1.4 Mounting the Terminals

The terminals with mounting bolts or lateral mounting slits are mounted from the
rear side. The rear panel mounting is suitable for easy and sealed installation plac­es where the rear side of the unit is accessible.

The terminal NT15S-SF121B-E is mounted from the front side. This type of in­stallation is suitable for easy and sealed installation where the rear side of the unit is
not accessible.
The terminals are particularly suitable for mounting in control cabinets with a
mounting plate thickness of approximately 1 to 10 mm.
The front panels permit sealed installation of the units in accordance with the IP65
degree of protection.

The terminals

- NT4S-SF123B-E

- NT18S-SF121B-E

- NT15S-SF121B-E
have a circumferential groove milled into the rear side of the front plate, containing
a rubber sealing.

The terminals

- NT4S-SF121B-E

- NT4S-SF122B-E
are equipped with a foam sealing on the rear side of the front plate.

All parts for mounting the units are supplied with the spare parts set.
Special care needs to be taken during installation to maintain this high degree of
protection. The appliance is inserted from the front through the mounting panel
cutout and fastened with the fasteners of the spare parts set. The sealing must be
positioned evenly and the fastening elements tightened uniformly.
When installing the terminal, keep a minimum space of 30 mm around the terminal
for adequate air circulation.

The tightness between the front panel and the mounting surface depends on
the care during installation.

Mounting and connection of the operating terminal to the power supply must be
carried out by authorized and qualified personnel with EMC training.
Operating terminals must be grounded according to regulations.
The application-specific safety- and accident prevention regulations must be ob­served during the mounting and connection to the power supply, e.g.:

- EN 60204, Electrical Equipment of Machines

- EN 292, Safety of Machinery, General Principles for Design

- DIN 57 100 Part 410, Protection against Electric Shock

Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!

1.5 Pin Assignments

The operating terminals are equipped with a universal interface by default. This
universal interface combines several interface standards within one physical con­nector. The connector is divided into two channels. The channel for communication
(SER1) is divided from the channel for download/upload/printer (SER2). The chan­nels can operate independent of each other.
The channel for communication (SER1) can handle - specified by protocol - only
one of the three interface standards.

1.7.4 Contrast Setting

The contrast for the display can be adjusted by means of the software. This re­quires the system variable LCDContrast to be set up in an I/O mask of the applica­tion. The value can then be modified using any editor that can handle integer num­bers.
The limit values for the contrast must be set to

Lower level: -25
Upper level: +70

If this variable is not defined in the menus or the value is out of the range of values,
the default setting (value 25) will be loaded when the system is initialized.
The system variable can be stated in any I/O-mask of the application!

S3 OFF
S4 ON

This switch position coincides with ‘activating download by hardware’. The contrast
will be reset before the warning is displayed. The warning will be displayed in a
legible manner. Upon display of this warning, switch off the terminal, set the switch
4 to the OFF-position and switch the terminal on again. The application description
is not lost.

1.9 Battery

A built-in lithium battery buffers the data in the RAM memory and also supplies the
real-time clock with power. The discharge degree of the battery is monitored con­stantly to prevent any loss of data.
The battery provides a minimum life of 5 years, even under unfavourable operating
conditions.
If the battery is drained the system message ‘change battery’ is generated.
A new battery is supported by OMRON EUROPE.

Replacing the battery:
The battery can be replaced while the operating voltage is connected to ensure that
the message data and time setting are not lost. Mind the safety instructions!

- Remove the mounting bolts of the 25-pin interface connector

- Remove the fastening screws of the enclosure and remove the enclosure

- Replace the cable fastener, which is used to fasten the battery

- Plug off the cable of the battery and replace the discharged battery

- Plug on the cable of the new battery

- Fasten the new battery on the plastic holder on the printed circuit board

OBSERVE THE CORRECT POLARITY OF (−) AND (+)

- Place the enclosure on the rear side of the terminal

- At first fasten the bolts of the interface connector and at last fasten the screws of
the enclosure properly

Changing the battery may only be performed by qualified and authorized person­nel!

Sewage and refuse disposal:
Dispose only drained batteries into the collection box of the community or of the
local dealer. The battery is stated as drained when the message ‘change battery’
appears on the display of the terminal.

To prevent short circuitry in the collection boxes insulate the poles of each battery
with insulation tape or put each single battery into a plastic bag.

Do not put lithium batteries in fire or heat them above 100 !C and do not recharge
them. Danger of Explosion!

Do not open lithium batteries. Danger of Poisoning!

Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!

The Terminals of the NT-Series Section 1-11

1.10 Fuse

A semiconductor fuse is used to prevent damage to the operating terminal. Once
the fuse has been activated, the device must be disconnected from the supply
voltage to allow the semiconductor fuse to regenerate. With an ambient tempera­ture of 20 !C, the regeneration takes about 20 seconds. The higher the ambient
temperature, the longer the regeneration period.
The semiconductor fuse is not designed to be replaced.

Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!

Electrostatic discharges can damage electronic components! ESD protective mea­sures must be observed!

1.11 Application Memory

A 256 kByte flash memory is used as an application memory for each operating
terminal . This memory area is available to store the user application, the loadable
protocol driver, the fonts and the recipe data. The advantage of the flash memory is
that programming and deleting processes can be carried out directly in the termi­nal.

Changing the application memory may only be performed by qualified and autho­rized personnel!

Hazardous voltages can exist inside electrical installations that can pose a danger

SECTION 3

Operating Modes

This section describes the two available operation modes, the standard mode and the transparant mode
and indicates how to select the operation mode.

Operating Modes Section 3-1

3 Operating Modes

There are two types of operating modes available in the operating terminals, the
standard mode of operation and the transparent mode of operation.

