The Simatic Step 7 Topology Editor from Siemens Automation and Drives (A and D) represents Profinet infrastructures in the Step 7 engineering system.
The Simatic Step 7 Topology Editor from Siemens Automation and Drives (A and D) represents Profinet infrastructures in the Step 7 engineering system.
This simplifies the startup of Profinet networks, enables comprehensive diagnostics of all components during operation, and supports plant documentation.
The integration of Topology Editor into Step 7 means that the status of the network infrastructure is now viewable online.
Until now, this has only been the case for the automation components.
The network components use the communication mechanisms LLDP (Link Layer Discovery Protocol) in accordance with IEEE802.1ab and SNMP (Simple Network Management Protocol).
Each Profinet device uses LLDP to identify the neighbors on its ports autonomously.
Step 7 scans the neighborhood relationships via SNMP and represents the topology of the Profinet infrastructure either graphically or in the form of a table - online or offline.
