Function test device for a field device and method for testing the function of a field device and field device

摘要

Field device (1) of an emergency call system for a chemical plant, a gas burner or the like, and which an emergency - field device (1) a quick-action stop valve (4), a pneumatic actuator (5), the vented in the absence of the power supply, so that the quick-action stop valve (4) into a safety - or emergency operation position moves, and is a function test direction, with means for detecting the position of the quick-action stop valve (4), at least a volatile memory for storing the by the device to be detected quickly end of valve positions, at least one not - volatile memory for saving of the detected and stored in the volatile memory quickly end of valve positions, of a data processing device and at least one electrical energy damping device is provided which, in such a way to the means for detecting the rapidly end of valve positions, the data processing unit, the volatile memory and the not - volatile memory energy supply acts below that at least during the process of the quick-action stop valve (4) in the specific safety - or emergency operation position quickly end of valve positions are detected and be secured not - volatile and the data processing device quickly the secured connection valve positions in a new normal operating mode reads and evaluates.
