Operator Control and Monitoring DevicesMobile panels - 170 seriesSIMATIC Mobile Panel 177■ Design• Ergonomic and compact with different holding and grippingpoints (suitable for right-handed and left-handed personnel)• Pixel graphics, brilliant 5.7" color STN display with 256 colorsand touch screen (analog/resistive)• 14 user-configurable and user-inscribable function keys(8 with LED)• The front is resistant to various oils, greases and standarddetergents• Two three-stage enabling buttons• Optional variants with- STOP pushbutton or- STOP pushbutton, handwheel, key-operated switch andilluminated pushbutton- The STOP pushbutton is secured specifically with a"protective collar".If the STOP pushbutton is looped into the emergency-stopcircuit, its function is equivalent to an emergency stop.• Extreme impact resistance thanks to the double-wall constructionand rounded casing.(The Mobile Panel will withstand a fall from a height of 1.5 mwithout sustaining any damage.)• Dust-proof and jet-proof casing with degree of protection IP65on all sides• Integrated serial, MPI and PROFIBUS interface(up to 12 Mbit/s) for the Mobile Panel 177 DPOr• Integral Ethernet (PROFINET) interface (up to 100 Mbit/s)with the Mobile Panel 177 PN• Slot for a standard Multi Media Card (MMC) for backup andrestoration or for storing recipes• Connection to the PLC via the rugged and reliable junctionboxes with IP65 degree of protection:- “Basic“ junction box: Enables the STOP pushbutton to beintegrated into the safety circuit- "Plus" junction box: Enables the STOP pushbutton to beintegrated into the safety circuit.The emergency stop circuit is not interrupted even if theMobile Panel is unplugged. If the Mobile Panel is disconnectedduring operation, the emergency stop circuit in thejunction box Plus is automatically closed which preventstriggering of the emergency stop circuit.• Fast system availability after plugging into the junction boxes- An optional rechargeable battery pack can be used to speedup the Mobile Panel connection process (following a briefperiod of disconnection from the junction box) still further.• Detection of the connection point can be used to performmachine-specific HMI authorizations or actions depending onthe selected connection pointSophisticated safety conceptThe two enabling buttons (acc. to EN 60204-1) with three switchingsteps each ensure the protection of personnel and machinesin critical situations. They are built into the rear handle.The STOP pushbutton (acc. to EN 60204-1) is hard-wired andpositively latches when pressed. It can be looped into theemergency-stop circuit of a plant in which case it takes on thefunctionality of an emergency stop pushbutton, but is distinctwith its gray color. This ensures that it cannot be mistaken for theemergency stop equipment. This is especially important whenthe Mobile Panel is not connected to the machine. SIMATICMobile Panels offer the option of making safety functions availableon a mobile basis at any point of a machine or plant.STOP pushbuttons and enabling buttons are implemented accordingto safety regulations with two circuits and comply withthe requirements of Safety Category 3 according to EN 954-1.Innovative connection conceptThe Mobile Panel is simply plugged into the connection boxwherever it is needed in the plant and is immediately ready foruse. The junction box can be installed anywhere, even outsidethe control cabinet. It ensures fault-free plugging and unpluggingduring normal operation and, therefore, allows the operatorcontrollocation to be easily and safely changed when severalconnection points are available in a plant or machine.The location of a Mobile Panel can be clearly identified by settingan ID number on the junction box. This identifier permits theuser to configure Mobile Panels in such a way that, for example,the user interface changes according to the connection point.The Mobile Panel 177 establishes the connection to the controllersafter being plugged into the junction boxes and following ashort running-up period. An optional rechargeable battery packcan be used to speed up the Mobile Panel connection process(following a brief period of disconnection from the junction box)still further.Any existing Mobile Panel 170 junction boxes can be used inconjunction with the Mobile Panel 177 because they are fullycompatible. The new function of connection-point detection canonly be used in conjunction with a Mobile Panel 177 with a DP orPN junction box. A Mobile Panel 177 DP (PROFIBUS) cannot beconnected to a PN (PROFINET) junction box and vice versa andis mechanically blocked.Configuration options with emergency stop wiringPanels with a STOP pushbutton can be integrated into the emergencystop circuit of a machine or plant via the junction box.When the STOP pushbutton on the Mobile Panel is pressed, theemergency stop function is activated. The STOP pushbutton onthe Mobile Panel supplements but does not replace the emergencystop equipment installed on the machine according toEN 418. When the Mobile Panel is unplugged, "Plus" versions ofthe junction box automatically close the emergency stop circuit,thereby ensuring safe and fault-free changeover (swapping).2Siemens ST 80 · 2006 2/35
