6.11.1 Overview of network operation

Introduction

You connect the HMI device to a PROFINET network.
The connection to a network offers, for example, the following options:

● Printing via a network printer

● Saving, exporting and importing of recipe data records on or from a server

● Setting up of message and data archives

● Transferring a project

Addressing

● Saving data

NOTICE

The HMI device can only be used in PROFINET networks.
The HMI device only has client functionality in the PC network. This means that users

can access files of a node with TCP/IP server functionality from the HMI device via the
network. However, you cannot, for example, access data on the HMI device from a PC
via the network.

Note
Information on communication using SIMATIC S7 via PROFINET is provided in the

"WinCC flexible communication" user manual.

Within a PROFINET network, computers are usually addressed using device names. These
device names are translated from a DNS or WINS server to TCP/IP addresses.

The corresponding servers are generally available in PROFINET networks.

Note
The use of TCP/IP addresses to address PCs is not supported by the HMI device's operating

system.
So to address the HMI device using device names in a PROFINET network, you need a

DNS or WINS server.

Consult your network administrator if you have questions in this regard

7.5.3 Testing a project

Introduction

There are two options to test a project:

● Test the project on the configuring PC
You can test a project at a configuring PC, using a simulator. For detailed information,

refer to the "WinCC flexible" user manual and to the WinCC flexible online help.

● Offline testing of the project on the HMI device
Offline testing means that communication between the HMI device and PLC connections,

which have been configured in WinCC flexible, is down while the test is being carried out.
The PROFIsafe connection between the HMI device and PLC is also available in "Offline"
mode.

● Online testing of the project on the HMI device
Online testing means that the HMI device and PLC communicate with each other during

testing.

Perform the tests, starting with the "Offline test", followed by the "Online test".

Note
You should always test the project on the HMI device on which the project will be used.

Check the following:

1. WLAN coverage

2. Zone recognition, if zones have been configured

3. Check the correct layout of the screens

4. Check the screen navigation

5. Check the input objects

6. Enter the tag values

The test increases the certainty that the project will run error-free on the HMI device.

7.5.4 Acceptance of the system

7.5.4.1 Overview

Introduction

The acceptance of the system includes the following areas:

● Configuring the F CPU and fail-safe I/O

● Safety program

● Effective ranges and transponders

Acceptance steps that you must execute in order to operate the Mobile Panel 277F IWLAN
HMI device in a system with effective ranges are described in detail in these operating
instructions.

The following manuals contain more detailed notes on acceptance of the system:

● Function manual "Fail-safe operation of the Mobile Panel 277F IWLAN"

● Manual "S7 distributed safety, configuring and programming", Chapter "System
acceptance test".

Acceptance of the effective ranges and transponders

For acceptance of the effective ranges and transponders you must determine a CRC
checksum in the plant and enter it in the project. After subsequent project transfer to the HMI
device you can operate the plant with the HMI device.

Note
If you change transponders in the plant you must execute another acceptance of the plant.

When executing an acceptance test of the system, all of the relevant application-specific
standards must be observed.

7.5.4.2 Accepting effective ranges and transponders

Introduction

For safe operation, the project of the HMI device must precisely match the plant.
For this reason when first starting a project in the plant, you must verify all effective ranges

with all transponders. The result of the verification is a CRC checksum that you must enter in
the project. Then you must transfer the project to the HMI device again.

Note
Transponders that are exclusively assigned to one zone are not considered in this

verification.

8.1 Organizational measures

The HMI device should only be operated in the system with a battery or in the charging
station.

To ensure fail-safe operation of the HMI device the organizational measures described
below must be complied with.

Storing the HMI device

WARNING

Non-functional emergency stop button
If the HMI device is not integrated, the emergency stop button does not function.
To avoid confusion between effective and non-effective emergency stop buttons, only one

integrated HMI device should be freely accessible.

If the HMI device is not in use, it must be stored in a locked area.

8

Handling the HMI device during operation

CAUTION

Shutdown or rampdown of the system due to empty battery
An integrated HMI device with flat battery triggers a communication error. This results in the

following reaction of the F CPU:

• If the HMI device is logged on at the effective range: Shutdown

• If the HMI device is not logged on at the effective range: Global rampdown

Check the charge status of the battery of the ready-for-operation device via the "BAT" LED.

