ABSTRACT:
A display for on-site visualization of conditions of an automated process is disclosed. It comprises a display controller which at least temporarily provides a state indication signal representing a constellation of states of at least two process data signals. At least one of the two process data signals is derived from a signal generated externally to the field device. The field device has a display element which responds to a change in the state indication signal with a significant change in its appearance, thus signaling the constellation of the states of the two process data signals in a visually perceptible manner. Therefore, the field device is particularly suited for on-site monitoring of entire plants or sections thereof by operating personnel.
