Field detection device for a fieldbus network

A field detection device which is designed to be connected to at least one access point of a fieldbus network via at least one interface,

• wherein the field detection device is designed to initiate or execute, for each of at least two connection protocols, an associated query in at least one fieldbus segment of the fieldbus network and to detect which field devices and fieldbus components in said at least one fieldbus segment can be accessed by means of the connection protocol in question, and
• wherein the field detection device is further designed to provide a connection directory in which at least one connection protocol is specified for each field device and for each fieldbus component of a set of field devices and fieldbus components of the at least one fieldbus segment by means of which connection protocol the field device in question or the fieldbus component in question can be accessed.

A fieldbus network comprising at least one field detection device which is designed to be connected to at least one access point of a fieldbus network via at least one interface,

• wherein the field detection device is designed to initiate or execute, for each of at least two connection protocols, an associated query in at least one fieldbus segment of the fieldbus network and to detect which field devices and fieldbus components in said at least one fieldbus segment can be accessed by means of the connection protocol in question, and
• wherein the field detection device is further designed to provide a connection directory in which at least one connection protocol is specified for each field device and for each fieldbus component of a set of field devices and fieldbus components of the at least one fieldbus segment by means of which connection protocol the field device in question or the fieldbus component in question can be accessed.

A method for creating a connection directory for a fieldbus network, the method comprising:

• for at least two connection protocols, in each case initiating or executing an associated query in at least one fieldbus segment of the fieldbus network and detecting which field devices and fieldbus components in the at least one fieldbus segment can be accessed by means of the connection protocol in question;
• providing a connection directory in which at least one connection protocol is specified in each case for each field device and for each fieldbus component of a set of field devices and fieldbus components of the at least one fieldbus segment, by means of which connection protocol the field device in question or the fieldbus component in question can be accessed.
