The TD 200 is a text display device that displays messages enabled by the
S7-200 CPU. You do not have to configure or program the TD 200. The only
operating parameters stored in the TD 200 are the address of the TD 200, the
address of the CPU, the baud rate, and the location of the parameter block. The
configuration of the TD 200 is stored in a TD 200 parameter block located in the
variable memory (V memory) of the CPU. The operating parameters of the
TD 200, such as language, update rate, messages, and message-enabled bits, are
stored in the TD 200 parameter block in the CPU.

Upon power-up, the TD 200 reads the parameter block from the CPU. All of the
parameters are checked for legal values. If everything is acceptable, the TD 200
starts actively polling the message-enabled bits to determine what message to
display, reads the message from the CPU, and then displays the message.

Configuring the TD 200

2.1 Starting the STEP 7-Micro/WIN TD 200 Configuration Wizard

STEP 7-Micro/WIN provides a “wizard” that makes it easy to configure the
parameter block and the messages in the data memory area of the S7-200 CPU.
The TD 200 Configuration Wizard automatically writes the parameter block and
message texts to the data block editor after you finish choosing the options and
creating the messages. This data block can then be downloaded to the CPU. For
detailed information about the TD 200 parameter block and message formats, see
Appendix D.

This chapter contains the procedure for creating a sample TD 200 application. Use
the instructions in this example to create a TD 200 parameter block and three
messages using the TD 200 Configuration Wizard. The first message is text only.
The second message contains both text and embedded data. The third message is
a text message that requires acknowledgement by the operator.

The example also shows how to use the function keys to enable a message and
how to use the acknowledge- and edit-notification bits within your program.

To open the wizard, select the menu command Tools > TD 200 Wizard... as
shown in Figure 2-1.

To navigate through the dialog boxes of the wizard, click on “Next>.” At any time
during the procedure, click on the “<Prev” button to go back to a previous dialog
box if you need to change or review any of the parameters you have defined. In
the final dialog box, click on “Finish” to validate and save the parameter block and
close the wizard.

You can view the configured parameter block and messages by opening the
STEP 7-Micro/WIN data block editor.

The first dialog box in the TD 200 Configuration Wizard allows you to select the
language and character set. Use the drop-down list box shown in Figure 2-2 to
select the language in which the TD 200 menus display. (This selection does not
affect the text of the user messages displayed on the TD 200.) Use the option
buttons to select the standard character set or the alternate character set. The
alternate character set allows you to display bar graph charts on the TD 200.

Enabling Time-of-Day, Force Function, and Password Protection

The dialog box shown in Figure 2-3 allows you to enable Menu mode options and
set an edit password.

The Time-of-Day (TOD) and force menu selections allow you to selectively enable
the TOD Clock menu and/or the Force menu. Once a selection is enabled, you are
allowed to access that menu in the TD 200. If the menu is not enabled, it does not
appear in the TD 200 Menu mode.

The password protection selection allows you to enable a four-digit password (from
0000 to 9999). The password controls the ability of the operator to edit variables
embedded in a message and to access the Menu mode. If you enable password
protection, a field appears in the dialog box for you to set the password. This
password is not the CPU password and it is stored in the TD 200 parameter block.

For this example, use the option buttons to select the modes shown in Figure 2-3.
Set 1111 as your password.

TD 200 Configuration Wizard

Configuring the TD 200

You can configure your TD 200 to allow the user to set the Time of Day clock in the
CPU, and to Force I/O in the CPU. You can also passwordĆprotect these options, so

Specifying Function Key Memory Bits and Display Update Rate

The dialog box shown in Figure 2-5 allows you to specify the marker byte
(M memory) address for the TD 200 function keys and determine the update rate
of the TD 200.

You must reserve eight bits of marker memory (M bits) for the TD 200 to use when
a function key is pressed. Your program can inspect these bits and take an action
when a key is pressed. One M bit is set by the TD 200 each time the
corresponding function key is pressed. Always reserve an M Area address even
when your program does not utilize function keys. Valid address values for specific
CPUs are defined in the

Manual

.

Warning

!

The TD 200 sets an M bit each time a function key is pressed. If you do not intend to use
function keys, and so do not assign an M byte address for function keys, the TD 200
defaults to byte M0 for the function keys. If your program uses bits in M0, and a user
presses any function key, the TD 200 sets the corresponding bit in M0, overwriting the
value assigned to that bit by your program.

Inadvertent changes to M bits could cause your program to behave unexpectedly .
Unpredictable controller operation could cause death or serious injury to personnel, and/or
damage to equipment.

Always reserve an M area address, even when your program does not utilize function
keys.

Figure 2-4 shows a referenced byte (MBn) and shows which bit of the byte is set
by each function key.

The update rate selection determines how often the TD 200 polls the S7-200 CPU
for messages to display. The actual update time may be slower than the time that
you select because of the size of the message, the processing required, or
network traffic.

For this example, select M0 and As fast as possible as shown in Figure 2-5.

