| 摘要 |
The invention relates to a system, particularly a process automation system, consisting of at least one control technique (1) and several sensors (5.1...5.n) communicating with said control technique, especially proximity sensors. The invention is characterised in that said sensors (5.1 ...5.n) are respectively provided with at least one display device (6.1...6.n),particularly a luminous diode. The display devices (6.1...6.n) of the sensors (5.1...5.n) are activated by the control technique according to requirements. |
