Procedure for monitoring a system (A) used in automation engineering, wherein said system has a fieldbus access unit (FE), particularly a computing unit, a gateway or an edge device, wherein said fieldbus access unit (FE) has a communication connection to at least a first wired or wireless communication network (KN1), wherein the first communication network (KN1) has multiple field devices (F1, F2, F3, ..., FN) and network nodes (NK1, NK2, NK3, ..., NKm), wherein a communication driver (KT) - which runs in a first framework application (FR1), wherein said first framework application (FR1) is implemented on a client computer (CR) connected directly or indirectly to the fieldbus access unit (FE) via at least a second communication network (KN2) - retrieves structure data of network nodes (NK1, NK2, NK3, ..., NKm) and field devices (F1, F2, F3, ..., FN) present in at least one network level (NE1, NE2) of the first communication network (KN1), wherein the retrieval of the structure data is transmitted to the fieldbus access unit (FE) and the latter unit creates said structure data and transmits the data to the client computer (CR); and wherein, within the framework of the data retrieval, the structure data is created by the fieldbus access unit (FE) in that the fieldbus access unit (FE) scans the address space of the network level (NE1, NE2) and determines the network nodes (NK1, NK2, NK3, ..., NKm) and field devices (F1, F2, F3, ..., FN) present in the address space, wherein the structure data concerns the infrastructure of the first communication network and contains network addresses and identification data of the determined field devices (F1, F2, F3, ..., FN) and network nodes (NK1, NK2, NK3, ..., NKm), as well as the network level (NE1, NE2) in which the determined field devices (F1, F2, F3, ..., FN) and network nodes (NK1, NK2, NK3, ..., NKm) are determined. wherein a communication driver (KT) - which runs in a first framework application (FR1), wherein said first framework application (FR1) is implemented on a client computer (CR) connected directly or indirectly to the fieldbus access unit (FE) via at least a second communication network (KN2) - retrieves structure data of network nodes (NK1, NK2, NK3, ..., NKm) and field devices (F1, F2, F3, ..., FN) present in at least one network level (NE1, NE2) of the first communication network (KN1), wherein the retrieval of the structure data is transmitted to the fieldbus access unit (FE) and the latter unit creates said structure data and transmits the data to the client computer (CR); and wherein, within the framework of the data retrieval, the structure data is created by the fieldbus access unit (FE) in that the fieldbus access unit (FE) scans the address space of the network level (NE1, NE2) and determines the network nodes (NK1, NK2, NK3, ..., NKm) and field devices (F1, F2, F3, ..., FN) present in the address space, wherein the structure data concerns the infrastructure of the first communication network and contains network addresses and identification data of the determined field devices (F1, F2, F3, ..., FN) and network nodes (NK1, NK2, NK3, ..., NKm), as well as the network level (NE1, NE2) in which the determined field devices (F1, F2, F3, ..., FN) and network nodes (NK1, NK2, NK3, ..., NKm) are determined. <EOS>