TD 200 Configuration Wizard

The TD 200 has 8 function keys (F1 through F4 and SHIFT F1 through SHIFT F4)
that are used to set memory bits in the CPU. You must reserve eight bits of memory
(M bits) for the TD 200 to set when a function key is pressed. One M bit is set by
the TD 200 each time the corresponding function key is pressed.

Which byte of M memory would you like to reserve for the TD 200?

The dialog box shown in Figure 2-6 allows you to set the message size and
quantity of messages. Select a 20- or 40-character size for your messages. The
TD 200 supports up to 80 messages. Enter a number from 1 to 80 in the text field
to specify the number of messages you want to create.

For this example, choose three 40-character messages.

Specifying Parameter Block Address, Message Enable Address, and Message Location

The dialog box shown in Figure 2-7 allows you to specify starting addresses for the
parameter block, the message enable flags, and the messages.

The TD 200 looks for a parameter block in the V memory of the CPU. The default
location for the parameter block is VB0. The default location can be changed. See
Section 3.8 and Section D.1 for information about placing the parameter block at
other locations.

The starting byte for the message enable flags defines the location in V memory at
which the message enable flags begin. There are eight message enable flags
stored in each byte. Whole bytes must be allocated for message enable flags even
if all the bits are not used. The text in the dialog box shown in Figure 2-7 specifies
how many bytes of V memory are needed for message enable flags based on the
number of messages you set in the previous (Figure 2-6) dialog box.

The starting byte for message information defines the starting location of the first
message in V memory. Messages are placed consecutively in memory. Either 20
or 40 bytes are reserved for each message based on your selection in the previous
dialog box (Figure 2-6). The text in the dialog box shown in Figure 2-7 specifies
how many bytes are required for messages.

Values for the parameter block, enable flags, and message information starting
addresses are CPU specific. See the

System Manual

for the valid address ranges for specific CPUs.

SIMATIC S7-200 Programmable Controller

For this example, set the parameter block starting byte to 0, the enable flags
address to 12, and the message information starting address to 40 as shown in
Figure 2-7.

Creating A Text-Only Message

The dialog box in Figure 2-8 allows you to enter the text for a TD 200 message.
The dialog box also shows you the starting address of the message (Message
beginning address). It also shows you the address of the message-enabled bit for
this message. Your program uses this message-enabled bit to control the display
of this message on the TD 200. Setting the message-enabled bit to a 1 causes the
TD 200 to read and display this message.

For this example, type in your message as shown in Figure 2-8. This is a text-only
message, so there is no embedded data. Since there are two more messages to
configure in this example, click on “Next Message >” to continue.

Embedding Data Values in a Text Message

You can place a data value within the message that displays on the TD 200. In
order to display a data value, you must reserve space in the message for the data
value and for format information. The format information tells the TD 200 how to
display and edit the data value. The format information requires the space of two
characters in your message. Word data values require the space of two characters
in addition to the format information (four characters total). Double word or real
(floating point) values require the space of four characters in addition to the format
information (six characters total).

When you insert a data value into a message, you must be sure there are enough
characters to contain the format information and the embedded data value on the
current line of the display. For example, if you insert a word value, (two characters
for the word value and two characters for the format information), you must allow
at least four spaces between the starting position of the embedded data value and
the end of the current message line.

The right-most character of an embedded data value serves as the anchor point
for that value in the TD 200 display. Data values are always right justified to that
anchor point within messages on the TD 200 display. As a data value grows in
magnitude, it utilizes more spaces to the left of the anchor point and can begin to
use the spaces occupied by the message text. Be sure to leave sufficient space
between the end of your text and the anchor point to allow for the expected range
of the data value.

The number of display characters used to display a value varies with the size of
the value. This number of characters required to display a number is not the same
as the number of characters used to store the embedded data value in the
message. The number of display characters required depends on the range of
values for that number in a specific application. See Table D-1 for examples of the
number of display characters required for different display formats.

The TD 200 displays all values as decimal numbers. Positive signed values are
displayed without a sign. Negative signed values are displayed with a leading
minus sign. Unsigned values are displayed without a sign. A leading zero is used
for all fractional numbers (for example, 0.5). Real numbers are displayed with the
number of decimal places you specify. The value is rounded to the specified
decimal place.

Formatting the Embedded Data Value

Figure 2-10 shows the Embedded Data dialog box. This dialog box allows you to
specify the data type, format, and display characteristics of an embedded data
value. You can also select whether or not the message requires acknowledgement,
whether the data value can be edited, and whether or not editing requires a
password. Some options depend on the selections you make and do not appear
when the dialog box opens.

The data format selection defines the size of the data value embedded in the
message:

 Select “None” when a message requires acknowledgement but there is no

embedded data value to be displayed on the TD 200.

 Select “Word“ when the embedded data value is an integer. A word or integer

value requires the space of two characters within your message to hold the
data value.

 Select “Double Word” when the embedded data value is a double word or a real

(floating point) value. A double word or real value requires the space of four
characters within your message to hold the data value.