• Recharge the HMI device in good time.

To charge the batteries, the ambient temperature / battery temperature must not exceed
40 °C The higher the temperature, the longer it will take for the battery to charge.

Find a place with a cool ambient temperature for the charging station. If necessary,
allow the battery to cool first. You can check the battery temperature in the "OP" dialog
box, "Battery" tab in the Control Panel.

Alternatively, change the main battery.

Fail-safe mode

8.2 Switch-off behavior

The following must be noted when working with the Mobile Panel 277F IWLAN:

● Pay attention to the "SAFE" LED.
If the HMI device is integrated in fail-safe communication, the "SAFE" lights up and the

emergency stop button is active.

● Pay attention to the "COM" LED.
If you leave the area with sufficient WLAN coverage, the "COM" LED will flash.

Communication between the HMI device and PLC is down. You can no longer operate
the system with the HMI device.

● Check the "RNG" LED when the HMI device is logged onto the effective range.
The "RNG" LED indicates when the HMI device is logged onto the effective range.

Logging onto the effective range is required for the enabling button to be active.

CAUTION

Unauthorized operation possible
It is not permitted to leave the effective range without an HMI device while the HMI

device is logged on to the effective range.

8.2 Switch-off behavior

Introduction

Different switch-off behavior is possible depending on the situation in the plant:

● Emergency stop

● Shutdown

● Local rampdown

● Global rampdown

Plant switch-off differs in its triggers and effects.

DANGER

No triggering of safety states
The switch-off behavior described is only triggered in the system if the F CPU has been

programmed accordingly.

Emergency stop

Press the emergency stop button to trigger the emergency stop. The emergency stop
depends on the effective ranges. If the emergency stop button is pressed, the F CPU
triggers an immediate stop of the machines assigned to it.

Mobile Panel 277F IWLAN

220 Operating Instructions, 12/2007, A5E01003940-01

Fail-safe mode

8.2 Switch-off behavior

The emergency stop button is always active if there is PROFIsafe communication between
HMI device and F CPU, i.e. if the HMI device is integrated in the PROFIsafe communication.
If PROFIsafe communication is present the "SAFE" LED lights up.

Shutdown

Shutdown is triggered by the F CPU. The shutdown is specific to the effective range. If the F
CPU detects a communication error for an HMI device logged on in the effective range, it
triggers the emergency stop of the machines that belong to the effective range.

Local rampdown

Local rampdown is triggered if the HMI device is logged on at the effective range and if it
leaves the effective range for longer than 30 seconds. Local rampdown is specific to the
effective range.

Local rampdown triggers a defined slow stop of the machines of the effective range.

Global rampdown

Global rampdown is triggered by the F CPU. Global rampdown is independent of the
effective ranges.

For global rampdown the following response must be programmed in the safety program of
the F CPU: If the F CPU detects a communication error for an HMI device integrated in the
PROFIsafe communication, it triggers a defined slow stop of the machines subordinate to it.

Fact

Trigger

Switch-off behavior can be triggered by the following:

● The emergency stop button is pressed.

● A communication error occurs.

● Timeout: The HMI device is logged onto the effective range and the operator leaves the

effective range with the HMI device for longer than 30 seconds.

Triggering the switch off

The following table shows the effect of the different triggers depending on the operating
situation:

8.3 Integrating the HMI device

Introduction

During fail-safe operation, a safety program runs in the F CPU. This safety program
communicates with the HMI device. The F CPU monitors the communication for errors and
evaluates the signals. The terms "integrate" and "remove" refer to integrating the HMI device
in and removing it from the safety program of the F CPU.

Integrating

Requirements

Procedure

If the HMI device is configured for the safety program, it is automatically integrated in the
safety program when the project is started. The "SAFE" LED lights up to indicate that
integration is complete.

The emergency stop button becomes active as soon as the HMI device is integrated.

● WLAN communication is established.

● The Loader is displayed on the HMI device.

● Effective ranges and transponders are accepted.

8.5 Logging onto and off from the effective range

PROFIsafe communication is terminated. The HMI device is removed from the safety
program of the F CPU. The project is terminated. If you have pressed the ON/OFF button,
the HMI device switches off.

