9-2        Communicate with a PanelView™ Standard Terminal

You have 3 options to send data to/from a PanelView terminal:

communicate with the PanelView terminal 
using the reqular I/O communication of the 
the DeviceNet network

I/O slave

• Easiest to use—requires no additional 

programming.

• Use this as your first choice.
• Higher priority on the network than explicit server 

and explicit client updates.

communicate with the PanelView terminal 
based on conditions in your logic

explicit server

• Provides additional data when you use up the I/O 

slave assemblies.

• Lower priority on the network than I/O slave 

updates.

use the PanelView terminal to get or set a 
parameter of a device on your DeviceNet 
network (not a controller)

explicit client

• Does not use the controller or scanner.
• Lower priority on the network than I/O slave 

updates

• You define the input and output 

sizes, up to 64 words. 

• Assembly instance 1 gives 

input data to the controller.

• Assembly instance 2 gets 

output data from the controller.