The display format selection tells the TD 200 whether the data value is signed or
unsigned. The TD 200 uses this information when editing the data value. Signed
values may be either positive or negative numbers. Unsigned values are restricted
to positive numbers.

The selection for digits to the right of the decimal provides scaling for the display of
the data value. If the data value is an integer, this selection allows you to scale the
integer value for display by specifying the location of the decimal point. For
example, if the data value is equal to 123 and you select 1 digit to the right of the
decimal, the TD 200 displays 12.3.

The Embedded Data dialog box contains a check box to require acknowledgement
of the message. If a message requires acknowledgement, it flashes on the TD 200
display until the operator presses ENTER. The dialog box also contains a check
box for allowing editing of the data value. If this box is selected, the operator can
edit the embedded data value. If the box is not checked, the data cannot be edited.

The Embedded Data dialog box also lists the address of the data value within the
message. The user program uses this address to write the data value in the
message.

For this example, make the selections shown in Figure 2-10 and click “OK.”

This variable displays as a real number which requires a double word data format.
After you select “Double Word,” the Display Format area allows selection of a real
(floating point) number format. For real numbers, the field entitled Digits to the right
of the decimal defines the fixed decimal location of the real number in the TD 200
display. The TD 200 rounds a real number to the specified decimal place. For
example, if the real number value is 123.456 and you select 2 digits to the right of
the decimal, the TD 200 displays this value as 123.46.

In this example, this variable should be editable by the user. Select the check box
that allows the user to edit the data. Once the edit-allowed selection has been
made, two new fields appear in the Embedded Data dialog box.

The Edit Notification Bit field specifies the location of a bit which the TD 200 sets to
1 whenever the data value is edited and written to the CPU. The CPU program
uses the edit-notification bit to recognize when an editable data value has been
changed. The program can then read and make use of the edited value. The user
program is responsible for resetting this bit to 0.

The password-protected check box asks you if you wish to require a password for
editing this data value. If checked, the operator must enter a password before

Creating a Message That Requires Acknowledgement

To ensure that important messages are displayed and acknowledged by an
operator, you can configure a message to require acknowledgement. This
message flashes when displayed on the TD 200. The operator must press the
ENTER key on the TD 200 to acknowledge the message.

When the message is acknowledged, the following things happen:

 The message stops flashing.
 The acknowledge-notification bit is set in the CPU.
 The message-enabled bit for this message is reset in the CPU.

To force acknowledgement of a message, embed a format word in the message.
The format word tells the TD 200 how to display the message. The format word
uses two contiguous characters within your message. Since there is no data
associated with this format word, the format word can be placed anywhere in your
message (not just at the end). The format characters appear as blank spaces on
the TD 200 display.

For this example, enter the message text as shown in Figure 2-14. Place the
cursor on the 39th digit position and click on “Embedded Data...” button below.

Operating the TD 200

3.1 Using the Display Message Mode

The Display Message mode is the default operating mode of the TD 200. When
you power up the TD 200, the TD 200 enters the Display Message mode and
remains in this mode until you enter the Menu mode. The TD 200 returns to the
Display Message mode from the Menu mode if you do not press any keys for one
minute.

Figure 3-1 shows you the default message of the Display Message mode.

Figure 3-1 Display Message Mode

Functions Available

In the Display Message mode, you can perform the following functions:

 Scroll through enabled messages
 Edit values
 Acknowledge a message

There is no cursor on the display in the Display Message mode. The cursor is only
displayed when a key is pressed. To show the cursor, you must press either the
UP or the DOWN key.

If there are more messages enabled than the display can show, the TD 200
displays the one or two (based on message size) highest priority messages and
places a flashing DOWN arrow at the right-most character of the second line. This
indicates that there are more messages available for display. Use the following
steps to view additional messages:

1. Press the DOWN arrow. The TD 200 displays the next lower priority
message(s).

2. Press the UP arrow. The TD 200 displays the next higher priority message(s).

3. Press any key (except the UP or DOWN arrows). The TD 200 exits the scrolling
mode.

SIMA TIC TD 200 Operator Interface

C79000-G7076-C205-05

Editing a Value

You can use the TD 200 to modify variables embedded in the messages. The
operator uses the arrow keys and the ENTER key to select a message and to edit
variables.

Use the following procedure to edit a variable:

1. Select a message by pressing either the UP or the DOWN arrow key to place

2. Press ENTER to move the cursor to the least significant (right-most) character

3. If the variable is password-protected, enter the 4-digit password at the prompt

4. Press either the UP or the DOWN arrow key to increment or decrement the

Operating the TD 200

the cursor on the first character of the desired message.

of the first editable variable in the message.

and press ENTER.

variable. (Pressing and holding either the UP or the DOWN key accelerates the
increment or decrement operation.)

– To move the cursor to the next digit position, press either the SHIFT UP

(left) or the SHIFT DOWN (right) keys.

– To reset the variable to 0, press the SHIFT ENTER keys.