Terminals operating in the transparent mode represent full-size ANSI-terminals.
Each key generates a press and release code, which will be transmitted via the
interface SER1 in the form of an ASCII character. The displays and the key LEDs
are controlled via ESC sequences. The number of character sets and character
attributes varies with the type of display. For a detailed description please refer to
the chapter ‘Transparent Mode’.

In the standard mode of operation, the entire operating system is integrated in the
terminal. The standardized operating concept

completely frees the connected con­troller from any operator guidance tasks as well as data display.In standard mode, a
decoding of the keys or selection of masks from within the controller is not required.

3.1 Setting the Operating Mode

The operating mode can be set by means of the User-Mode-Switch. The terminals
are factory-set to the standard mode of operation.
The user-mode switch is accessible at the side of the terminal NT4S-SF122B-E
and at the rear side of all other operating terminals.

User-Mode Switch 4 Switches 8 Switches

Operating Modes Section 3-1

The switches S5 to S8 can be used by the operator as needed. The switch positions
are stored at initialization time and afterwards they can be overtaken to the controll­er.

Standard Mode Section 4-1

4 Standard Mode

The standard mode is the mode of operation in which the terminals are most com­monly used and that provides the highest performance. In this mode of operation,
the terminals act as intelligent peripheral devices for the controller by performing
controlled pre-processing of the visualization data, thus completely relieving the
connected controller of all operating tasks. This reduces the programming effort
required by the user, the run time and memory required in the PLC.
Communication processors have been dispensed with in the PLC and program­ming unit interfaces have been used throughout, making the PLC connection very
economical. The operating concept is a universal one, thanks to the large number
of supported protocols. Operation of the machine has been made independent of
the type and manufacturer of the controller.
The standard mode is supported by every operating terminal. The system’s flexi­bility means you can customize all menus and dialogs according to your particular
application. Extremely sophisticated operator guidances can be configured with
the aid of masks, system variables and control and function keys. In standard
mode, all functions which can be executed with the terminal, mask contents, texts,
messages and variables are stored in the user description (mask definition). After
the programming phase is complete, the user description is stored in the operating
terminal’s Flash memory.
In the description which follows, the term ‘

user

’ refers to individuals who configure

or program the operator interface, while ‘

operator

’ refers to individuals who monitor

and operate the data of the installation on site.

4.1 Setting the Operating Mode

The standard mode of operation can be set with the user-mode switch. Turn off the
terminal before selecting the mode of operation.

All terminals are factory-set to the standard mode.
The ON/OFF positions on the mode selector switch are marked.
The selected mode of operation becomes active as soon as power is supplied.
Position of the switch for the standard mode:
S1 ON S5 not used
S2 not used S6 not used
S3 OFF S7 not used
S4 OFF S8 not used

Fig. 1: User-mode switch

Standard Mode Section 4-2

4.2 Startup Process

All LEDs in the terminal are initially lit when the power is applied. A system-test is
then performed that includes testing and initialization of the modules in the oper­ating terminal. Various system and error messages may be output during this sys­tem-test. If the application memory contains a valid user description, the first mask,
the Start-Mask, or the mask specified in the language parameters as the mask to
be used as the Start-Mask will appear on the display.
This mask is displayed for 5 seconds (fixed time setting). This time can be used by
the operator to visually inspect the LEDs and the screen for proper functioning.
After this time period, the Main Mask or the mask specified in the language para­meters as the Main Mask is displayed. This mask is the first mask of the operator
guidance.
If the Enter keyis pressed while the Startup Mask is displayed, the Setup Mask will
appear on the display. This Setup Mask can be used to set the parameters for the
interface and the operating terminal.
If the Enter key is pressed before the Startup Mask is displayed, an error message
will be generated during the keyboard test.

.......The self-test performed on the keyboard during

the terminal start-up has detected that a key is
pressed. Comply with the request and release
the key. If this message is generated when no
key is pressed, this indicates a defective key­board. Generally, the message will disappear
after releasing the key/keys.

A longer delay may occur before the Startup Mask is displayed if the statistics
memory contains a large number of messages from the serial message system.
This time period (initialization period) is required to set up the structures for mes­sage management, which will then enable faster sorting of messages later. During
the initialization phase, the following message is displayed:

.......When the terminal is switched on, the mes-

sages that are present in the terminal are sort­ed. This process requires a certain length of
time (initialization time).

Standard Mode Section 4-4

4.2.1 Startup Process without a Valid User Description

The system-test performed on the application memory will detect whether a mo­dule is missing, defective or of the wrong type. This is then indicated to the operator
by the following message:

If the memory test establishes that the right type of Flash memory is used but that it
does not contain a valid user description, the Flash memory will be erased and the
terminal will automatically switch to the download operating mode. The following
messages appear on the display indicating the various phases:

The message ‘DOWNLOAD 1’ remains on the display to indicate that the terminal
is now ready to receive a valid user description via the download interface.

Until the memory contains a valid user description, communication with a controller
will not take place, nor will the keyboard be operational. Once a valid user descrip­tion has been downloaded, the terminal becomes active.

4.3 Communication in the Standard Mode

In standard mode, any interface except the interfaces for the logging printer and the
parallel outputs can be used for communication between the PLC (host computer,
etc.) and the operating terminal. The interface labeling, however, always depends
on the connected counter part or the network.
See relevant chapters in the manual for a more detailed description of the various
interfaces.

4.4 Operating Concept

The operating concept of the terminal has been designed to allow the operator to
access all masks - and thus all the data - quickly and easily.
A number of means are available to the user to help guide the operator through the
mask system.

4.4.1 Mask Structure

By means of the programming system, a network of I/O masks without a real hie­rarchical structure is formed. I/O masks are located at the nodes in the network and
contain a selection field which is used to call up other masks by their names. It is
possible to access any other I/O mask from an I/O mask by using the control and
function keys.

