FIELD: technology for automation and control over processes, for adjusting electric power of several field devices. ^ SUBSTANCE: in the method for adjusting electric powering of several field devices S1,S2,S3,A1,A2, connected by DBL data bus line and powered through DBL data bus line by electric power, need of several field devices S1,S2,S3,A1,A2 in electric energy and electric energy consumption by field devices field devices S1,S2,S3,A1,A2 are set by means of appropriate controlling signals. Due to that consumption of energy by separate field devices S1,S2,S3,A1,A2 can be centrally set and, thus, synchronized with conditions of process. ^ EFFECT: simple and efficient setting of energy flow values by separate field devices. ^ 4 cl, 2 dwg |
