Patent ID: 8798930

Claim:
A method for servicing a multi-channel field device of process automation technology, wherein: the field device comprises a measurement transmitter and has at least two measurement channels, an external service unit; each measurement channel has a sensor for registering a process variable and a program module running in a microcontroller for measured value processing, and, for connection to a fieldbus, a single fieldbus interface, which is connected with said microcontroller; a communication between said sensors and said microcontroller occurs digitally via an RS485-connection; and said fieldbus interface has at least two communication controllers which have different fieldbus addresses, the method comprising the steps of: providing in the service unit, separate device descriptions for the measurement channels; and invoking the individual measurement channels in the service unit via the corresponding device descriptions as logical units, so that, in the servicing, the field device appears to the user as at least two logically independent field devices.