Removal in the event of a communication error

In the event of a communication error, the F CPU removes the HMI device and initiates a
global rampdown.

The "SAFE" LED on the HMI device goes out. The project is terminated.

8.5 Logging onto and off from the effective range

Introduction

An effective range is the range in which sections of the system, for example a machine, can
be operated with the enabling buttons of the HMI device. As soon as you are in an effective
range with the HMI device, you can log the device onto the effective range. Fail-safe
operation of the system section delimited by the effective range is only possible after the HMI
device has been successfully logged on.

Note
Before leaving the effective range with the HMI device, you must log it off from the effective

range.

Requirements for logging on

● The HMI device is integrated. The "SAFE" LED lights up.

● The ID of the effective range is marked in the system.

● The HMI device is located within the effective range.

● No other HMI devices are logged onto this effective range.

● The "Effective range name" operating element is configured and displayed as follows:

"Rangename" indicates the name in the case of any effective range.

Procedure for logging on

1. Touch the "Effective range name" operating element.

The "Effective range logon" dialog box opens.

2. Read the ID of the effective range from the machine or system to be operated.

.

3. Enter the ID of the effective range.

Behavior in the effective range following successful logging on

CAUTION

Shutdown
If the HMI device is in a state where it is constantly ready for operation, the battery will lose

its charge. A flat battery will result in a communication error. The F CPU initiates a
shutdown.

Under no circumstances should the effective range be left without an HMI device while the
HMI device is logged onto the effective range.

CAUTION

Rampdown
If you leave the effective range without logging off, or the HMI device no longer recognizes

the transponder, the following steps are carried out:

• After 5 seconds, the "Effective range left without logging off" dialog box appears. If you

do not return to the effective range within 25 seconds, the HMI devices initiates a local
rampdown and begins logging off from the effective range. The HMI device is logged off
from the effective range once logging off has been confirmed. This means that other

HMI devices are free to log onto the effective range.
Return to the effective range in good time.
Always align the HMI device so that it is possible to measure the distance between the HMI

device and the transponder.

Note the displays of the HMI device LEDs; in particular, the "RNG" and "BAT" LEDs.
The HMI device will trigger the vibration alarm under the following circumstances (if

configured):

● The charging status of the battery is < 10%.

● You leave the effective range with the HMI device without logging the HMI device off from
the effective range.

8.6 "Override" mode

Introduction

The effective range functionality of the HMI device can be extended with the "Override"
mode.

"Override" mode can be used in the following cases:

● Application of existing protective measures instead of the effective range functionality
If there are already safety measurements in your system, e.g. safety gates, they can be

integrated into the safety concept with the "Override" mode.

or

● When sections of the system that are not covered by transponders (inside a robot cell, for
example) are to be operated with the enabling buttons.

In this case the system area must be secured by additional safety measurements, with a
safety gate for example.

9.3 Direct keys

9.3 Direct keys

Introduction

Direct keys on the HMI device are used to set bits in the I/O area of a SIMATIC S7.
Direct keys enable operations with short reaction times, that are, for example, a jog mode

requirement.

NOTICE

PLC stop
Please note that leaving the WLAN area will cause the PROFINET IO device to fail and will

therefore result in a PLC stop.
Determine suitable programming measures in the PLC, in order to prevent a PLC stop.
Please refer to your system documentation to check whether additional information on this

subject is available there.

NOTICE

Effectiveness of direct keys in offline mode
Direct keys are active when both of the following conditions are satisfied:

• The HMI device is in an area with sufficient WLAN coverage.

• The HMI device is in "Offline" mode.

NOTICE

If you operate a function key with direct key functionality in a running project, the direct key
function is always executed, independent of the current screen contents.

Direct keys

The following objects can be configured as a direct key:

● Buttons

● Function keys

● Screen numbers

● Handwheel

● Illuminated pushbutton

Mobile Panel 277F IWLAN

234 Operating Instructions, 12/2007, A5E01003940-01

● Key-operated switch

Direct keys result in additional basic load on the HMI device.

Additional information about direct keys is available in the system manual "WinCC flexible
communication".

