The bus structures required for a PLC configuration data exchange are taken solely from the single-line connection information of the bus. Multi-line representation of the bus is not required. Detailed multi-line representations of standard bus cables can be implemented by means of a cable assignment diagram.
In the parts management the network / bus cable-connection points (in brief: bus ports) and the PLC connection points of a PLC card are represented as function templates. A bus port represents a plug and is represented by only one function template. If you want to place the bus ports in single-line and the remaining PLC connection points in multi-line, this can be achieved by using part macros that contain a single-line and a multi-line variant.
Either a plug designation (and in addition, if necessary, the bus interface name) or a connection point designation must be entered at the single-line bus port so that the function templates in the PLC navigator are overlapped correctly.
If required, you can place the single-line bus port additionally with the "Multi-line" representation type.
Multi-line representation all the contacts of a bus port
If it should be necessary to represent a bus cable with all the individual contacts in multi-line, you can increase the number of connection points at the bus port and place a symbol suitable for the set number of connection points.
Preconditions:
- You have opened a page in the graphical editor.
- You have opened the PLC navigator.
- Select the following menu items: Insert > Box / connection point / mounting panel > Bus port
- Place the bus port on the project page.
- Check that the bus port has the representation type "single-line" in the Symbol / function data of the property dialog.
- Enter the number of connection points, meaning the number of contacts of the network / bus cable-connection point, in the Connection points field.
- Click [OK].
- Mark the bus port in the PLC navigator and select the popup menu Place.
- Press the [Backspace] and select a symbol for the bus port with the corresponding number of connection points.
- Confirm your entries.
- Place the symbol on the project side. If applicable change the representation type to "Multi-line".
In the PLC navigator a multi-line and a single-line bus port is displayed, whose data are synchronized with each other and that consequently overlap the function template together.
Note:
The multi-line bus port should only be placed once with all its contacts in a symbol. This is the only means of ensuring complete editing and correct overlapping of the function templates.
