FIELD: electricity.
SUBSTANCE: device (10) and method are proposed for electric energy transfer from circuit (12) of information exchange about processes in field busbar, at least to one other circuit (24) of information exchanges on processes, which operates in compliance with other protocol of data exchange on processes. Device (10) of energy transfer connects to circuit (12) of information exchange on processes in field busbar and to the second circuit (24) of information exchange on processes. Device (10) of energy transfer is fully supplied from circuit (12) of information exchange on processes in field busbar and is configured to supply at least some energy for the second circuit (12) of information exchange on processes.
EFFECT: reliability improvement.
