Method for operating an ethernet-capable field-bus device
First Claim
1. Method for operating an Ethernet-capable field-bus device (50) within an automation system, wherein this field-bus device is connected to an Ethernet-based communications network (20) by means of which user data is transmitted using a predetermined communications protocol stack with the following processing steps:
- a) establishing a network management channel between the Ethernet-capable field-bus device (50) and a management device (30) connected to the communications network (20) using an Ethernet-based network management protocol that is installed both in the field-bus device (50) and also in the management device (30),b) transmitting the communications protocol stack using the predetermined network management protocol from the management device (30) to the Ethernet-capable field-bus device (50),c) storing and installing the predetermined communications protocol stack in the Ethernet-capable field-bus device (50, 55), wherein the communications protocol stack controls a transmission of user data via the Ethernet-based communications network (20).

Abstract
The invention relates to a method for operating an Ethernet-capable field-bus device that can be connected to an arbitrary Ethernet-based communications unit by means of which data is transmitted using a predetermined communications protocol stack. For this purpose, a network management channel is initially established between the Ethernet-capable field-bus device (50) and a management device (30) connected to the communications network (20) using an Ethernet-based network management protocol that is installed both in the field-bus device (50) and also in the management device (30). The communications protocol stack installed in the management device (20) is then transmitted using the predetermined network management protocol from the management device (30) to the Ethernet-capable field-bus device (50), where it is stored. In this way, it is guaranteed that useful data can be transmitted using the communications protocol stack from and to the field-bus device (50) via the Ethernet-based communications network (20).