5. Press ENTER to write the updated variable to the CPU.
At the same time the updated value is written to the CPU, the corresponding

edit-notification bit is set to 1.

If you do not edit the message variable, or abort the edit by pressing ESC, the
message-enable bit is not cleared by the TD 200. The message-enable bit is
cleared by the TD 200 only when you write the last editable variable to the CPU.

The UP and DOWN arrows that indicate higher and lower priority messages, if any
are present, are disabled while an edit is in progress. These functions are restored
when the edit is completed or aborted.

If there are more editable variables in the message, the cursor moves to the next
variable. After all of the variables in the message have been edited, the
message-enable bit for the message is cleared in the CPU. The message is then
removed from the display on the next update cycle.

Note

Due to restrictions in the format used to store real (floating-point) numbers in both the
S7-200 CPU and the TD 200, the accuracy of the number is limited to six significant digits.
Editing a real number with more than six digits may not change the value of the variable, or
may cause other digits within the number to change:

 Changing the least significant (right-most) digit of a real-number variable with

more than six digits may have no effect. For example: if you try to change the
“9” in “1234.56789”, the value of the variable does not change.

 Changing the most significant (left-most) digit of a real-number variable with

more than six digits may cause other (less significant) digits in the variable to
change.

SIMA TIC TD 200 Operator Interface
C79000-G7076-C205-05

3-3

Operating the TD 200

You can abort an edit at any time by pressing ESC. This causes the TD 200 to
reread the message from the CPU and to display the variables from the CPU.
When the edit session is aborted, any values that have already been sent to the
CPU (by pressing the ENTER key after modifying the value) are displayed; any
value that was modified but not saved is overwritten by the previous (original)
value.

When you abort an edit, the cursor returns to the left-most character of the
message. (The message is not removed from the display until all of the edits are
completed and written to the CPU.) If the message was configured for
acknowledgement, the message starts to flash again, since the edit was not
completed.

Note

An edit is automatically aborted if you do not press a key after one minute.

Acknowledging a Message

Some messages require acknowledgement. To acknowledge a message, move the
cursor to the first character of the message and press ENTER. Messages requiring
acknowledgement are not replaced on the display until you acknowledge the
message.

Messages that do not require acknowledgement or editing are replaced on the
display if a higher priority message is enabled by the S7-200 CPU. For more
information on acknowledging a message, see Section D.5.

3.5 Forcing I/O

The Force I/O menu is only available if the force-menu enable is set in the TD 200
configuration that is stored in the CPU. The Force I/O menu allows you to force
inputs, force outputs, or unforce all inputs and outputs.

In the S7-200 CPU, you can establish password protection for the force I/O
function. The TD 200 reads the password protection level from the CPU. If the
force function is password protected, the TD 200 asks you to enter the CPU
password.

Note

The CPU password restricts editing of the force information in the S7-200 CPU. This
password is different from the password protection offered by the TD 200, which restricts
the editing of variables that are embedded in a message.

3.7 Releasing the Password

The Release Password option only appears if you have defined a password for the
TD 200.

The Release Password option allows the operator to end or pause an editing
session and to return the TD 200 to password protection. The password must then
be reentered before any editing is allowed.

The TD 200 also has a 2-minute time-out feature which automatically releases the
password, thereby restoring password protection. If the keypad is inactive (no keys
are pressed) for 2 minutes, the TD 200 prompts the operator to enter the password
again before editing.

Note

The Release Password option affects only the password protection offered by the TD 200,
which restricts the editing of data values that are embedded in a message. The Release
Password option is set in the parameter block for the TD 200. The Release Password
option does not affect the CPU password that restricts the editing of a user program
running on an S7-200 CPU.

Creating Sample Programs

This chapter provides sample programs that can be used for understanding how
the TD 200 performs various tasks.

The first program demonstrates how several variables can be placed on one
TD 200 display using ASCII text. A TD 200 and a CPU 214 are used to create a
clock. The second program illustrates the bar graph character set.

4.1 Using a Text Message to Create a Clock for a CPU 214

Creating a Sample Program

The following figures show a sample program that you can enter. This program
uses a text message to create a clock using a TD 200 and a CPU 214. The text
message is created using the Hex To ASCII (HTA) command and the result of the
conversion is placed into the proper V memory locations to produce a date and
time display. The display shows the date and time as:

month–day-year hour:minute:second

Using the STEP 7–Micro/WIN TD 200 Configuration Wizard

To create the parameter block and messages for the TD 200, you use the TD 200
Configuration Wizard. Select the menu command Tools > TD 200 Wizard... as
shown in Figure 4-1.

Use the instructions on the following pages to create a TD 200 parameter block in
V memory. To advance to the next dialog box, click on “Next>.” At any time in the
procedure, you can click on the “<Prev” button to go back to a previous dialog box
if you need to change or review any of the parameters you have defined.

At the end of the procedure, click on “Finish” to validate and save the parameter
block. You can view the configured parameter block by opening the data block
editor.

