In order to understand the terms I invite you the look at the figures in the links. It deals with gthe graphical representation of connections in schematic wiring diagrams. It differs from previous representations by a diagonal connection.

Unter Zwangsverdrahtung versteht man die genaue Einhaltung der Zeichnung des Stromlaufplanes. Oft sind Bauteile nicht wirklich praxisfreundlich gezeichnet.
:
Ich hatte schon des Öfteren bei 24V+ die Verdrahtung von Relais, auf den Schließer eines Tasters, dann wieder Relais, dann wieder Taster usw. D.h. ich verlege meinen Draht immer zur Türe raus und wieder rein.
Hier wäre es viel einfacher erst die ganzen Relais zu brücken, da die eigentlich sowieso immer nebeneinander liegen und dann alle Taster in der Türe.

Precondition for applying this new functionality is the use of forced connection symbols: Symbols for forced connections are an approach offered by EB to specify the actually intended wiring and connectivity.
Voraussetzung für eine Anwendung dieser neuen Funktionalität ist dabei die Verwendung von Zwangsverdrahtungssymbolen: Zwangsverdrahtung ist ein von EB bereitgestelltes Verfahren zur Präzisierung der beabsichtigten tatsächlichen Verbindungsführung und Verdrahtung.

Diagonal Connections (Forced Wiring)
With the SHIFT key, diagonal connections can be generated during inserting connections. Change from Normal Wiring to "Forced Wiring.To change from normal connection s (T - connection) to forced wiring connections, there are two new commands available:
Incline clockwise || Incline counter clockwise
in the “Connections” toolbar.

Possibility 1
1. Check the target wiring in the multi-line schematic, meaning the use of the connection symbols (T-nodes, angles, etc.), and correct it if necessary.

The user copies parts of the FB-wiring from one device to another. It may happen that not all copied lines are inserted in the target wiring. Those are lines, which are connected to a variable in the source-wiring. (CR 39519)

Another highlight: the additional 'Netbased Wiring' model, an exciting approach to wiring. In EPLAN Electric P8 you will be able to define detailed connections within a network at the database level, irrespective of the graphical representation. In the schematic, logical point wiring instead of target wiring will be shown.

• With target specification: This default means, for example, that a T-node is drawn as target wiring. This T-node is also first placed and can then subsequently be changed to point wiring or a different target.

The term "destination wiring" is also used as synonym:

Destination wiring
The wiring of the schematic is done through destination wiring. On placing the elements, their pins are automatically connected to the lines, and destination wiring elements are inserted. In order to use this function optimally, snap (F5 key) and orthogonal drawing mode (F6 key) should be turned on so that the elements are placed within the grid.
The following destination wiring elements are available:
•Angle
•T-pieces
•Jumper
•Cross
•Arrows (termination point symbols)

As described elsewhere in this section, all wires are identified with marked heat shrink sleeves. This is a standard practice in industry and makes sense to carry over into the RV9A wiring system. I use a “destination” wiring scheme and wire number on each wire tag. When you look at the conductor the tags gives a short text description of where it is going and a wire number which is listed on my schematic for that system (or sub-system). As I build and wire, I “As-build” my schematics tyo make sure they accurately reflect what was actually done. Five years from now, I will have totally forgotten what I did so good reference documents are essential.

I also checked "constrained connection" About 8.880 results (0,59 seconds), but saw no relevant link on the first pages (mostly extended by "manager" or similar.

What about "constrained wiring"? About 26.100 results (0,41 seconds)

It also offers disconnect and knife disconnect terminal blocks with and without function shafts to enable the clear separation of signal currents in space-constrained applications.

Comments: No wiring diagram, but description of terminals or constrained space.
Conclusion: I should add "destination wiring" to my proposal, ordered by frequency (as not yet standardised):