66

Standard Mode Section 4-4

4.4.2 External Mask Selection

Mask calls from the controller are handled in the same way as messages. This
requires simply that 8000H is added to the desired mask number prior to transfer.

When the same number is assigned to a mask and message, both the mask and
the message are called up during external mask selections.
This effect can be used to provide help in a mask. Otherwise, ensure that different
numbers are used for masks and messages.

A mask called up externally is considered selected once the desired mask number
appears in the variable ,Image of Mask Number.. The acknowledgement from
the serial message channel is not a reliable confirmation of the mask output.

Example 1: Mask number and message number are not identical
A project comprises masks with numbers ranging from 100 to 200; the first mes­sage has the number 10.
Mask 118 is to be called up by the controller.
The following adding operation must be performed in the controller:

118 + 8000H = 76H + 8000H = 8076H.
The value 8076H must be written to the address of the serial message channel.
Only mask 118 is displayed.

Example 2: Mask number and message number are identical
A project comprises masks with numbers ranging from 1 to 100; the first message
has the number 10.
Mask 50 and serial message 50 are to be called up by the controller.
The following adding operation must be performed in the controller:

50 + 8000H = 32H + 8000H = 8032H.
The value 8032H must be written to the address of the serial message channel.
Both the mask 50 is displayed and message 50 are written to the message buffer.

4.4.3 Password Protection, Access Authorization

The operating concept incorporates a password protection function. Password
protection prevents masks from being accessed and the data they contain from
being altered without proper authorization. The protective function is available in
every operating terminal. It is obtained by assigning access levels to masks and by
using passwords.
Unless otherwise specified by the programmer, the access levels of all masks auto­matically default to the lowest level (=0), i.e. no password is required to access all
masks with this access level.
Two authorization levels, referred to as the edit level and the view level, are as­signed to every password.
View level means that the next mask can be viewed after entering the password but
the values in it can also not be edited.
Edit level means that the mask can be viewed after entering the password and the
values in it can be edited.

67

Standard Mode Section 4-4

Up to eight different passwords with a length of up to 11 characters can be defined.
When defining the passwords, the access authorizations should be entered in a
hierarchical structure.
Example:

- password for the manufacturer of the system, machine, etc.

- password for servicing on site

- password for the machine setter, master craftsman, foreman etc.

- password for the system operator

The following figure illustrates how the access levels, edit and view levels work:

Fig. 2: Access levels

An access level (represented here by the height (1) of the walls) can be assigned to
every mask and a view level (length of ladder 2) and edit level (length of ladder 3)
can be assigned to every password.

A password must be entered for viewing onlyof a mask (5) that has been assigned
an access level (access level is greater than 0). The password must have been
assigned a view level (ladder 2) high enough to be able to get over the access level
(view wall). The mask (5) can then be viewed (through window 4) but the variable
values can not be edited.

For viewing and editing the variable values in a mask (5), a password must be
supplied which has a view level (ladder 2) and an edit level (ladder 3) that are both
high enough.

The following rules apply to passwords:

- Access is permitted if the view and edit level values are greater than or equal to
the values specified for the access level.

- The edit level must be equal to or less than the view level.

- The higher the values for the view level and edit level, the higher the degree of
authorization.

- The valid range of values for the view level and edit level is 0 to 255.

- The default setting for both is 0.

68

Standard Mode Section 4-4

The Data Release key will have no function if pressed with an insufficient edit level.
The password can be entered in any I/O mask. Note that the Setup Mask is an
exception. The system variable MskchgPasswd is designed to prompt for pass­word entry. If the Password Editor is selected in the programming system, pass­words will not appear as they are entered on the terminal. Instead the character ‘X’
appears for every character that is entered.

Example:

Enter PASSWORD: XXXX

This example illustrates hidden entry of a 4-digit number. If an invalid password is
entered, the authorization levels will automatically reset to 0.
It is recommended that at least one password - the master password - is pro­grammed with the highest authorization level. The first password entered in the
password list via the programming system is the master password and as such has
a special function. The master password is unique in that it can not be changed on
the operating terminal. Furthermore, it can be used to reset all modified passwords
to the default values entered in the programming system.

Example:
Mask 5 access level = 10
Mask 6 access level = 20
Mask 7 access level = 30
Password 4712 Edit level = 15 View level = 25

Once the password ‘4712’ has been entered, the following accesses are permitted:

- Mask 5 will be displayed, editing of values is authorized

- Mask 6 will be displayed, editing of values is

not authorized

- Mask 7 will

not be displayed, editing of values is not authorized

The access level for the Startup Mask is always 0.
The Setup Mask is an exception with regards to the password and external data
release functions. Since no communication is taking place when the Setup Mask is
displayed, the external data release function is not applicable. To restrict access,
passwords must be used. By defining the first editable variable in the Setup Mask
as a Password Editor, all further variables can be protected against unauthorized
access. The view level does not apply when accessing the Setup Mask. Viewing is
always permitted if a value less than or equal to 254 is selected for the access level
of the Setup Mask.
The edit level for all variables of the Setup Mask, with the exception of the Pass­word Editor, is the same as that defined as the access level.
Access to the mask is always denied if an access level of 255 is defined for the
setup mask. This means that it will no longer be displayed during initialization of the
terminal and can therefore not be selected. However, all terminal-specific param­eters can also be edited in any I/O mask. The new parameters become effective by
restarting the terminal or with the system variable Boot.

69

Standard Mode Section 4-4

4.4.3.1 Reactivating the Password Protection

The access authorization for a mask or variable is reset whenever

- the operating terminal is switched off and turned back on

- an incorrect password is entered

- bit 2 in the ,Write Coordination Byte. is set

- the system variable MskchgResPasswd is activated

- the option Reset Password in the mask parameters of the password-protected
mask is selected.