Multiple CPU Configurations

This appendix explains how to connect multiple TD 200s and S7-200 CPUs
together on one communication network. The TD 200s act as network masters and
do not interfere with one another. The CPUs can be either masters or slaves on
the network.

B.1 Configuring for Multiple CPU Communication

Figure B-1 shows a typical network. In this figure there are two TD 200s and two
CPUs. Each TD 200 communicates to one of the CPUs. The addresses of each
device are noted below the device in the figure. Refer to Section 3.8 for information
about how to set an address in the TD 200. Refer to the CPU’s programming
software documentation for help in changing the address of the S7-200 CPU.

In this example, the TD 200 Number 1 is configured to communicate to the CPU at
address 2 (CPU Number 1), and TD 200 Number 2 is configured to communicate
to the CPU at address 3 (CPU Number 2).

Note

Y ou can connect multiple TD 200s to a single CPU. You can store separate parameter
blocks for each TD 200 in different V memory locations in the CPU. See Sections D.1 and

3.8 for more information. If you do not store separate parameter blocks for each TD 200
that is connected to the CPU, any of these TD 200s can acknowledge the same messages
and use function keys to initiate operations in the CPU.

Warning

!

The CPUs provide 24 VDC on the communication connector to power devices such as the
TD 200.

Y ou must not connect the 24 VDC lines between CPUs. Doing so could result in damage
to the CPUs.

Y ou must only connect communication lines (pins 3, 5, and 8), not power lines (pins 2

Note

When you connect a PG 702 to a network of CPUs and TD 200s, the PG 702 does not
function if there are more than three TD 200s.

Note

The display update time slows as more TD 200s are added to the network.

TD 200 Parameters and Messages

Software Support for Configuring a TD 200

Some programming packages include a configuration utility for entering the
parameter block and messages for the TD 200. For example, version 1.2.1 of
STEP 7-Micro/DOS uses Utility 24 for configuring the TD 200. STEP 7-Micro/WIN
provides a “wizard” that makes it easy to configure the parameter block and the
messages in the data memory area of the S7-200 CPU (see Chapter 2). Refer to
your programming software and its documentation to determine whether it
supports a TD 200 configuration utility.

TD 200 Parameters and Messages

D.1 TD 200 Parameter Block

Understanding How Messages Are Displayed

The messages that the TD 200 displays are stored in the CPU. These messages
contain ASCII text, embedded values, and format information. The CPU enables
the messages through the use of a table of message-enable bits. There must be
one message bit allocated in V memory for each configured message. When the
program in the CPU says to display a message, the program sets that particular
message-enable bit. The TD 200 continuously polls the message-enable bits, and
if one of the bits is set, the TD 200 reads the corresponding message from the
CPU and writes the message to the display.

Understanding How the TD 200 Uses the Parameter Block

A TD 200 parameter block contains the TD 200 configuration information, and
must be created in the data memory (V memory) area of the S7-200 CPU in order
to establish an interface between the CPU and the TD 200. The TD 200 monitors
the CPU for either a parameter block identifier (ASCII characters “TD”) or an offset
to the parameter block.

If the TD 200 does not find the parameter block identifier (“TD”) in VW0, it uses the
value stored in VW0 as an offset to the TD 200 parameter block (see example in
Section 2.1). When the parameter block identifier is found, the next 8 or 10 bytes
provide the TD 200 with configuration information.

You can change the V memory address for the parameter block by means of a
setup menu. (See Section 3.8.) This allows you to connect two TD 200 units to one
CPU, with each TD 200 displaying different messages. Figure D-1 shows two
TD 200s connected to a single CPU. The parameter blocks for each of the TD 200
are stored in different V memory locations.

SIMA TIC TD 200 Operator Interface

C79000-G7076-C205-05

The default location of the parameter block is VW0, but you can store the
parameter block (or the offset to the parameter block) in any V memory location
between VW0 and VW999. (Use the Setup menu to change the location of the
parameter block. See Section 3.8.) If you change the location of the parameter
block, the TD 200 looks to that location for either the parameter block or the offset
to the parameter block.

If the parameter block identifier cannot be found, the error message
NO PARAMETER BLOCK is displayed. The TD 200 continues to monitor VW0 (or
the V memory location entered by means of the Setup menu) for either a valid
parameter block ID or an offset to a parameter block with a valid parameter block
ID.

Note

The TD 200 defaults to address 1 and attempts to communicate to a CPU at address 2.
See Section 3.8 to change the network addresses if other addresses are used.

Description of the Parameter Block Format

TD 200 Parameters and Messages

The parameter block consists of 10 or 12 bytes of memory which define the modes
of operation and point to the location in CPU memory where the actual messages
are stored, as shown in Figure D-2. When you power up the TD 200, it looks for a
parameter block identifier in the CPU at VW0, either the ASCII characters “TD” or
an offset to the parameter block location, and it reads the data contained in the
block.

TD 200 Parameters and Messages

D.2 Building the Parameter Block

Parameter Block ID Bytes 0 and 1

The TD 200 monitors the CPU for messages. To display the messages, it must first
locate the parameter block that contains the block ID information “TD”. The TD 200
parameter block is identified by two bytes; byte 0 must be the ASCII character “T”
and byte 1 must be the ASCII character “D”.