Operating a project

9.4 Operator input options

9.4 Operator input options

Once the project is transferred to the HMI device, current processes can be operated and
monitored in the process control phase. You have the following options for operating the HMI
device:

● Touch screen

The HMI device is operated by means of the touch screen. The operating elements
shown in the dialogs are touch-sensitive. Touch objects are basically operated in the
same way as mechanical keys. You activate operating elements by touching them with
your finger. To double-click them, touch an operating element twice in succession.

CAUTION

Do not use any pointed or sharp objects when operating the touch screen. Otherwise
this may damage the plastic membrane of the touch screen.

● External input devices

The following operator controls can be connected externally:
– Keyboard, connected via USB
– Mouse, connected via USB
The use of external input devices is recommended for commissioning.

Operating a project with an external keyboard

An external keyboard can be used to operate a project in exactly the same way as with the
HMI keyboard or screen keyboard.

Note
The function keys of the external keyboard are disabled.

Use other keys on the external keyboard, which correspond to the HMI device keys.

Operating a project with an external mouse

An external mouse can be used to operate a project in exactly the same way as with the HMI
touch screen. Click the described operating elements with the mouse.

9.4 Operator input options

Unintentional actions

CAUTION

Do not carry out several operations simultaneously. You may otherwise trigger
unintentional actions.

• With touch control:

Always touch only one operating element on the screen

• With key operation via an external keyboard:

Do not press more than two keys simultaneously

Observing the plant documentation

Some operations with the project may require in-depth knowledge about the specific plant on
the part of the operator. Proceed with caution, for example, when you use jog mode. Please
refer to your system documentation to check whether additional information on this subject is
available there.

Operation feedback from operating elements

The HMI device provides optical feedback as soon as it detects that an operating elements
has been selected. The operating element receives the focus and is selected. This selection
is independent of any communication with the PLC. Therefore this selection does not
indicate whether the relevant action is actually executed or not.

The configuration engineer can also configure the selection of an operating element so that it
deviates from the standard. Please refer to your system documentation to check whether
additional information on this subject is available there.

Optical feedback from operating elements

The type of optical feedback depends on the operating element:

● Buttons
The HMI device outputs different views of the "Pressed" and "Unpressed" states,

provided the configuration engineer has configured a 3D effect:
– "Pressed" state:

A "Unpressed" state:

Mobile Panel 277F IWLAN

236 Operating Instructions, 12/2007, A5E01003940-01

Operating a project

9.5 Function keys

The configuration engineer determines the appearance of a marked field, for example,
line width and color for the focus.

● Invisible buttons

By default, invisible buttons are not displayed as pressed when they are touched. No
optical operation feedback is provided in this case.

The configuration engineer may, however, configure invisible buttons so that their outline
appears as lines when touched. This outline remains visible until you select another
operating element.

● I/O fields

When you select an I/O field, the content of the I/O field is displayed against a colored
background. With touch operation, a screen keyboard is displayed for the entering of
values.

9.5 Function keys

Function keys

Function key assignment is defined during configuration. The configuration engineer can
assign function keys globally and locally.

Function keys with global function assignment

A globally assigned function key always triggers the same action on the HMI device or in the
PLC irrespective of the screen displayed. Such an action could be, for example, the
activation of a screen or the closure of an alarm window.

Function keys with local function assignment

A function key with local function assignment is screen-specific and is therefore only
effective within the active screen.

The function assigned locally to a function key can vary from screen to screen.
The function key of a screen can be assigned one function only, either a global or local one.

The local assignment function takes priority over the global setting.
The configuration engineer can assign function keys in such a way that you can operate

operating elements with function keys, for example, the alarm view, trend view, recipe view
or status / PLC.

Multi-key operation

Unwanted actions may be triggered, if the operator unintentionally actuates a key
combination.

9.15.1 Overview

Application

The Sm@rtClient view enables you to monitor and remotely operate the current project of a
remote HMI device. With the correct configuration, several equal priority HMI devices can
access a remote HMI device.

Layout

Monitoring mode

Operation

Note
If another HMI device accesses your HMI device via the Sm@rtClient view, this leads to an

additional load on your HMI device.