4.4.3.2 Password Management

Passwords are stored in the operating terminal’s Flash memory. These are the
default passwords that are used when the terminal is started up initially after a
download. At the same time, the passwords are stored in the operating terminal’s
RAM.
The passwords stored in the flash memory can be reactivated by writing to the
system variable FlashPasswd.

Every password (except for the master password = first password in the list) can be
edited from the terminal. For this process, the password to be edited is written to the
system variable MskchgPasswd first. The new password is then written twice to
the system variable ChangePasswd. If both entries for the new password are
identical, the password will become effective immediately; otherwise, a system
message will be displayed and the password reset.
Passwords are stored and compared as 11-character strings. The passwords are
entered with the Alphanumerical Editor.
Passwords are only globally programmable (not language-specifically).

4.4.3.3 Password Mask and Password Functionality

- It is possible to create a special mask which requests entry of a password. This
password mask is then displayed whenever an attempt is made to call up a
password-protected mask without first entering a password with sufficient au­thorization. When a password with sufficient authorization is entered into this
mask, the previously selected password-protected mask is called up once the
Data Release key is pressed. There are no restrictions with respect to the re­maining mask contents (texts, further variables, soft keys, etc.).

- You can specify for every mask separately whether the password protection is
to be reactivated after the mask is exited.

- For those cases where no valid password has been entered, an option to exit the
mask must be provided. The Cursor home key can be programmed to perform
this function, for example.

- If no such mask has been created to prompt for password entry, the operator will
be required to enter the password in masks specifically designed for this pur­pose.

- The entire password protection can be deactivated by setting the system vari­able PasswdInactive to the value 1. The operating terminal will then act as if all
masks were created with an edit and view level of 0. The system variable is
battery-backed, so deactivation will therefore still be in effect after the operating
terminal is restarted.

70

Standard Mode Section 4-5

4.5 Masks

In conjunction with the operating system, the term ‘mask’ always refers to the con­tents of one screen. The size of masks therefore varies from operating terminal to
operating terminal.
Masks with a specific functionality form the basic elements of the operator guid­ance. The first step when programming a mask is to specify its functionality. The
process of designing the operator guidance is greatly simplified by the restricted
number of different mask types.

The following mask types are available in the operating concept:

- Setup Mask (system mask)

- Start Mask (system mask)

- Password Mask (system mask)

- Main Mask (system mask)

- I/O Mask (user mask)

4.5.1 Mask Parameters

The number of mask parameters that is available for a specific mask depends on
the mask type. The mask parameters determine the functionality of the control keys
in the operator guidance. Any mask parameters which are not required may remain
unassigned. If no mask parameters at all are programmed, only the function keys
or external mask selection can be used to exit the mask in question.
The functionality of the control keys specified in the mask parameters is subject to
access control of the password system. This prevents unauthorized access to
masks via the control keys.
In addition to the control key functionality, the mask parameters also contain the
access level definition. The access level indicates the minimum value that a pass­word (view level, edit level) must have to be authorized to access a mask and edit
its values. The default value used for the access level is ‘0’ (meaning free access).
A selected Automatic Data Release option in the mask parameters will allow the
operator to supply input into the mask without having to press the Data Release key
first.
An option for automatic reactivation of the password protection is also available in
the mask parameters to ensure that the password has to be reentered when a
password-protected mask is called up again.

4.5.2 System Masks

System masks facilitate initial programming. They also get your system up and
running directly. This makes the initialization phase an integral part of the user
description. Any mask can be selected as a system mask. System masks are basi­cally I/O type masks with a few restrictions. These restrictions result from the op­erator-prompted initialization phase and the fact that communication to the con­troller is not yet established.

The system masks Setup Mask and Start Mask can not be accessed via external
mask selection!

71

Standard Mode Section 4-5

4.5.2.1 Setup Mask

Only terminal-specific parameters can be defined in the Setup Mask. This is be­cause

no communication takes place with the connected controller while the Star­tup Mask and Setup Mask are displayed. The external data release therefore has
no function. To protect data, a password must be assigned.

From the operator guidance, the Setup Mask and Startup Mask can be reached
through the function keys, provided they have not been assigned an access level.
After the masks are exited, however, the terminal is not reinitialized.

Examples of terminal-specific parameters:

- Printer interface settings

- Default contrast/default intensity setting of the display

- Date and time settings

- Activation of the download function.

4.5.2.1.1 Password Protection - Setup Mask

The Setup Mask is an exception with regard to password protection.
To password-protect the Setup Mask, the system variable MskchgPasswd must
be set up as the first variable which can be edited in the Setup Mask. A password
can be input regardless of the access level (with the exception of the access level

255).
For the setup mask, the access level applies to the edit level only, meaning that its
contents are always visible to the operator.

4.5.2.1.2 Function Without the Setup Mask

If the Setup Mask is not needed, its access level can be set to the value 255, thus
preventing access to the Setup Mask via the Start Mask (using the Data Release
key).

4.5.2.2 Start Mask

The Start Mask is displayed for around 5 seconds after the terminal is switched on.
This is a fixed time setting; the startup process can not be changed.
With regards to the mask design, the user can only design the text to be displayed in
the mask. Any combination of characters, character sizes and text attributes can be
chosen in the programming system for this purpose.
Only system variables can be output in the Start Mask. Variable input is not pos­sible due to the time restriction. While the Start Mask is displayed, the Setup Mask
can be called by pressing the Data Release key. However, this is not possible if the
access level for the setup mask is set to 255.

Some examples of information that may be chosen to be displayed in the Start
Mask are listed below:

- address for servicing

- machine type

- version number of the program

72

Standard Mode Section 4-5

4.5.2.3 Password Mask

The password mask is an I/O type of mask. The functionality is as illustrated in the
password description.

4.5.2.4 I/O Mask

As a basic type of mask, the I/O mask offers a broad range of functions - enough in
fact for configuring complete operator guidances based entirely on it.
I/O masks provide the following options:

- Selection of menus

- Definition of data formats

- Scaling of values

- Output of values once or cyclically

- Text display

- Message output

- Direct selection of up to five adjacent masks with the control keys

- Display of large mask contents over several screen pages

- Display of values in tables

Key Functions in the I/O Mask

Key: Cursor up Can be programmed freely to select adjacent masks
Key: Cursor down Can be programmed freely to select adjacent masks
Key: Cursor left Can be programmed freely to select adjacent masks
Key: Cursor right Can be programmed freely to select adjacent masks
Key: Cursor home Can be programmed freely to select adjacent masks.

Exits the I/O mask for the higher-level menu.
Key: Data Release Switches into the Editor and exits the Editor
Key: Enter Only has a function in conjunction with the Editor
Key: ?, Help Displays the help text specified for the mask for as long

as the key is held down

4.6 Variables

The number of valid variable types is determined by the connected controller. All
standard variable types which are commonly used are supported by the operating
terminals. The data type that is used also determines the valid range of values and
number of significant digits.

Variable Type Size Range of Values

Bit 1 bit [0, 1]
Byte 1 byte [-128 to +127]
Byte 1 byte [0 to 255]
Word 2 bytes [-32768 to +32767]
Word 2 bytes [0 to 65535]
Lword 4 bytes [-2147483648 to [phone]]

Standard Mode Section 4-6

4.6.1 Output Variables

Output variables are numerical or alphanumerical data stored in the memory of the
connected controller. The variables are retrieved from the controller whenever re­quired, and output on the display at the programmed location according to the
defined method of representation, formatting and scaling. Generally, a distinction
is made between displaying one-time variables (variables are transferred only
once and are then displayed) or at cyclic intervals (variables are continually up­dated while displayed). The character attributes that are available depend on the
display type of the operating terminal.

One-Time Output Variables or Cyclic Output Variables:

Pure output variables are transmitted by the controller

only once and are displayed
in the mask. This method offloads the communication process and is suitable for all
variables such as setpoint values, constant values and parameters that change
either rarely or never. All output variables can be displayed on a scaled and format­ted basis.
Cyclic output variables are used to display actual values, in other words values
which vary continually while a mask is displayed. The cycle time (and thus the
intervals at which the displayed actual values are refreshed) corresponds to the
polling time predefined by the user.

Data transfer between the operating terminal and the PLC can be offloaded
by using variables of the same data type only (data word, flag word, input
word, flag word) and by using continuous addresses within one mask.

Cyclic output variables can also be scaled and formatted. Note that the display of
floating point numbers requires more computing time when the values are scaled.
These will therefore not be displayed in ‘real time’. For this reason, the cycle times
selected here should be . 500 ms.
Also note that the larger the amount of cyclic data for transfer, the longer the re­sponse time to new values from the PLC. As a result, longer polling times are re­quired.

Formatted Output:

Formatting a numerical variable allows the display format of the variable to be
adapted to the output range of values. Formatting includes the number of digits to
be displayed, the number of post-decimal places (fractional digits) and whether
signs are to be used or not. The number of post-decimal places gives the operator
the impression that a division has been performed. A division is not actually carried
out, however. The variable in the controller must be available in the appropriate
(higher) resolution.

Example:
Actual value of a length in the controller:
Word variable Range of values 0 to 65535

Resolution 1/100 mm

Display of actual values on the operating terminal:
Display range 0.00 to 655.35 mm

74

Standard Mode Section 4-6

The output is in millimeters, so a conversion in the controller is not necessary. The
following format has been selected in the variable definition:
PLC address: Data type Word
Variable type: Decimal number (without sign)
Length: 6 digits
Post-decimal places: 2 digits

Selecting ‘with sign’ would cause the output to change as follows:

Display range -327.68 to 327.67 mm

Because of the sign, the output length has increased to 7 digits. The format spec­ified in the variable definition must be adapted accordingly.

Format Data type formatting scaling

Binary Bit, Byte, Word, Lword x ­Hexadecimal Byte, Word, Lword - x
Decimal Bit, Byte, Word, Lword x x
BCD Byte, Word, LWord - x
Floating point Lword x x
Selection text Bit, Byte, Word x ­Text ext. ASCII font - -

The format corresponds to scaling without the need for calculation.

Scaled Output

When a variable is scaled, its range of values can be adapted to the operator guid­ance. Scaling applies to data input and output. The operands can be entered in the
programming software.

Scaling for integers:

Operand Range of values

Factor -32768 to +32767 (excluding the value 0!)
Divisor 1 to +32767
Summand -32768 to +32767

The operands factor and divisor must be .0!

Scaling for floating point numbers:

Operand Range of values

Factor +/-999999999,99999999 (excluding the value 0!)
Divisor +/-999999999,99999999 (excluding the value 0!)
Summand +/-999999999,99999999

The operands are stored in IEEE-format
The variable also retains its entire value range for formatting.

75

Standard Mode Section 4-6

Formula for Scaling the Output:

Scaling is always performed on the variable in the operating terminal. Through
scaling, the measured values collected in the controller are adapted to the operator
guidance. The output representation is determined by

formula 1

only. Unlike the
factor and divisor, the summand (representing an offset) can be set to the value 0.
Before a variable or constant is output on the display, it is converted as follows:

PLC value × Factor

Terminal value = + Summand

Divisor

Fig. 3: Formula 1

Output Representation Types:

Certain types of variables can be recognized more easily if they are displayed in
their own specific format. A type-specific representation makes interpretation of the
variable content easier. For this reason, a wide range of representation formats is
provided.
Examples:

- Input statuses of an input module Binary representation

- Filling level of a container Bar (bar chart)

- Temperature Curve (line graph)

- Valve states Graphics showing valves

Example of a coded text used for outputting an end position condition:

Binary Hex Decimal Selection Text (Coded Text)
0 00 0 Not in end position
1 20 32 In end position

Representation With Leading Zeros:

The option of displaying leading zeros can be used in conjunction with every in­teger. Leading zeros are required in particular for displaying dates and times and
hexadecimal or binary formats. The ‘Display Leading Zeros’ option can be selected
in the variable definition.

Representation without Representation with

Leading Zeros Leading Zeros
Binary Number 10 0101 0010 0101

76

Standard Mode Section 4-6

4.6.1.1 ‘Decimal Number’ Representation

The decimal representation of numbers is the most frequently used representation
method.
The operating concept differentiates between the following decimal number types
of representation: Standard, Timer, Counter and BCD-Format.
Decimal representation includes integers and floating point numbers.

4.6.1.1.1 ‘Standard’ Variable Type

The positional significance of the displayed positions increases from right to left.
Leading zeros or the decimal point can be displayed as an option. Decimal repre­sentation is suitable for the data types Bit, Byte, Word and Lword. The maximum
length depends on the data type. There are no blanks between the characters. In
the controller, this variable is in the binary format or special timer or counter for­mats.

4.6.1.1.2 ‘Timer’ Variable Type

The variable type Timer has a special function only when used in combination with
Simatic S5 controllers.
The kind of formatting of the variable type Timer depends on the memory area of
the PLC where the value was read. If the value is read directly from a timer word, the
10 bit binary time value contained in it and the 2-bit time base are converted to the
time value to the base 10 ms. If read from a different memory area, i.e. data word
(DW), flag word (MW), input word (EW) or output word (AW), it is then assumed that
the value is BCD-coded (3 digits BCD-code and 2 bit time base). This value will also
be converted to a time value to the base 10 ms.
The resulting time value to the base 10 ms can now be formatted in the same way
as a fixed point number, i.e. use of post-decimal places is possible and scaling can
be applied.

Example:
A setpoint value is entered on the operating terminal: Address MW100
The current actual value is displayed on the operating terminal:Address MW200

Representation Input
Variable:

Decimal Number / Timer / 7 Digits / 2 Post-Decimal

Places / Factor 1 /Divisor 1 / Summand 0
Representation Output
Variable:

Decimal Number/ Timer / 6 Digits / 1 Post-Decimal

Place/ Factor 1 / Divisor 10 / Summand 0

The command sequence

L MW 100
SI T 1

has caused the BCD-coded time value to be loaded into flag word 100.

77

Standard Mode Section 4-6

The command sequence

LC T 1 (Load current time value as a BCD-number)
T MW 200

now causes the current time value to be loaded into flag word 200. Before being
output, the operating terminal reads this value as a BCD-coded time value and
interprets it.
For this process, the time value is converted to the time base 10 ms first and is then
scaled.
The example lists the output values with one post-decimal place (fractional digit).
This produces the following to be displayed on the operating terminal:

Input Value Output Value Resolution KT Values (S5)

0000,01 to 0000,09 0000,0 to 0000,0 0,01 s 001.0 to 009.0
0000,10 to 0000,99 0000,1 to 0000,9 0,01 s 010.0 to 099.0
0001,00 to 0009,99 0001,0 to 0009,9 0,01 s 100.0 to 999.0
0010,00 to 0099,90 0010,0 to 0099,9 0,1 s 100.1 to 999.1
0100,00 to 0999,00 0100,0 to 0999,0 1 s 100.2 to 999.2
1000,00 to 9990,00 1000,0 to 9990,0 10 s 100.3 to 999.3

The resolution and as a result, the precision of the input and displayed values can
be influenced by modifying the post-decimal places and scaling.

4.6.1.1.3 ‘Counter’ Variable Type

The variable type Counter can only be used in conjunction with controllers that
support this variable type. This will be explained in more detail using the variable
type Counter in combination with the Siemens S5 as an example.

A Dual-coded count value, 0 to 999
B Edge trigger flag for setting, releasing, counting up and counting down
C Auxiliary flag for queries

Fig. 4: Structure of the counter word with the Siemens SIMATIC S5-115U

The kind of formatting of the variable type Counter depends on the memory area of
the PLC where the value was read. If read directly from a counter word, the 10 bit
binary count value contained in it will be displayed directly, so conversion is not
necessary.
If read from another memory area, i.e. data word (DW), flag word (MW), input word
(EW) or output word (AW), it is assumed that the value is BCD-coded (3 digits
BCD-code). The value will then be converted to a binary count value first.
The resulting binary count value can then be formatted in the same way as an
integer, i.e. scaling is possible.

78

Standard Mode Section 4-6

4.6.1.1.4 ‘BCD-Number’ Variable Type

The BCD format is partially used to represent numbers in the PLC. This output is
required in special cases. The positional significance of the displayed digits in­creases from right to left. The numbers 0 to 9 are used for the representation;
leading zeros can be included optionally. The BCD mode of representation is suit­able for the data types Byte, Word and Lword. The length is limited to a maximum of
8 digits. There are no blanks between the characters. The variable value is stored

4.6.1.2 ‘Alphanumerical’ Representation

In the alphanumerical mode of representation, ASCII strings are read from the
controller in byte format and are represented on the display. The number of charac­ters which can be displayed depends on the capabilities of the type of terminal
involved. One display line is the maximum permissible length for a variable; longer
texts are truncated. The address in the variable list indicates the beginning of the
character string. A definition of the variable size is

not included and is not neces­sary. The alphanumerical representation provides another means of editing mask
texts during runtime.

4.6.1.3 ‘Selection Text’ Representation

In the Selection Text mode of representation, a text string is assigned to a numer­ical value.
This allows two different tasks to be performed:

1. visualization or selection of statuses by means of text strings

2. change of mask.

An example of using a one-line selection text is the option of selecting the parity for
a serial interface.
In this case, the text list will contain three entries:

Value Text
0 No Parity
1 Odd
2 Even

A variable (ComParityA / ComParityB) is created in the mask.
Only these three options are selectable on the operating terminal by means of the
Standard or Mix-Mode Editor; invalid inputs are therefore prevented.

79

Standard Mode Section 4-6

Multiple-line selection texts are primarily used for menu control. Unlike one-line
selection texts, multiple-line selection texts display the text list either in full or in
part. If the value for the selection text field height is less than the number of text
elements to be displayed, the cursor keys can be used to scroll through the text
elements. After the final text list entry is reached, the selection proceeds with the
first entry.
To indicate that a text is selected, the entire selection text line is represented in the
inverse format.
With the representation type Selection Text, text lists are also used to assign mask
names to the mask numbers:

Value Text
10 Machine parameters
20 Serial message mask
30 Status messages
40 Message configuration
50 Interface parameters

A variable (NewMask) of the type Selection Text is created in the Main Mask with
the maximum height of 5 lines and a length of 25 characters. The values in the text
list and the mask numbers must match.
One of these entries can then be selected from the selection field displayed on the
operating terminal: the desired mask is then displayed.

4.6.1.4 ‘Selection Image’ Representation

In the Selection Image mode of representation, an image (pixel graphic) is as­signed to a numerical value. This image is assigned in an image list. The image list
is linked to the variable whose values are to be represented as images. In this way,
language-independent visualization of operating states, inputs and outputs, etc. is
possible.
Numbers may be freely assigned to the images. They need not necessarily be
contiguous or sorted in a consecutive order. In addition, a default image exists for
every image list which is displayed, whenever the variable assumes a value that
does not exist in the image list. The images used are cut to the size that applies to
the output format. This representation is limited to bits, bytes or words. Selection
image variables can be both displayed and edited using the +/- key (as with the
Selection Text Editor). Any modifications that are made are directly transferred to
the controller.

The example below illustrates how images are assigned to numerical values:

Value Image Name
120 Symbol1
34 Symbol2
7 Symbol3
1201 Symbol4

80

Standard Mode Section 4-6

The names for the images represent the images in the image list. The actual list will
look something like this:

This image list has been defined with four entries. The graphic selected by the
controller will be displayed.

All of the images in an image list should have the same output size to ensure that
they overwrite (overlap) each other completely. An I/O mask can contain multiple
selection image variables. These selection image variables can be of the types:
one-time output variable, cyclical output variable, or input variable. When the cycli­cal output of selection images (‘animation’) is chosen, it must be remembered that
the rate of change will be slow due to the limitations of the hardware performance.
The more images that are output, the smaller the output performance. The selec­tion image variable should therefore mainly be used for switching states or nearly
static processes.

4.6.1.5 ‘Floating Point Number’ Representation

The rules that apply to the Floating Point Number mode of representation are basi­cally the same as those applying to the representation type Decimal Number ­variable type Standard. The only difference is that with this representation type, the
factor that is used to achieve scaling can be a floating point number; a divisor is
therefore not required. With floating point numbers, the reciprocal value can also
be generated, before the value is displayed.
Not every controller type supports the floating point format. There are different
floating point formats available for processing in the controller (for example, the
IEEE format).

4.6.1.6 ‘Hexadecimal Number’ Representation

The hexadecimal representation of numbers is frequently used to display address­es when the PLC is programmed. This format is aimed for use by more experienced
operators! The positional significance of the displayed digits increases from right to
left. Numbers are expressed by the characters 0 to 9 and A to F. Only capital letters
and leading zeros are used for representation. The hexadecimal representation is
suitable for the data types Byte, Word and Lword. The length is limited to a maxi­mum of 8 digits. There are no blanks between the characters.

4.6.1.7 ‘Binary Number’ Representation

The binary format permits the representation of single bits, bytes, words or Lwords.
The value for the ‘length’ entered in the variable definition corresponds to the num­ber of bits to be represented. Counting always begins with bit 0. The number of
blanks indicates how many gaps (spaces) are inserted between each bit. Output is
always in the horizontal position. The direction of the positional significance can be
set in the variable definition.

Bit 3 Bit 2 Bit 1 Bit 0
0100Direction = 76543210
Bit 0 Bit 1 Bit 2 Bit 3
0010Direction = 01234567

0100 Blanks = 0
0100 Blanks = 1
0100 Blanks = 2

4.6.1.8 Bar Representation

Variables in I/O masks can be represented as bars. They can be programmed to be
either horizontal or vertical. The bars can start at a reference point (e.g. in the
center of the display) and extend in both the positive and the negative direction.
The range of values of the bars can be defined by specifying the upper and lower
limit (corner values). The bars are represented on the terminal with the aid of four
different graphical objects, the simplest of which is a fill pattern. Separate fill pat­terns can be specified for:

- the empty part of the bar

- the filled-in bar

- the ‘lower limit exceeded’ bar

- the ‘upper limit exceeded’ bar

The programming software includes seven default fill patterns for representing
bars on the operating terminal. The other, above-mentioned graphical objects can
also be used to design your own fill patterns and shapes.

Fig.5: Different forms of bar representation

82

Standard Mode Section 4-6

Bar charts can be output once only, cyclically or after defined events (event-con­trolled). They are used purely to indicate actual values.

The range of values for outputs extends from -32768 to +32767.

If your mask contains several bars, you should address the variables such
that they can be transferred contiguously.

Each bar varies between a lower limit and an upper limit. Outside these limits, it
changes to the predefined fill pattern for Upper or Lower Limit Exceeded.

Possible applications:

- Vertical and horizontal trend displays

- Visualized monitoring of limit values

- Histograms

- Filling-level indications

Example of a filling-level indication:

Bitmap:
Lower Limit Exceeded

Intermediate V alueBitmap:

Lower Limit

Bitmap:
Upper Limit

Bitmap:
Upper Limit Exceeded

Fig. 6: Example of a filling-level indication

The bar mode of representation always means a slower output rate. Each bar
therefore always corresponds to an integer multiple of a character. The smallest
possible bar is equivalent in size to a single character, while the largest bar covers
the entire display. The bars ‘grow’ one pixel at a time.

4.6.1.9 Curve Representation (Trendline)

The curve mode of representation permits value tables to be output as dotted lines.
A ‘curve’ variable must be defined in a mask in order to represent a curve. The size
of the curve is determined by its length and height. If a coordinate system is requir­ed, it can be displayed with the aid of background images.
The address of the curve variable represents the start of a value table in the PLC.
Each value in the table describes one pixel on the curve. The graphical repre­sentation of the value table resembles that for cyclic output variables.

Examples of a variable time history:

- Output of one-time processes

- Memory function of a point recorder

- Filling-level curves

A curve is limited by the following parameters:

- Maximum height: Height of the display

- Maximum width: 54 pixels per curve variable

83

Standard Mode Section 4-6

If you need a width of more than 54 pixels, you can output several curves directly
adjacent to one another.

Fig. 7: Example of a curve representation

The height information, in other words the variable values, is read from the controll­er in a contiguous field by means of one read job. The height information in the field
element with the starting address

(address + 0)

is displayed on the far left. All

subsequent height information (

address + n

) is shifted one pixel position to the
right. The curve height information is refreshed cyclically.
The output is thereby deleted and written again one pixel at a time.
Only two parameters are required to represent a curve:

- Curve width as a multiple of the character width (normal font)

- Curve height as a multiple of the character height (normal font)

4.6.2 Input Variables

Input variables, when displayed for the first time (when the mask is activated), are
treated in the same way as one-time output variables, i. e. the same representation
options are available. This includes the scaling effect.

Scaling is performed on the value in the PLC.

Input variables can be modified in the terminal by means of Editors. Their function­ality is determined by the type of Editor that is selected.
The Editors that are supported for variable input are the same as those supported
for variable output. Editing of the variables is subject to certain conditions which
must take into consideration by the user when creating the project, such as the
password protection and the external data release, for example.
The following must be observed when entering timers and counters:

Timer

When writing to a timer variable, any scaling that may have been performed is first
reversed to give the time value to the base 10 ms again. The BCD-coded value is
then calculated so that the lowest possible time base is used.

Avoid writing to a timer word in the PLC, as this has uncontrolled results on
the control bits.

84

Standard Mode Section 4-6

Counter

When writing to a counter variable, any scaling that may have been performed is
first reversed. The BCD-coded value is then computed and transferred to the PLC.

Avoid writing to a counter word in the PLC, as this has uncontrolled results
on the control bits.

Formula for Scaling Input Values

Input values transferred by the PLC are processed according to

formula 1

before
being displayed. After the values have been edited, they are processed in accord­ance with the inverse function (

formula 2

) before being transferred back to the PLC.
The inverse function will automatically be generated in the terminal. Operands
must be defined by the user on the basis of the values in the PLC including the input
value.

Input value × Summand

PLC value = × Divisor

Factor

Fig. 8: Formula 2

During conversion, the last digit is automatically rounded. This must be kept in mind
when defining the upper limit.

(Input value × Factor) , (Pos. Upper Limit - Divisor / 2)

Fig. 9: Formula 3

Plausibility Check

A plausibility check is performed on all input variables. As a part of this check, the
entered value is validated against the upper and lower limits specified in the vari­able definition. System messages are generated if the entered value is outside
these limits. In this case, the invalid value will not be transferred to the controller
and the previous (valid) value will be retained.

If the system message texts ‘Value too large’ and ‘Value too small’ are deleted, the
following applies:

- if the value drops below the limit, the value corresponding to the lower limit is

used

- if the value exceeds the upper limit, the value corresponding to the upper limit is

used.

A system message is not output during this process.

Help Text for Input Variables

A screen-sized help text can be created for each input variable. This help text can
be displayed in the Editor by pressing the Help key. Important information to be
inserted in a help text may include the upper and lower limits, the impact of vari­ables on the process to be carried out, or any interactions with other variables.

If a variable-specific help text is not defined, the default help text will be displayed
instead. This is also a screen-sized text which can be edited in the programming
software. If a default help text is not defined, a blank mask will be displayed.

85

Standard Mode Section 4-6

4.6.3 System Variables

System variables can be used to control terminal-internal functions.
System variables can be referenced to function keys and soft keys. They can also
be used in masks as normal variables for input and output processes.

The following applies if a system variable is linked to a function key or soft key:

- do not link a change of mask function and a system variable to the same key

- it is not necessary that the same function key or soft key is used to set (1) and
reset (0) a system variable

- jogging mode is obtained by using the same function key or soft key to set (1)
and reset (0) a system variable.

Do

not include the names of system variables in the variable list. If the name of a
system variable is referenced to a PLC address, it will loose its terminal-internal
function.
The following subchapters list the system variables, organized into separate
groups of functionality, and describes their functions.

4.6.3.1 Basic Functions

IntEraseEprom

Allows the user description to be erased from the Flash memory and prepares the
terminal for a new download via interface channel SER2. There will be no commu­nication with any connected PLC during this process. Writing of a ‘1’ to this variable
erases the user description unconditionally. Subsequently, the variable is automat­ically reset to ‘0’.
