In order to route connections that run between different identification structures (for example connections between two enclosures with different location designations) the connected functions have to exist as topology functions. EPLAN supports you here by providing the possibility to manually or automatically generate these topology functions and the associated routing paths.
The starting point of this procedure are the structure routing points. These represent a specific identification structure. At a structure routing point you either manually select the desired functions from which topology functions are to be generated, or you have them generated automatically. Through subsequent routing you create routing connections between the functions in the various identification structures.
If you want to place the topology functions and routing paths subsequently, first place the unplaced topology functions on the schematic page of the routing point and then use the functionality of the automatic placement of unplaced routing paths.
This section describes the procedure for routing connections between two different identification structures. Connections between several different identification structures can, however, be routed by the same means. In this case further structure routing points are required.
Preconditions:
- You have opened a project.
- You have inserted two structure routing points and connected these with each other through a routing path. The structure routing points and the routing path can, but do not have to be, placed on a topology page.
- The required multi-line or single-line functions already exist and are connected with each other.
Routing connections with the automatic generation of the topology functions
- Mark the two structure routing points on the topology page of in the topology navigator.
- Select the following commands: Tab Connections > Command group Topology > Drop-down button Generate > Generate functions automatically.
Unplaced topology functions are generated from the multi-line or single-line functions that correspond to the identification structure of the marked structure routing points. The resulting topology functions are connected via unplaced routing paths with the structure routing points. - Mark the multi-line connections (for example in the connections navigator) or the topology functions in the topology navigator, or simply mark the project in the page navigator, and select the following commands: Tab Connections > Command group Topology > Route. Unplaced routing connections are generated between the functions in the first identification structure (selected at Structure routing point 1) and the functions in the second identification structure (selected at Structure routing point 2).
Tip:
You can specify a filter in the Connected structures tab in the property dialog of a structure routing point. You can use such a filter to limit the generation of the unplaced topology filter to a subset of the functions that correspond to the identification structure of the marked structure routing point and to the structure routing points connected to these. You can, for example, filter by functions that have a specific location designation or that have a specific function definition.
Routing connections with the manual generation of the topology functions
- Mark the first structure routing point on the topology page of in the topology navigator.
- Select the following commands: Tab Connections > Command group Topology > Drop-down button Generate > Generate functions manually.
- Select the desired functions of the first identification structure for which the topology functions are to be generated in the Main functions without topology area in the Generate topology functions dialog.
- Use the arrow button to move the marked function into the Connected topology functions list.
- Click [OK]. The unplaced topology functions are generated and connected through unplaced routing paths with the structure routing point.
- Use the same procedure to generate unplaced topology functions and routing paths for the second identification structure at the second structure routing point.
- Mark the multi-line connections (for example in the connections navigator) or the topology functions in the topology navigator, or simply mark the project in the page navigator, and select the following commands: Tab Connections > Command group Topology > Route. Unplaced routing connections are generated between the functions in the first identification structure (selected at Structure routing point 1) and the functions in the second identification structure (selected at Structure routing point 2).
Tip:
With the command Generate functions manually you have the possibility at any time to open the dialog Generate topology functions (command path: Tab Connections > Command group Topology > Drop-down button Generate > Generate functions manually). There you can view the generated topology functions and, if required, change them subsequently. The automatically generated topology functions are also displayed in this dialog.
Placing topology functions
- If you want to place the previously generated unplaced topology functions and routing paths, first open a topology page in the graphical editor and there place the two structure routing points and the connecting routing path (in as far as not yet done).
- Mark the unplaced topology functions in the topology navigator and select the Place > Topology popup menu items. The first function hangs on the cursor.
- Place the functions consecutively on the topology page - by clicking with the left-hand mouse button.
- Mark the unplaced topology functions in the topology navigator and select the Place > Automatic popup menu items. The topology functions are connected consecutively with the corresponding structure routing point.
