Use device matching to apply updates to your live hardware configuration based on changes you make in the Design view.
If SystemDesigner finds a matching device on the Design diagram, it automatically applies updates to the matching live device
in your project.
-
Navigate to the Design view.
-
Ensure that
Sync is set to
Enable hardware matching.
The Sync setting determines if you can apply changes in your project to matching live hardware in your system. Sync is set
to Enable hardware matching when you open SystemDesigner for the first time.
-
On the Design diagram, find the device you want to match with your live hardware.
If the device is not already on the Design diagram, find it on the palette and place it on the diagram.

Tip
Any device on the Live diagram that does not have a match on the Design diagram appears in the Unplaced Live Hardware palette.
-
Verify the match status of the device.
-
If the device does not have a match, configure the device on the Design diagram to match the device configuration on the Live
diagram.
The following device characteristics must match on both the Design view and Live view for SystemDesigner to identify a match.
Matching Criteria

Tasks
|
Device model
|
Search for the correct model on the Design view palette and the
Model drop-down menu in the
Identity section of the
Item tab.
|
Device name
|
Use the
Device name field in the
Identity section of the
Item tab to change the name of a device on the Design diagram.
|
Order of controllers and modules inside a chassis
|
If a device is partially matched, click
Update modules in chassis on the
Item tab to update the order of the modules in the chassis to match the corresponding live chassis. This button only appears when
Sync is set to
Enable hardware matching.
|
Device port connections
|
Ensure port connections are identical to those of the device on the Live diagram.
|
After you enable hardware matching and configure the device on the Design diagram to match the configuration of the live hardware,
SystemDesigner automatically matches the devices.
