Objects on a display are wire framed

If an object with a tag or expression connection has a broken connection to its data provider, the object is shown as a wire frame. Wire-framed graphic objects on a display indicate that Live Data items cannot be acquired from the data providers (HMI server,
FactoryTalk® Linx
, or OPC server).
If graphic objects on a display are wire-framed, consider the following potential causes and remedies.
A device inhibits data communications
If a device, such as a ControlLogix controller, inhibits data communications, graphic objects will be shown as wire frames.
  1. In
    FactoryTalk Linx
     communications tree, right-click the device and select
    Properties
    .
  2. In the
    Device Properties
     dialog box, clear the
    Inhibit Data Communications
     checkbox.
FactoryTalk View
 server is not running
FactoryTalk ViewPoint
 Live Data acquisition is dependent on HMI services. If these services are not running, graphic objects associated with live data items will be wire-framed.
All necessary HMI services start automatically when
FactoryTalk View
 server startup type is set to "Load and run startup components when operating system initializes". However, if the startup type is set to "On demand", HMI services must be started manually by either opening
FactoryTalk View
 client or
FactoryTalk View Studio
.
Networking and communications failure
If networking and communications have failed on the host computer, the
FactoryTalk ViewPoint
 server will be unable to communicate with the
FactoryTalk View
 Live Data servers.
  • If possible, configure and launch a
    FactoryTalk View
     client instance on the same computer that runs the
    FactoryTalk ViewPoint
     server and observe its behavior.
    If the same graphic objects are wire-framed, the problem is not in the
    FactoryTalk ViewPoint
     but at the lower levels such as the networking and communications.
FactoryTalk ViewPoint
 host computer name contains an underscore (_)
If the
FactoryTalk ViewPoint
 server contains an underscore character in its host name, a
FactoryTalk ViewPoint
 client connecting to it using the syntax
http://computer_name/ftvp
 will show all objects as wire frames. This is not a product issue but the limitation of the web platform the product relies on.
  • Enter the IP address in the URL syntax: http://xxx.xxx.xxx.xxx/ftvp.
    If the site has an HTTPS binding, enter
    https
    instead of
    http
    .
