ABSTRACT:
A display (AV) for on-site visualization of conditions of an automated process (PZ) is disclosed. It comprises a display controller (AS) which at least temporarily provides a state indication signal (ZA) representing a constellation of states of at least two process data signals (PD1, PD2). At least one of the two process data signals (PD1, PD2) is derived from a signal (RX) generated externally to the field device (F1). The field device (F1) has a display element (AE) which responds to a change in the state indication signal (ZA) with a significant change in its appearance, thus signaling the constellation of the states of the two process data signals (PD1, PD2) in a visually perceptible manner. Therefore, the field device (F1) is particularly suited for on-site monitoring of entire plants or sections thereof by operating personnel.
