Operator Control and Monitoring DevicesPush Button PanelsSIMATIC PP72■ OverviewSIMATIC Push Button Panels are the innovative alternativeto conventional operator panels for easy and direct control ofmachines:• Pre-fabricated and ready for operation;simply connect to the control and all buttons and lamps areready for immediate use• Connection to any type of control via a bus cable(PROFIBUS DP as "standard slave" or MPI)• Fitted with short-stroke keys, additional digital inputs and slotsfor 22.5 mm standard components■ Benefits• Up to 90% time savings: Pushbuttons, switches and lampsdo not have to be fitted and wired individually• Use of standard cables, for example, makes configuration andstartup easier• No configuration tool required• Service-friendly thanks to rear display to indicate operatingstates and messages in plain text, without programmingdevice• Quick and easy machine operation thanks to multi-coloredindicator lights• User-friendly labeling option for pushbuttons and lamps usingslide-in labels• As the 22.5 mm standard elements can be connected directlyon the panel, no additional wiring and I/O modules arerequired.■ DesignThe push button panels impress customers with their compactdesign:• Factory-fitted with 8 short-stroke keys, that can be labeled asrequired using insertable strips• Smooth front that is easy to clean;the front is resistant to various oils, greases and standarddetergents• Long-life, multi-color, surface-lighting LEDs in all short-strokekeys• Additional digital inputs for flexible expansions• Pre-perforated cutouts for additional standard 22.5 mm components(pushbuttons, lamps, emergency stop pushbuttons,key switches)• Rear display with mini-keypad to display operating states andin plain text for changing the default settings• The PP7 is designed to match the OP7 and they can thereforebe mounted side by side• Low-maintenance because batteries are not required• All parameters are located in a memory module that can easilybe replaced■ Function• LED color modes (e.g., red, green, orange, red-flashing,green-flashing, yellow-flashing)• Integrated flashing rate for LED• Integrated diagnostic functions• Integrated lamp and key test (also for additional digital inputs)• Menu-assisted parameterization via rear display with miniaturekeyboard• Short-stroke keys and digital inputs are also parameterizableas switches• Parameterizable pulse stretching for short-stroke keys anddigital inputs• PROFIBUS DP standard slave■ ApplicationThe rugged PP7 Push Button Panel is designed for simple andstraightforward machine operation.It can be used wherever HMI functions cannot be carried outwithout keys and lamps, e.g. on control consoles for machinesand plants in the food and beverage industry where smoothfronts are necessary to facilitate cleaning. Even in special mechanicalequipment manufacture, the push button panels canbe used to easily set up standard operator panels that are thenamenable to fast, flexible and modular expansion. The key andlamp functions can be changed later at any time without havingto modify the wiring.2/8Siemens ST 80 · 2006
