Communicate with PanelView Terminals Chapter 7
Determine Connections to
PanelView Terminals
How you establish communication between a PanelView or PanelView Plus
terminal and a Logix5000 controller over a ControlNet network depends on how
you want to use controller connections.
Communication Type PanelView Standard PanelView Plus
Scheduled (always connected) Supported Supported in revision 3.2 and
later
Unscheduled (connected) Not supported Supported
Unscheduled (unconnected) Supported Not supported
A Logix controller supports up to 40 outgoing and 3 incoming unconnected
buffers. This limited number of incoming unconnected buffers limits how many
PanelView Standard terminals can request data from a controller.
When you use PanelView terminals with Logix5000 controllers over a
ControlNet network, remember these limitations:
•
A maximum of four PanelView Standard terminals can request data from a
Logix5000 controller.
•
The number of PanelView Plus terminals that can request data from a
Logix5000 controller is dependent on the number of available
unconnected buffers in the Logix5000 controller.
A typical PanelView Plus application uses 5 unconnected buffers in a
Logix5000 controller. With 32 unconnected buffers available at any time
in a Logix5000 controller, a maximum of 6 PanelView Plus terminals can
request data from a Logix5000 controller. Keep in mind, however, that if 6
PanelView Plus terminals are requesting data from a single Logix5000
controller, few unconnected buffers remain for anything else.
For scheduled connected communication, you must add the PanelView or
PanelView Plus terminal to the I/O configuration tree for the controller project.