TD 200 Configuration Bytes 2 and 3

Byte 2 of the TD 200 parameter block allows you to configure the desired language
and the update time. Figure D-3 shows the information contained in Byte 2 of the
parameter block.

 (L) Language The language selection determines the display language of the

TD 200 menus.

 (U) Update Rate The update rate selection determines how often the TD 200

polls the S7-200 CPU for messages to display. The actual update time may be
slower depending on the size of the message and the processing required.

 (A) Alternate Character Set The character set selection enables the use of

an alternate character set designed for displaying bar charts on the TD 200.

TD 200 Parameters and Messages

Byte 3 of the TD 200 parameter block allows you to enable the Time-of-Day (TOD)
and Force menus, to select either 20- or 40-character display mode, and/or to
enable password protection (before allowing any editing). It also contains bits
which are set when either the UP or DOWN arrow keys are pressed.

 (C) TOD Clock and (F) Force The TOD Clock and Force selections allow you

to selectively enable the TOD Clock menu and/or the Force menu. Once either
is enabled, you are allowed to access that function in the TD 200. If the function
is not enabled, it does not appear in the TD 200 Menu mode.

 (D) Display Mode The display mode selection allows you to choose whether

display messages are one line (20 characters) or two lines (40 characters).

 (P) Edit Password The edit password selection allows you to enable a

four-digit password (using 0000-9999) to authorize an operator to edit variables
embedded in a message. The password itself is stored in bytes 10 and 11 of
the parameter block.

 (UA and DA) Up Arrow and Down Arrow The up/down arrow status bits

allow your program additional control of the TD 200 display. The TD 200 sets
these bits in the controller if you press these keys while the TD 200 is in display
mode, assuming there is no more than one message active. If your program
uses these bits, the program must reset these bits after they are used.

D-5

TD 200 Parameters and Messages

Prioritizing Messages

To ensure that you receive the most important message first, the TD 200 uses a
fixed priority scheme. In this scheme, a higher priority message displaces a lower
priority message. There is one message-enable bit for each message. Therefore,
you can have from 0 to 80 message-enable bits corresponding to the number of
messages. You must not use message-enable bits for any other purpose other
than enabling messages. The TD 200 requires that you allocate full bytes for
message-enable bits.

Messages are numbered in ascending order starting with message 1. Message 1
is located at the message address specified by configuration bytes 6 and 7 of the
TD 200 parameter block. Byte 0 of the message-enable bits is located at the
message-enable address specified by configuration bytes 8 and 9 of the TD 200
parameter block. The highest priority message is message 1 and the lowest priority
message is message 80. See Section D.5 for more information on message
priorities and the display of messages.

Figure D-5 shows the prioritization scheme and the correspondence between
message-enable bits and messages.

You must reserve eight bits of marker memory (M bits) for the TD 200 to use when
a function key is pressed. Your program can inspect these bits and take the
appropriate action when a key is pressed. One M bit is set by the TD 200 each
time the corresponding function key is pressed.

Note

The TD 200 does not automatically reset the function-key M bits after they are set. If you
use these bits within your program, you must then reset them from within your program.

TD 200 Parameters and Messages

Figure D-6 shows a referenced byte (MBn) and shows which bit of the byte is set
by each function key.

Warning

!

The TD 200 sets an M bit each time a function key is pressed. If you do not intend to use
function keys, and therefore do not assign an M byte address for function keys, the TD 200
defaults to byte M0 for the function keys. If your program uses bits in M0, and a user
presses any function key, the TD 200 sets the corresponding bit in M0, overwriting the
value assigned to that bit by your program.

Inadvertent changes to M bits could cause your program to behave unexpectedly .
Unpredictable controller operation could cause death or serious injury to personnel, and/or
damage to equipment.

Always reserve an M area address, even when your program does not utilize function
keys.

TD 200 Parameters and Messages

You must not use message-enable bits for any purpose other than enabling
messages. The TD 200 requires that you allocate full bytes for message-enable
bits.

Note

Y ou can set or clear the message-enable bits from within your program. The TD 200 may
also clear the message-enable bit following an acknowledge or an edit. See Section D.6
for more information.

Edit Password Byte 10 and 11 (Optional)

Bytes 10 and 11 of the TD 200 parameter block store a password that allows you
to edit the configuration of the TD 200 or to change variables. This password is a
four-digit integer (from 0000 to 9999). Byte 3 of the parameter block enables the
password protection. If you enable the password protection by setting the
password bit in byte 3, you must enter a password in bytes 10 and 11; however, if
you do not enable password protection in byte 3, you are not required to store a
password in bytes 10 and 11.

D.3 Formatting Messages

Messages can contain multiple text fields, format words, and variables. The
TD 200 allows two message sizes.

