the CAN Diagnostics screen.
3. Touch the button to begin readdressing the product control nodes.
4. When prompted to cycle power on the first product node, disconnect the logic power from the product node
to be controlled as Product 1. After approximately 3 seconds, reconnect the node’s logic power. The field
computer should have recognized the node as ‘Product 1.’
5. If additional product nodes are installed in the CANbus, repeat step 4 to readdress the remaining product
nodes as necessary
6. Touch the Accept icon to finish readdressing the product nodes.
