CMS 3.0 is an InControl product. The operator terminal is based on a Pro-face TFT touch MMI (Man Machine Interface). The PLC is Allen Bradley based. The MMI displays all relevant information for the operator on the Main Screen. The top and bottom fields of the screens are standard for all screens and contain important real-time information. Buttons for screen navigation are incorporated in the bottom. The bar graphs visualize the numeric displays and adjust real-time to the movement of the Jib and the current Load Chart.
