CPM and VPM Linking
In CPM, links can be made between vision programs and tasks on the Impact device and Control panels on
the host. The links create an information path to the device through the Impact Connector control. The vision
program or task you want to link to must be loaded on the Impact device, and CPM must be connected to
that device, before links can be made. (See “Connect to device” on page 4-2.)
How Impact Connector controls are created
Each Impact Connector control can connect to only one Impact device at a time, so you need one Connector
for each device that the control panel will access. You can put one Connector control on each panel or put
multiple controls on one panel.
When you create a link from VPM to CPM, Connector controls are automatically added and connections are
made in the following order:
1. If no Impact Connector exists in the application, one is added and the Connector control connection is
made to the Impact device’s IP address.
2. If a Connector with the current device’s IP address exists in the application, that Connector is used. If
more than one with that address exists, a list is displayed.
3. If a Connector with a blank IP address exists in the application, the IP address is set and that Connector
is used. This happens when a template that contains a Connector is used.
To add additional Impact Connectors, click and drag the control from the palette to the canvas. You will need
to manually enter the desired device’s IP address in that Impact Connector’s IP Address property, then set
the Connected property to True.
NOTES: When you use multiple Impact Connector controls on a control panel, it is possible to unknow-
ingly have controls on the same panel connected to different Impact devices. Check the IP Address property
value on the Connector controls if some controls are not responding the way you believe they should.
If you delete a control or a Connector on a panel, any Connectors on that control panel that have no links to
them are deleted automatically.
