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
that a user may only access them after entering the correct 4Ćdigit password.

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?

Selecting Message Size and Number of Messages

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.

2-14

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
being allowed to edit the data value. You selected the password at the beginning of
the configuration process (see Figure 2-3); it is shown in the Password for Edit
field.