 20-character message mode - displays two messages at a time
 40-character message mode - displays one message at a time

Once you choose a message size, all messages must correspond to that size. The
size is selected on a system basis in the parameter block, and not on a
per-message basis. The TD 200 uses the setting of the message size to index the
messages stored in the S7-200 CPU V memory.

In applications where alarm or fault conditions can occur and notification is
essential, you can configure the TD 200 to display multiple messages.

This section shows you how to create a 20- or 40-character message.

Note

A message cannot have more than six variables. Additional variables are ignored and the
variable positions in the display remain blank.

TD 200 Parameters and Messages

Twenty-Character Message Format

The 20-character message format requires 20 bytes of V memory storage in the
S7-200 CPU for each message. Each message is displayed on one line of the
TD 200 display, allowing two messages to be shown at the same time. Figure D-7
shows an example of how a 20-character message can be formatted in the CPU
and displayed on the TD 200.

TD 200 Parameters and Messages

Forty-Character Message Format

The 40-character message format requires 40 bytes of V memory storage in the
S7-200 CPU for each message. Each message requires both lines of the TD 200
display, allowing only one message to be shown at a time. Figure D-8 shows an
example of how a 40-character message can be formatted in the CPU and
displayed on the TD 200.

TD 200 Parameters and Messages

D.4 Embedding Data Values in a Text Message

The TD 200 allows you to place data values within the message that you want to
display. You can display and edit these embedded values. Each embedded value
must be preceded by a format word which defines how the value is displayed and
whether the message requires acknowledgement.

Data Value Format Options

The format word in a message provides the following information:

 How the value is displayed-signed or unsigned; word, double word, or real

(floating-point); and decimal position

 Whether or not the message requires acknowledgement
 Whether the optional data value is editable
 Whether editing requires a password

You can use format words alone, with an optional word value, with an optional
double word value, or with an optional real (floating-point) value. The format word
uses two bytes of your message if it is not followed by a data value, four bytes of
your message if the format word is followed by a word value, and six bytes of your
message if the format word is followed by a double word value or a real
(floating-point) value. Figure D-9 shows each type of format word usage.

TD 200 Parameters and Messages

Defining the Data Value Format

Figure D-10 shows the bit values of Byte 0 and Byte 1 of the format word. Byte 0
uses only five bits (bits 0 through 4). Byte 1 uses only six bits (bits 0, 1, 2, and 4,
5, 6). All other bits of the byte (for both Byte 0 and Byte 1) must be set to zero.

Figure D-10Bit Values of the Format Word

Do not use non-printable characters in your message text: the TD 200 uses these
characters to identify the start of a format word. The non-printable characters are
ASCII codes 0 to 31 (0 to 1F hexadecimal).

Acknowledgement Bit 0

To ensure that important messages are displayed and acknowledged by an
operator, you can program a message to require acknowledgement. You do this by
setting the acknowledgement bit in the most significant byte of the format word.
Figure D-11 shows the placement of the acknowledgement bit in byte 0 of the
format word.

If you have more than one format word in a message because you have more than
one embedded value in the message, you only need to set the acknowledge bit in
the first format word of the message. The TD 200 ignores the acknowledge bit in
all subsequent format words of the message.

When a message requiring acknowledgement is enabled for display:

 The TD 200 displays the message and causes it to flash.
 The message is not removed or replaced on the TD 200 display, and continues

to flash, until the operator acknowledges it by pressing ENTER.

 The TD 200 sets the acknowledge-notification bit and removes the message

after the operator presses ENTER.

See Section D.5 for more information about how the TD 200 processes messages
with acknowledgement.

Acknowledge-Notification Bit 1

The S7-200 CPU program uses the acknowledge-notification bit to note that the
operator has seen and acknowledged a message. To acknowledge a message,

TD 200 Parameters and Messages

1. Move the cursor to the display line requiring acknowledgement and

2. Press ENTER.
After the operator presses ENTER, the TD 200 sets the acknowledge-notification

bit. The S7-200 program uses the acknowledge-notification bit to note that the
operator has acknowledged the message. You must design your S7-200 program
to reset this bit if you want subsequent notification. Figure D-12 shows the
acknowledge-notification bit, located in byte 0 of the format word.

TD 200 Parameters and Messages

You can design your S7-200 program to take other actions as a result of setting the
acknowledge-notification bit. Figure D-13 shows how you can use the
acknowledge-notification bit. For this example, VB21 is assumed to be the most
significant byte of the first format word of the message.

Figure D-13Sample Program for Using the Acknowledge-Notification Bit

Edit-Notification Bit 2

The TD 200 sets the edit-notification bit to 1 after an edit. The CPU can read this
edit-notification bit value to recognize when an editable data value has been
changed. The program can then read and make use of the edited value.

Note

The edit-notification bit does not reset automatically when subsequent edits are performed.
If you want the TD 200 to detect and notify you of a second edit operation, you must
design your program to reset the edit-notification bit to zero. Figure D-14 shows the
placement of the edit-notification bit, located in byte 0 of the format word.

