SIMATIC Mobile Panel 177 DP

6 Inch Handheld Panel with color display and combined touch and key operation


Windows CE based handheld-panel for "on site" operation of machinery and systems. Combined operation by touch screen and keys. Mobile Panels 177 DP are available in three versions for operation within a PROFIBUS network.

Area of application

Regardless of the industry or application, if mobility is required for the on-site control and monitoring of machines and plants, SIMATIC Mobile Panels offer some crucial advantages: The machine operators or commissioning engineers are able to work exactly where they have the best view of the workpiece or process. Even for larger production facilities, complex or enclosed machines, long materials handling or production lines and conveyor systems, mobile operator panels allow fast and precise setting up and positioning during commissioning. They also ensure shorter downtimes during retooling, maintenance or repairs.


  • Reliable operation with perfected safety concept

  • Ergonomic, compact and light-weight

  • Rugged for industrial use

  • Can be used worldwide with 32 configurable languages
    (of which 16 are online-switchable)

Design and functions

The Mobile Panel 177 DP is offered in three device variants that differ in the number of control elements:
While device variant 1 is operated by a touch screen, 14 function keys and an enabling button, device variant 2 offers  an additional STOP-button (EN 60204-1) 2 channel, forced blocking that can be wired into emergency stop circuit.
Device variant 3 offers the stop-button, a keyswitch with 3 switch settings, an illuminated push-button and a handwheel.

The mobile panel is simply plugged into the connection box wherever it is needed on the machine and is immediately ready for use. The rugged and safe connection box with IP65 protection can be mounted anywhere, even outside the control cabinet. It ensures fault-free hot swapping and thereby creates the opportunity of switching the operating locations simply and safely if there are several connection points in one plant or machine.
The SIMATIC Mobile Panel can be configured such that the user interface changes according to the connection point.The connection point recognition enables machine-specific HMI calculations or actions to be performed depending on the selected connection point.

Device models with an additional STOP pushbutton can be wired into the emergency shutdown circuit of a machine or plant by means of the connection boxes. In this way, the STOP pushbutton offers the functionality of an emergency stop pushbutton, but differs visually from conventional emergency stop devices due to its gray color. This eliminates any danger of confusion. This is important first and foremost because the mobile operator panel - contrary to the requirement for emergency stop devices - is not always connected to the machine. STOP and enabling pushbuttons are designed with dual circuits according to the safety regulations (EN 60204-1). This means it is possible to achieve Safety Category 3 to EN 954-

The communication with the PLC is implemented via PROFIBUS DP at up to 12 Mbit/s, via MPI or via the serial interface.The connecting cable can be up to 25 meters long.The interfaces are already integrated and a variety of drivers –even for non-Siemens PLCs – are also included. DP devices can only be connected to PROFIBUS connection boxes.

Security information

To ensure the secure operation of a plant or machine it is also necessary to take suitable preventive action (e.g. cell protection concept) and to integrate the automation and drive components into a state-of-the-art holistic industrial security concept for the entire plant or machine. Any third-party products that may be in use must also be taken into account. Please find further information at:
