Introduction

Use of the TP 170A

The TP 170A is the basic touch panel for all SIMATIC S7 CPUs It is the first touch panel unit in the SIMATIC HMI product range and is based on the operating system Microsoft Windows CE.

The TP 170A is suitable for all basic functions It has an interface which can be used for both the MPI and the Profibus-DP The unit memory is designed for smaller configurations The objects used for a configuration can be buttons, bar graphs, graphics and messages

Area of use of the TP 170A

The TP 170A has been conceived for machine operation and monitoring It

provides a realistic graphical representation of the machine or system to be

monitored Its area of use includes implementation in machine and apparatus construction as well as in the packing and electronics industry.

The high degree of protection (IP65 on the front side) and non-implementation of moving storage media, such as hard disks and floppy disks, ensure the TP 170A is also suitable for use in rough industrial environments and directly on site on the respective machine.

The TP 170A can be installed in switching cabinets and operating consoles Due to the fact that the TP 170A is equipped with high performance basic

hardware and has a minimum installation depth means that it fulfills all the

requirements for operation in the vicinity of the machine.

Easy to operate and observe

The TP 170A enables operating statuses and current process values concerning a connected PLC to be graphically displayed and the relevant machine or system to

be easily monitored and operated Display and operation of the TP 170A can be adapted optimally for the respective process requirements by using the

configuration software ProTool/Lite, ProTool and ProTool/Pro CS (from

Version 5.2)

The TP 170A can be used to:

control and monitor the process intuitively Setpoint values or control element settings, for instance, can be modified by entering values or touching configured buttons;

display processes, machines and systems graphically;

visualize operating and alarm messages and process tags, e.g in output fields, bar graphs or trend curves;

intervene directly in the operation by means of the touch-sensitive screen.

Operating unit configuration (principles)

Graphics, texts and operating and display elements which need to be represented

on the operating unit must first be created on a configuration computer (PC or PU) using the configuration software The configuration computer must be connected to the operating unit in order to download the project to the operating unit (refer to

“Configuration phase” in Figure 1-1)

Once the project has been successfully downloaded, connect the operating unit to the PLC The operating unit can then communicate with the PLC and respond according to the information configured for running the program in the PLC (refer to

“Process control phase” in Figure 1-1)

Start downloading automatically when the operating unit is in operation

The operating unit can be switched automatically to Download mode from normal operation as soon as downloading is started on the connected configuration computer This option is especially recommended for the test phase of a new configuration because the transfer is performed without intervention in the

operating unit A condition for this is that the following settings are defined in the Configuration menu (Figure 3-2):

The bus parameters (e.g MPI address, baud rate, etc.) are read out of the

configuration which has been loaded on the operating unit Important: A new project with new parameters must initially be loaded on the operating unit with the

old settings (on the configuration computer) because the old parameters apply

here.

The following options can be set for Download mode:

The operating unit can be switched from normal operation to Download mode automatically as soon as downloading is started on the connected configuration computer.

Download mode can be restricted to a specific connection type so that downloading is only performed via a serial or an MPI connection.

Simulation on a configuration computer

A simulator is supplied with the configuration software which can be used to test your configuration without the necessity of a connection to a PLC A condition for this is that the runtime software is installed on the same configuration computer on which the configuration software is loaded The runtime software is contained on the configuration software installation CD.

The simulator is an individual application It simulates the configuration offline, i.e without the necessity of a physical connection to a PLC The PLC is simulated by the software.

Start the simulator by clicking on the symbol depicted on the left or by using the menu command File → Test → Start simulator.

Detailed information on operating the simulator is provided in the ProTool

Configuring Windows-based Systems user’s guide and in the configuration

software online help.

Note:

For the test phase of a configuration, it is recommended to initiate Download mode from normal operation automatically Further information is available on Page 3-4.

Test with connected PLC

When a PLC is connected, it is possible to test the communication between the operating unit and PLC This test also determines whether the correct data areas have been configured.

Operating the TP 170A

Operating concept

The screen is used to observe the operating status of the machine or system being monitored and, at the same time, to intervene directly in the process running simply by touching the buttons and input fields displayed.

Definition

Touch elements are contact–sensitive operating elements provided on the touch panel screen, such as buttons and input fields Their operation is basically no different from pressing conventional keys Touch elements are operated by

touching them lightly with your finger or a suitable object.

Note

Never use pointed or sharp instruments to operate the Touch Panel to prevent damage to the plastic surface of the touch screen.

! Caution Never touch more than one touch panel screen element at a time If you do, an

unintended action may be initiated.

Operation acknowledgement

As soon as the touch panel detects valid contact with a touch element, it responds

by displaying a visual acknowledgement An acknowledgment is independent of communication with the PLC It is not an indication of the required action actually having been executed.

The type of visual acknowledgement is dependent on the operating element touched:

Buttons

In the case of 3D–effect configurations, visual representation is distinguished according to the statuses touched and untouched Examples of representation are illustrated below by means of the Status button:

Untouched Touched

Input fields

After an input field has been touched, the system keyboard illustrated in Figure 4-1 appears as the operation acknowledgement.

Password protected operating elements

If an operating element is touched which has been assigned with a password protection, without the user having logged in on the operating unit beforehand, a system message is triggered The password protected function is not executed Further information on this subject is available in the Chapter 5.4.

Operating the TP 170A

Principles of operation

Input fields are used to enter digits and texts (characters 0 to 9 and A to F ) To do

so, touch the corresponding field The system keyboard appears.

