METHOD AND SYSTEM FOR STARTING UP FIELD DEVICES, IN PARTICULAR HART FIELD DEVICES IN THE MULTIDROP MODE OF OPERATION
The invention relates to a system (SB) for starting up field devices (F1 -F4), wherein said system can be connected to a voltage supply (PS), wherein the voltage supply (PS) is used to supply the field devices (F1 -F4) with electrical power, wherein the system (SB) comprises at least one starter circuit (S1), said starter circuit (S1) being used to disconnect at least one field device (F2) following a preceding one of the field devices (F1) according to a predetermined sequence of field devices (F1 -F4) from the voltage supply (PS) at least until the preceding field device (F1) receives a substantially constant current which is used to operate the preceding field device (F1) in a specific mode of operation.
