Assigning Entry Ports
Entry Ports
An entry port is a coordinate system of a connector that you designate as accessible to route a wire, cable, ribbon, or bundle. For every entry port on the connector, there must be an ENTRY_PORT parameter. The system creates this parameter automatically when you designate the connector. Entry ports represent the pins in pin-to-pin cabling connections. A conductor always leaves an entry port tangent to the positive z-axis at the origin of the entry port coordinate system. You can define any coordinate system on a part as an entry port. Typically, you do this when you designate the part as a connector.
 |
To be an entry port, the coordinate system must be at the top level of the model representing the component. That is, it must be at the part level for a part or at the top level of a subassembly.
|
After you designate a coordinate system as an entry port, you can assign this coordinate system to a specific pin on the connector. The coordinate system is required for autorouting individual conductors within a cable but not for normal routing.
Format for defining the ENTRY_PORT parameter
Define the ENTRY_PORT parameter as follows:
ENTRY_PORT coord_sys_name cable_type internal_length
where:
• coord_sys_name is the name of that entry port's coordinate system (for example, CSO).
• cable_type can be WIRE, ROUND, or FLAT.
• internal_length is the length of cable run inside the connector. This value is accounted for in any display of cable length. internal_length is optional.
The following is an example of the ENTRY_PORT parameter:
ENTRY_PORT CSO WIRE 2
About Defining Parameters for Entry Ports in Components
When you create or define a cabling component, you can apply entry port information to relevant coordinate systems by assigning standard parameters. You define the parameters as shown in the following table. The pins identify the individual ports that connect to a wire after you define the parameters on a connector.
When you define parameters for entry ports, you can simplify the routing process.
When logical data is imported through the Cabling Data Tool, the system automatically identifies coordinate systems with entry port parameters and displays them as entry ports in the Cabling Data tool. The designation state of each entry port reflects the imported logical information and is available for review or modification.
• Providing the connector model name in Creo Schematics is enough logical data information when you export the design to Cabling.
• When you route cables, the system automatically finds the coordinate systems with relevant entry port parameters.
For each coordinate system used as a port define the following parameters:

Pin declaration on a connector is handled by a list of pin names based on the value entered. The value for the pin name should be an integer or a string of integers. After you have entered the value, the pins are arranged in the ascending order of the values specified in the table. The necessary pins for the conductor are mapped to the respective entry port.
To Designate a Coordinate System as an Entry Port
1. Click 
Cabling Data. If logical data has been imported, you can use 
to automatically populate connectors and entry ports or you can use 
to manually designate components.
Cabling Data. If logical data has been imported, you can use to automatically populate connectors and entry ports or you can use to manually designate components.2. Expand the Entry Ports table listing all coordinate systems associated with the connectors.
3. Select the coordinate system that you want to assign as entry ports to carry the cable and wire on the connector.
a. In the Entry Port Name column select the coordinate system on the connector.
b. Switch the value from FALSE to TRUE in the Designated Entry Port column.
c. Select a port type in the Type column.
▪ Wire allows to route a single wire. You cannot route a cable or multiple wires to a wire entry port.
▪ Round and Flat allows multiple connections. A ribbon cable is routed to a flat entry port.
d. Set Internal Length.
e. Click Apply to designate the connector.
The internal length is not actually routed. It is specified in a numerical parameter for each entry port. These lengths are automatically added to the routed length of a wire when length information is provided.
When you designate one or more coordinate systems as entry ports on a connector, the parameters EP_TYPE and INT_LENGTH are added for each entry port at the entry port level of the connector in the Electrical Parameters dialog box.
To Assign an Entry Port to a Pin Number
1. Click 
Cabling Parameters.
Cabling Parameters.2. Select one or more connectors with the pins you want to associate. The Electrical Parameters dialog box opens.
Ensure that the NUM_OF_PINS parameter has an appropriate value to be assigned to the entry ports.
3. Under Display For, click Pins.
4. If no columns are displayed, click > to add the required parameters.
5. In the Value box, for each pin, type the name of the coordinate system you want to associate with the pin as a value for the ENTRY_PORT parameter or select the entry port name from the list.