If an embedded value is set to allow editing, you must design your S7-200 program
to check the edit-notification bit. When the embedded value is modified by the
user, your program must read the value and take any necessary action with it.

TD 200 Parameters and Messages

Caution

!

The edited (new) value that the user enters in an embedded message can be overwritten
by the value that was displayed in the message before the edit.

This could cause you to lose the newly edited value.
If you allow an embedded value to be edited, you must design your program to check the

edit-notification bit and to move and/or save the edited (new) value each time there is an
edit.

If a value is set to allow editing, you can move the cursor to the embedded value
and increment or decrement the value by using the UP and DOWN arrows. The
SHIFT-UP/DOWN arrow keys allow you to move to specific characters within the
variable. The longer you press the arrow key, the faster the value changes.

After you have changed the embedded value to the desired value, you must press
ENTER. Pressing ENTER causes the TD 200 to send the edited value to the
S7-200 CPU and sets the edit-notification bit in the format word preceding the
embedded value.

Figure D-15 shows an example of how you can use the edit-notification bit. For this
example, VB21 is assumed to be the most significant byte of the first format word
of the message, and the embedded value is a word-sized value immediately
following the format word (located in VW23).

Data Size/Format, and Decimal Bits 0, 1, 2 and 4, 5, 6

The least significant byte of the format word is used to specify the size, the format,
and the position of the decimal point in a displayed value. The selection of signed
or unsigned affects the editing range of a value. Unsigned values are restricted to
positive numbers. Signed values can be either positive or negative. Figure D-18
shows the placement of the data size/format and decimal point bits in byte 1 of the
format word.

 Unsigned words have a range from 0 to 32,767
 Signed words have a range from -32,768 to 32,767
 Unsigned double words have a range from 0 to 2,147,483,647
 Signed double words have a range from -2,147,483,648 to 2,147,483,647
 Real (floating-point) numbers have a range from "1.7549*10

"3.40282*1038.

TD 200 Parameters and Messages

The TD 200 displays all values as decimal numbers. Various types of data are
displayed in the following manner:

 Positive signed values are displayed without a sign.
 Negative signed values are displayed with a leading minus sign.
 Unsigned values are displayed without a sign.
 Values without non-zero digits to the left of the decimal point are displayed with

a leading zero on the left side of the decimal point.

 Real (floating point) numbers are displayed with the number of decimal places

that you specified (see Figure D-18). The value is rounded to the designated
level of precision. For example, if one decimal place were specified for the
value 12.567, the TD 200 would display “12.6”.

TD 200 Parameters and Messages

The number of display characters that are used to display a value varies. This
variation is not reflected in the number of bytes that are required to store the value
in the S7-200 CPU memory. In the CPU memory, two bytes are required to store a
word value, and four bytes are required to store a double word or a real (floating
point) value.

Table D-1 shows you how many display characters are required for each display
format and the maximum number of display characters required for each format.
For example, if you know that the size of the value will never exceed three digits
and will always be positive, then the number of display characters required will
always be less than the maximum values given in Table D-1.

For real (floating point) numbers, the TD 200 uses up to 20 digits to represent the
number. (This includes the number of decimal places that were specified in the
format word. See Figure D-18.) If a number cannot be displayed within the number
of digits available, the TD 200 displays “eeeeee” for that value.

TD 200 Parameters and Messages

D.5 Understanding Message Types

Every message falls into one of four possible message acknowledgement and
editing types. This section explains specifically how each message type is handled
by the TD 200. The four message types follow:

 No acknowledgement required. No edits allowed.
 Acknowledgement required. No edits allowed.
 No acknowledgement required. Edits allowed.
 Acknowledgement required. Edits allowed.

No Acknowledgement, No Edits Allowed

In this combination of no acknowledgement required and no edits allowed, the
TD 200 simply displays the message. The ENTER key has no function since there
are no editable variables within the message. The message can contain variables
that are updated at the update rate of the TD 200. This type of message is
replaced on the display if a higher priority message is enabled by the S7-200 CPU.
The operator can either press the UP or the DOWN arrow key to scroll through
other messages or press ESC to return to the Menu mode.

The TD 200 does not clear the corresponding message-enable bit in the S7-200
CPU.

Acknowledgement, No Edits Allowed

In this combination of acknowledgement required and no edits allowed, the TD 200
displays the message and makes the entire message flash (blink) until the operator
presses ENTER to acknowledge the message. Variable values are updated from
the S7-200 CPU at the normal update rate while the message is flashing.

When the operator presses ENTER, the TD 200:

 Sets the acknowledgement-notification bit in the first format byte of the

message.

 Clears the message-enable bit for this particular message. This causes the

message to be removed from the display on the next update cycle.

Another message cannot replace the one flashing until the operator acknowledges
the flashing message. This is also true even if a higher priority message is enabled
in the S7-200 CPU. If the TD 200 is configured for 20-character messages and the
CPU enables a higher priority message, the flashing message shifts to the second
line of the display. The operator cannot press the UP or the DOWN key to scroll
through other enabled messages until s/he acknowledges the current message.
