SYSTEM FOR CABLING THE AUTOMATION EQUIPMENT AND CONTROL EQUIPMENT OF A TECHNICAL PLANT

摘要

The invention relates to a system for cabling intelligent field devices (41, 42, 43) and/or input/output units (44, 45, 46) to primary control equipment (1) of a process control system of the technical plant by means of at least two automation devices (21, 22, 23), which are connected to the primary control equipment (1) by means of a system bus (10). The automation devices (21, 22, 23) are connected to the intelligent field devices (41, 42, 43) and/or input/output units (44, 45, 46) by means of an Ethernet bus system (50) in such a way that a signal transfer between the field devices (41, 42, 43) and/or input/output units (44, 45, 46) and the automation devices can be carried out by means of the Ethernet bus system (50).
