Engineering via the PROFINET interface

In principle, engineering is possible via the PROFINET interface. Engineering via the PROFINET interface is subject to the following limitations:

• Speed
• The PROFINET interface is designed for process data synchronicity and reliability. The PROFINET interface is not optimized for transmission of large amounts of data, such as IEC projects.
• IP stack
• The IP stack is part of the IEC project. If an IEC project is loaded without fieldbus stations, a connection to the device via the PROFINET interface is no longer possible.
• IP address
• The initial IP address is specified in the IEC project. When communication via the PROFINET interface is started, the IP address is rewritten by the PROFINET controller. A connection via the initial PROFINET interface is then no longer possible.

INFORMATION

SEW‑EURODRIVE recommends using the standard engineering interface for startup.

As soon as the project on the controller has reached a stable state, e.g. when regular updates and downloads of the IEC project are no longer required, the PROFINET interface can be used for engineering. If already known, assign the correct IP address in the IEC project in the properties of the fieldbus station.