In the Sm@rtClient view, the remote HMI is displayed with the complete layout.
Depending on the configuration, you can monitor and also operate this screen.
You can also operate the function keys like buttons on an HMI device with a touch screen.

On a Sm@rtClient view which is configured for monitoring mode, you can only monitor the
remote HMI device. You cannot control its operation.

Note
It is not possible to operate the direct keys of the remote HMI device from the local HMI

device.

The available operator controls depend on the HMI devices used:

● Same type of HMI devices

Scroll bars are displayed if the screen of the remote HMI device is larger than that of the

current HMI device.

Procedure for forcing permission

If several HMI devices have access to a HMI device, only one HMI device has operating
permission at any one time.

Two cases must be distinguished for this case:

● If another HMI device is already controlling the remote HMI device, if configured
accordingly, you can force operating permission for the remote HMI device

– You are trying to operate the remote HMI device

subject is available there.

9.16 Project security

9.16.1 Overview

Design of the security system

The configuration engineer can protect the operation of a project by implementing a security
system.

The security system is based on authorizations, user groups and users.
If operating elements protected by a password are pressed, the HMI device first requests

that you log on. A logon screen is displayed in which you enter your user name and
password. After logging on, you can press the operating elements for which you have the
necessary authorizations.

The logon dialog can be set up by the configuration engineer via an individual operating
element.

In the same way, the configuration engineer can set up an operating element to log off. After
logging off, objects assigned password protection can no longer be operated; to do so, log
on again.

Please refer to your system documentation to check whether additional information on this
subject is available there.

Central user administration using SIMATIC Logon

Users, user groups and authorizations can be stored on a central server.
If user administration cannot contact the server, an error message is displayed. If this is the

case, you can only log on locally. Check whether additional information is available in your
plant documentation.

The operation of SIMATIC Logon differs as follows:

● The simple user display is not supported

● Users cannot be deleted

● You cannot change your logout time

● When changing the password, you must enter it twice for security reasons

● The domain name is also indicated in the "User" field

User groups and authorizations

Project-specific user groups are created by the configuration engineer. The "Administrators"
and "PLC User" groups are included in all projects by default. User groups are assigned
authorizations. Authorization required for an operation is specifically defined for each
individual object and function in the project.

Users and passwords

Each user is assigned to exactly one user group.
The following persons are allowed to create users and assign them passwords:

● The configuration engineer during configuration

● The administrator on the HMI device

● A user with user management authorization on the HMI device

Irrespective of the user group, each user is allowed to change his own password.

Logoff times

A logoff time is specified in the system for each user. If the time between any two user
actions, such as entering a value or changing screens, exceeds this logoff time, the user is
automatically logged off. The user must then log on again to continue to operate objects
assigned password protection.

Backup and restore

Note
Backup and restore is not available to central user administration with SIMATIC Logon.

The user data is encrypted and saved on the HMI device to protect it from loss due to power
failure.

9.16 Project security

The users, passwords, group assignments and logoff times set up on the HMI device can be
backed up and restored. This prevents you having to enter all of the data again on another
HMI device.

NOTICE

The currently valid user data is overwritten in the following cases:

• Depending on the transfer settings, when the project is transferred again

• Upon restore of a backed-up project

• Upon import of the user administration via an operating element. Please refer to your

system documentation to check whether additional information on this subject is
available there.

The retransferred or restored user data and passwords are valid with immediate effect.

Limits for user, password and user view

Number of characters
Length of user name, maximum 40
Length of password, minimum 3
Length of password, maximum 24
Entries in user view, maximum 50

9.16.2 User view

Application

The user view is used to display the users on the HMI device:

● All users on the HMI device are displayed in the user view to the administrator or to a

user with administrator authorizations

● If you are a user without user management authorization, you can only see your personal

user entry

The authorizations of a user after logging on depends on the user group to which the user is
assigned.

Please refer to your system documentation to check whether additional information on this
subject is available there.

Layout

The configuration engineer can implement a simple or extended user view.
The two user views offer the same functions. They differ only in the display of information.

and user group.

Extended user view

The extended user view displays information about the users.

The extended user view contains the following columns:

● Users

● Password

● Group

● Logoff time

The passwords are encrypted by appearing as asterisks.
