Wiring > Import of Carry-Over Wiring
Merging a Slot and Interface
Connector
After importing carry-over wiring, you may need to modify an existing, imported device to add connections to new signals. You do this by creating a system design that contains the existing devices that need to be changed as well as any new devices. When you associate that with the Capital Systems Integrator design and place the devices in slots, you have two representations of the existing device: a device in a slot and an interface connector (created during the harness import). You must merge those representations.
Note
See High-level Flow for Importing Carry-Over Wiring for the full carry-over wiring flow, including modifying an existing device.
Prerequisites
You must have placed the modified device from the system design in a slot.
Procedure
Drag and drop the interface connector over the slot.
Results
The interface connector is removed and the wiring connects to the slot connector.
If the slot has a single slot connector, the wiring connects to that.
If the slot has multiple slot connectors, a dialog box asks you to select the required connector for merging.
Wires that were connected to the interface connector re-connect to the cavities of the slot connector, matched by signal.
If the slot connector has multiple cavities carrying the appropriate signal, the system selects a cavity as follows: If there is a cavity with a matching name, it uses that.
If there is an unconnected cavity, it uses that (or the first of multiple, unconnected ones).
If neither of the above apply, the first matching cavity is used.
The system considers new signals unrouted and connects them to new cavities.
If the interface connector has a wire from a signal that does not exist at the slot, the wire is deleted (and a message displays in the Output Window).
