FIELD: automation of processes with usage of field devices. ^ SUBSTANCE: method is realized in control device by means of operation program, which for parameterization in dialog mode is connected to field device via data transfer bus, and which has no access to device description, which describes behavior of field device in autonomous mode. Technical result is achieved because operation program connects to copy of software program of device executed in field device, realizing imitation of field device in dialog mode. ^ EFFECT: simplification and lower costs of programming. ^ 8 cl, 3 dwg
