A processing plant comprises a control system to control and monitor operation of the machine elements of the plant. The control system comprises a plurality of detecting means each positioned proximate to one of the machine elements of the plant, and which is operative to generate an output signal representative of the condition of operation of the machine element, and to feed such output signal to a central processing unit. In turn, the central processing unit generates an audible output signal which is representative of the sound generated by the machine element during operation thereof, enabling a controller supervising operation of the plant to "hear" the way in which the machine elements are performing. <IMAGE> |
