Integration of field devices in a distributed system

摘要

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.

1. A method for automatically integrating field devices in an automation system having a plurality of field devices connectable via at least one bus system, the field devices being incorporated in the automation system via the bus system according to a predetermined configuration stored in memory of the automation system and executed by a processor of the automation system, the method comprising:
connecting a respective field device to the bus system of the automation system; automatically addressing the respective field device connected to the system by a superordinate controller using a predefined default address by means of an automatically running first routine; registering the default address of the addressed device in the system using its device address; allocating automatically a fixed address selected from a plurality of unassigned addresses in an address memory to the device registered in the system by means of a second automatically running routine; allocating an individually assigned identification (TAG) provided from a predetermined configuration of the automation system to the allocated fixed address; and after the automatically allocated fixed address has been transmitted to the respective field device, changing the field device to a suitable state for communication with the superordinate controller.
