A system and method for operating measuring devices in a process plant includes providing at least one measuring device for detecting at least one measuring variable, the measuring device having comprises at least one memory means for storing actual configuration data; providing at least one controller unit having at least one additional memory means in which projected configuration data is stored; the controller unit does not have write access to the measuring device with respect to the actual configuration data; and wherein the at least one measuring device and the at least one controller unit are connected via at least one network; comparing the actual configuration data and the projected configuration data, and when the configuration data correspond, allowing a data communication.

Operation of measuring devices in a process plant

Exemplary embodiments are directed to a system and method for integrating field devices in an automation system having a plurality of field devices connectable via at least one bus system. A respective field device is connected to the bus system of the automation system, and is automatically addressed by a superordinate controller using a predefined default address. The device addressed using the default address then registers in the system with its device address, and a fixed address which is provided from a multiplicity of unassigned addresses from an address memory is automatically allocated to the device registered in the system. An individually assigned identification (TAG) provided from the predetermined configuration of the automation system is allocated to the allocated fixed address, and, after the automatically allocated fixed address has been transmitted to the field device, the field device is changed to a suitable state for communication with the superordinate controller.
