Get Data links allow you to get data from a tool or task in a vision program and display or use it in a control.
The link is created between the Impact Connector control and the vision program tool or task. For example,
you can link to a Basic tool’s calculated value, then link that to a Numeric Display control so the Control
Panel operator can see the value on the Control Panel. See “Links between CPM and VPM” on page 4-15 for
more details on links.The color of the Link name indicates the link’s status:
• Magenta - Normal
• Red - unresolved (e.g. due to no loaded vision program or no connection to a device)
• Black - Links from more than one control
Method Links
Note: If the Control Panel is not connected to an Impact device, you cannot create links.
Method links allow you to create an action in a device, vision program, task, or a tool in a vision program.
The link is created between the Impact Connector control and the device, program, task, or tool. For exam-
ple, you can link to a device’s online state, then link that to a button control’s action so the Control Panel
operator can change the device’s online status by clicking that button on the Control Panel. See “Links
between CPM controls” on page 4-19 for more details on linking.
• Blue - Normal
• Red - unresolved (e.g. due to no loaded vision program or no connection to a device)
• Black - Links to more than one control
Data Transfer Links
Note: If the Control Panel is not connected to an Impact device, you cannot create links.
Data transfer links accept data from a Data Transfer tool in a vision program. See “Links between CPM and
VPM” on page 4-15 and “Data Transfer” on page 3-219 for more details.
• Magenta - Normal
• Red - unresolved (e.g. due to no loaded vision program or no connection to a device)
• Black - Links from more than one control
