PROFINET Controller - Topology

Object: PROFINET Controller

This tab provides an overview of the topology of a PROFINET network and the neighborhood/peer information for each PROFINET device. The projected data is displayed on the left side, and the actual topology is retrieved and imported for a comparison on the right side. Deviating port interconnections are highlighted.

In order to read the topology information, a valid IP address must be set previously. See the Auto-IP command.

Note

Available only for devices with LLDP support (example: CC B) and all new devices according to the standard Profinet V2.3

This structure is checked every time the controller is switched on. The test leads to an error if it does not correspond to the actual wiring. Using this information, a defective device can be exchanged easily. In online mode, the actual structure is displayed in the right view.

Auto-IP

Automatically setting of a valid IP address within the network (network settings of the master) if the address scanned by the device is invalid.

<--

Accept/import the neighborhood information (online) of the selected devices in the project.

Reset

Resets the device settings of the selected device to default values

Blink LED

To identify a listed device by its hardware, select the device and click the Blink LED button. The device should respond by flashing.