After an entry has been made correctly, the system keyboard automatically

disappears and the entered value is accepted in the input field.

System keyboard

The buttons available for operation on the system keyboard are dependent on the type of value to be entered Buttons which are available for operation are

highlighted, and those not available appear simply as empty areas.

Figure 4-1 illustrates an example of the system keyboard for entering decimal values Table 4-1 explains the significance of each individual button.

Operating the TP 170A

What is a screen?

Screens visualize the progress of processes and display specified process values.

A screen contains logically related process data which the operating unit can both display and modify by operating the individual values.

Screen partitions

A screen is basically composed of static and dynamic sections The terms “static” and “dynamic” do not refer to the possibility of dynamically positioning screen partitions but to the connection to the PLC.

Static partitions, e.g text and graphics, are not updated by the PLC Dynamic partitions, e.g input and output fields and bars, can be linked to the PLC and display current values constantly read in from the PLC memory Their connection

to the PLC is established by means of tags.

Screen objects

Various screen elements are used to display and operate a screen:

Output fields Input fields Texts Graphics Status buttons Bar graphs Message view

A summary of all the screen objects which a TP 170A project may contain is provided in Chapter 5.

This chapter introduces the screen objects which may be contained in a

configuration and explains their operation It provides the following information:

a summary of screen objects (Page 5-2) the Status button (from Page 5-3) messages (from Page 5-5) logging in and out of the operating unit (Page 5-7)

Notes on operation are provided on Page 5-6

Operation of Screen Objects

In addition to the tags, which represent the current switch status, the configuration software can be used to define text or graphics for the two statuses ON and OFF.

Option push button:

The Status button reacts as a key-in button When pressed, the Status button changes to the status ON It remains in this status as long as the Status button

is pressed When released, it automatically switches back to OFF.

Event-related initiation

Use the configuration software to assign the Status button one or more functions and to define which events result in the respective function being triggered The events which can be configured are:

If the status of the Status button changes from the type switch due to a

modification of the configured variables, none of the described events is triggered.

Operation of Screen Objects

Representation

When the Status button is set to switch, the configuration software can be used to assign different text or graphics to indicate the status of the button during runtime Figure 5-1 illustrates an example of a Status button when pressed (left) and not pressed (right).

What are messages?

Messages which appear on the operating unit indicate events and statuses related

to the control process and operating unit itself A message can contain text and tags.

The operating unit differentiates between event messages and system messages:

Event messages

indicate the status in a process, e.g Motor ON Event messages are configured They are triggered when a bit is set in the PLC.

System Messages

are triggered by the operating unit They do not have to be configured.

System messages indicate incorrect operations or communication faults, for example A time period can be considered for system messages in the configuration software This defines how long a system message appears on the operating unit.

A list of the most important system messages is provided in the Appendix C.

Message events

These messages are triggered according to events Message events on the

TP 170A include:

Message arrival

A message which has been triggered is considered as having arrived As soon

as message is triggered, it is displayed in the operating unit message display and is then considered as queued.

Operation of Screen Objects

Message view

The TP 170A can display up to 16 messages in the message view If more than 16 messages are present simultaneously on the operating unit, the oldest message in the queue is deleted.

It is possible to define specific views of the messages to be displayed in the message view Various filter criteria is available for this in the configuration

software.

The following can be configured

Message categories (event and system messages only) Number of columns

Number of lines per message Sorting (oldest or latest message at the top) Maximum number of visible messages The figure illustrates an example of a message view with the configured columns Date

Time Message number Message status Message text

Connection discontinued: Station 2, Rack 0, Slot 0

Synchronize date and time

In order to synchronize the date and time on the operating unit with the PLC, the area pointer Date/Time PLC must be set up in the project in ProTool/Pro CS During runtime, the operating unit accesses these data areas in the PLC for reading purposes and synchronizes the date and time in the configured acquisition cycle with the PLC This data is provided, for example, in the message time stamps issued in the message display.

Detailed information concerning the area pointers is provided in the

ProTool Configuring Windows-based Systems user’s guide, in the configuration software online help and in the Communication for Windows-based Systems user’s manual.

Operation of Screen Objects

During the configuration, input fields and buttons can be protected against

unauthorized operation by assigning passwords Important parameters and

settings can then only be modified by authorized personnel The password is defined at the moment the element is configured and cannot be modified via the operating unit.

Logon

If operating elements are to be assigned password protection in the configuration,

it must be possible for the operator to log on In this case, the function Logon_User must be linked with an operating element, preferably an input field, in the

configuration.

In order to access a password protected operating element during runtime, it is necessary to log on on the operating unit It is then possible to access all password protected operating elements up to the point of logging off from the operating unit.

Logoff

In order to rule out operation by unauthorized personnel, the logon should not remain active on the operating unit for too long a period of time The following options are available with which to log off from the operating unit:

Configured logoff time expires

If the operating unit is not operated by the user within the configured period (logoff time), he is automatically logged off from the operating unit.

Log off of the operating unit

If the configuration links the function Logoff_User with an operating element, the element can be used log off from the operating unit.

Operation of Screen Objects

System Settings

Conditions for changing operating modes

In order to switch between the operating modes described below, the function Change_mode must be linked to an operating element in the project.

When using this mode, processes can be operated and visualized without

restriction There is a logical connection between the operating unit and PLC or the operating unit attempts to establish one.

Online mode is the predefined operating mode each time the operating unit is started up.

Download mode

This operating mode is used to transfer a configuration from the configuration computer to the operating unit Further information on Download mode is provided

in Chapter 3.3.
