<p>#CMT# #/CMT# The method involves transmitting apparatus identification data e.g. manufacturer, by a slave (2) in a field bus system to a master component (1) in the bus system in an inactive state of the slave, where the bus system conforms to actuator sensor (AS) interfacestandard. An apparatus of the slave is identified based on the transmitted identification data, and data exchanging telegram is transmitted by the master component to the slave during the inactive state, where the telegram contains utilizable data for extended data communication from the master component to the slave. #CMT# : #/CMT# An independent claim is also included for a master component for receiving apparatus identification data. #CMT#USE : #/CMT# Method for identifying an apparatus i.e. field device component, of a slave in a field bus system (all claimed) of an automation system that is utilized for connecting the apparatus with a control device. Uses include but are not limited to digital or analog input and output modules, motor initiators, frequency changers, sensors, actuators and drives. #CMT#ADVANTAGE : #/CMT# The apparatus identification data is transmitted by the slave in the field bus system to the master component in the bus system in the inactive state of the slave, thus identifying the apparatus of the slave based on the transmitted identification data in an accurate manner even in the inactive state of the slave. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a master component connected with a set of slaves over a bus cable. 1 : Master component 2 : Slave 3 : Bus cable.</p> |
