• Integrated serial, MPI/PROFIBUS (up to 12 Mbps) and/or PROFINET interface (up to 100 Mbps)

or

• Connection to the PLC via rugged and reliable connection boxes with degree of protection IP65:
  • "Basic" connection box: Enables the STOP button to be integrated into the safety circuit
  • "Plus" connection box: Enables the STOP button to be integrated into the safety circuit without interruption when disconnecting the device. The emergency stop circuit remains closed regardless of whether a Mobile Panel is plugged in or not. If the Mobile Panel is disconnected during operation, the emergency stop circuit in the connection box Plus is automatically closed which prevents triggering of the emergency stop circuit.
• Fast system availability after plugging into the connection box
  • An optional rechargeable battery pack can be used to avoid restarting of the Mobile Panel (following brief disconnection from the connection box).
• Detection of the connection point can be used to perform machine-specific HMI authorizations or actions depending on the selected connection point

Advanced safety concept

The two acknowledgement buttons (acc. to EN 60204-1) with three switching steps each ensure the protection of personnel and machines in critical situations. They are integrated into the handle on the back.

The STOP button (acc. to EN 60204-1) is hard-wired and positively latches when pressed. It can be looped into the emergency-stop circuit of a plant in which case it takes on the functionality of an emergency stop button, but is distinct with its gray color. This ensures that it cannot be mistaken for the emergency stop equipment. This is especially important when the Mobile Panel is not connected to the machine. SIMATIC Mobile Panels offer the option of making safety functions available on a mobile basis at any point of a machine or plant.

STOP and acknowledgement buttons are implemented according to safety regulations with two circuits and comply with the requirements of Category 3 PLd according to DIN EN ISO 13849-1:2008.

Innovative connection concept

The Mobile Panel is simply plugged into the connection box wherever it is needed in the plant and is immediately ready for use. The connection box can be installed anywhere, even outside the control cabinet. It ensures fault-free plugging and unplugging during normal operation and, therefore, allows the operator-control location to be easily and safely changed when several connection points are available in a plant or machine.

The location of a Mobile Panel can be clearly identified by setting an ID number on the connection box. This identifier permits the user to configure Mobile Panels in such a way that, for example, the user interface changes according to the connection point. The Mobile Panel establishes the connection to the controllers after being plugged into the connection boxes and following a short start-up period. An optional rechargeable battery pack can be used to avoid restarting of the Mobile Panel (following brief disconnection from the connection box).

Configuration possibilities with emergency stop loop-in

Device versions with STOP button can be wired into the emergency stop circuit of a machine or plant by means of the connection boxes. When the STOP button on the Mobile Panel is pressed, the emergency stop function is activated. The STOP button on the Mobile Panel supplements, but does not replace, the emergency stop equipment installed on the machine. When the Mobile Panel is unplugged, "Plus" versions of the connection box automatically close the emergency stop circuit, thereby ensuring safe and fault-free changeover (swapping).

Connection at one point on the machine

When the "Basic" connection box variant is used, unplugging the Mobile Panel interrupts the emergency stop circuit and, therefore, triggers the emergency stop function. This configuration is, therefore, best suited for applications in which the Mobile Panel is connected to a fixed point on the machine (example configuration: Mobile Panel 177).

Variable connection at different points of a machine or plant

If a Mobile Panel with a STOP button is used in combination with a "Plus" connection box, a configuration is possible in which the Mobile Panel can be used flexibly and is also looped into the emergency stop circuit. The emergency stop circuit remains closed regardless of whether a Mobile Panel is plugged into a connection box or not. When the Mobile Panel is plugged in, the equipment is looped into the emergency stop circuit and when the STOP button is pressed, the circuit will be interrupted and the emergency stop function triggered. If the Mobile Panel is unplugged during operation, the emergency stop circuit is automatically closed in the "Plus" connection box version (example configuration: Mobile Panel 177).

Mobile operator control and monitoring in the Industrial Wireless LAN

The SIMATIC Mobile Panel 277(F) IWLAN enables integration as a WLAN client in wireless LAN networks. This makes it possible to implement a full-fledged mobile HMI device, which can also perform tasks that are not possible with stationary or cabled devices.

Reliable and rugged WLAN networks can be created using SCALANCE W IWLAN access points. The configuration and simulation software SINEMA E permits reliable WLAN planning ahead of time.

The device is configured – just like the cabled Mobile Panels – with WinCC flexible. The compatibility and continuity permit easy and problem-free migration of existing projects to the wireless device.

Transponders have been developed especially for the Mobile Panel 277(F) IWLAN and can be used for the local identification of the Mobile Panel in the plant. Comparable with the connection point recognition (Box-ID) for cabled Mobile Panels, these transponders can be used to configure location-dependent functions, e.g. the automatic switchover to a different display when a certain zone is accessed, or releasing/blocking of functions from the control zone. On the fail-safe Mobile Panel with enable button and emergency stop button (Mobile Panel 277F IWLAN), the transponders perform another task: The safety-related release of the enable button for hazardous operations. Alternatively, the Mobile Panel 277F IWLAN (RFID Tag, MOBY D) for already delineated safety zones, such as robot cells, can be used. The monitoring of the protection areas is assumed by the alternative measures, not by the RFID Tag.

Full safety functionality - even wireless!

The SIMATIC Mobile Panel 277F IWLAN is integrated via PROFINET and PROFIsafe into the safety-oriented program (Distributed Safety) of a SIMATIC F-CPU. Incorporating and removing Mobile Panels is possible during runtime. Both of the safety-related functions "acknowledgement button" and "emergency stop button" comply with SIL 3 according to IEC 61508 or PLe/Cat. 4 according to DIN EN ISO 13849-1 and are TUV-certified. A detailed safety manual is delivered with the Mobile Panel 277F IWLAN, along with a CD containing the required F function blocks for integration in the F-program. The F-FBs are tested and certified - this enables a problem-free and simple integration of the Mobile Panel.

The emergency stop button is immediately available WLAN-wide as soon as the Mobile Panel 277F IWLAN is booted up and the PROFISAFE connection is established with the F-CPU via IWLAN. To use the acknowledgment button locally, transponders or RFID tags must be installed in the intended control stations. This allows the Mobile Panel to register for safety-related operation. Configuration of the transponder and the effective range is also handled comfortably with WinCC flexible. After configuration and commissioning, the effective range in the system is approved to ensure the consistency of the planning and configuration. The effect that the emergency stop button and the acknowledgment button should have and which response to certain events (e.g. leaving the WLAN range) they should have is defined by configuring the F-FBs in the F-CPU – taking account of the safety-relevant properties of the machine. If the Mobile Panel is not used any longer or if the device should be removed, it is to be moved to a specified location.

The Mobile Panel 277F IWLAN offers extensive diagnostic and status information (e.g. concerning the battery charge status, WLAN functionality, and quality of the effective range) and thus provides the user – if necessary, supported by the integrated vibration alarm – with full control of the device and system operation at all times.
