Connections are numbered offline based on the connection data generated. The connections are automatically regenerated before numbering.
Placing connection definition points and numbering connections are two processes each with their own settings. In general, you must first place the connection definition points and then number the connections. The connection designations are then written on the placed connection definition points.
Connection numbering and the connection definition points generated in the process can also be deleted.
Formatting
There are connection groups that each have different scopes and differently formatted connection designations. Normally connections are grouped by the type of devices they are connected to, for example general connections, connections attached to PLCs or terminals, etc. Using the Grouping property, free groups of connections can be additionally defined. This property is available to connections, connection definition points, potentials, signals, and potential definition points.
Connected function properties (device properties) as well as signal and potential properties can be used in the formatting. In addition, a counter and a subcounter can be specified.
Format groups
Certain groups of connections within the function definitions selected for numbering can be formatted differently. For example, designations for connections attached to a PLC differ from those for connections attached to a plug. For this reason, you can define format groups and assign numbering formats to them. A format group consists of one connection group whose scope you can define.
Extent
The scope defines a range of connections that share the same connection designation format, for example individual connections, nets, signals, potentials, etc. For the "Net" setting, all connections in a net are designated in the same way (except if a subcounter is installed, in which case the designations differ as a result of it). The subcounter value is unique within the entire format group, i.e. it is incremented automatically if the connection designations are otherwise identical.
A scope can also be established for a subcounter. This way it is possible to not only allocate a subnumber for each individual connection within a range of connections, but also for every net within a range of connections.
Details of the scope up to the actuator / sensor
For connections attached to PLC connection points you can select the "Up to each sensor / actuator (net)" option. The search for sensors and actuators then begins at the following function definitions or connection points:

Depending on the signal type on the connection points. |
For the function with variable connection number (300/99/1) the system checks the connection points signal type for an input or output. The following signal types are possible:
- Digital input
- Digital output
- Analog input
- Analog output
An actuator or sensor will be found depending on the connection point in question. The actuators and sensors to be found depend on the function definition. The signal type is checked on all connection points for all functions.
For the following signal types the connected function is interpreted as an actuator or a sensor:

If the system comes across a connection point with a "Digital input" signal type, for example, it will be considered an actuator.
If the connection point does not have one of the signal types listed above, the search continues to the connection points entered under Transfer potential to for that particular connection point. If no potential transfer is specified, the search ends here.
For connection symbols the transfer logic for the symbol is taken into consideration.
