You have opened a project.
- You have selected a network / bus cable-connection point in the graphic editor. Edit > Properties. In the Properties <...> dialog, select the Bus data tab.
- You have selected a network / bus cable-connection point in the device navigator or in one of the PLC navigators. Popup menu item Properties or Properties (global). In the Properties <...> dialog, select the Bus data tab.
In this tab, you define the properties for the selected bus port that it has within a bus system.
In the Properties (global) processing mode, you edit the properties of all representations of the function jointly; in this case, the tab shows the supplement "(Device)".
Overview of the main dialog elements:
Here you enter the name of the configuration project for the currently selected bus port, or select an entry from the drop-down list.
The configuration project selected here may differ from the configuration project specified in the PLC box tab.
Enter the name of the physical network to which the bus port is connected. This name must be unique within the configuration project. Only one bus system can exist within a physical network.
Physical network: Bus ID / item number:
Enter the bus ID of the bus port here. Depending on the bus system, the value is a simple number, an IP address or a combination of letters and numbers.
Note:
You have the possibility to enter a further bus ID of the bus port in the Physical network: Bus ID / item number 2 property in the Properties of the network interface group box. The property is used for ASI devices during the PLC data exchange in the AutomationML format.
Enter the name of the logical network to which the bus port belongs. This entry has to be unique within a physical network.
Logical network: Bus port is master:
Activate this check box when the bus port represents the master of the logical network.
Select the type of bus system from the drop-down list, for example "PROFIBUS", "Ethernet", "ASI", etc.
Group box Properties of the network interface
The following properties are available, among others, for bus ports:
- Bus interface: Name: The bus interface name serves to group bus ports for the export of Ethernet-based bus systems. Associated bus ports are combined into a logical unit via this name. These can be either bus ports of the type "Network / bus cable connection, general" or a "Network / bus cable connection, input" and a "Network / bus cable connection, output".
The bus interface name is used together with the plug designation for identifying bus ports. - Bus interface: Main bus port: Identifies a bus port within an interface as the main bus port. This bus port represents the bus interface and bears the data relevant for the data exchange (among others Physical network: Bus ID / item number, MasterSystemId). During exporting the data are read from the main bus port and written into the PLC configuration file.
Exactly one main bus port must exist within an interface. This is either the bus port "Network / bus cable connection point, input" or one of the bus ports of the type "Network / bus cable connection point, general". - Ignore missing bus ID: This setting is provided for devices in bus systems that do not require a bus ID. If this property is activated at a bus port, the missing bus ID is ignored during the execution of check run 004037, and no check run message is issued for this bus port.
