STEP 1 Introduction to the TD 200 Wizard

The TD 200 Wizard guides you step by step through the configuration of your TD 200, assisting you in setting the parameters for the TD 200 features and entering ASCII messages. If you need specific TD 200 information to complete your configuration, refer to the SIMATIC TD 200 Operator Interface User Manual provided with your TD 200.

To use the TD 200 Wizard, follow these steps:

1.Select the menu command Tools > TD 200 Wizard… in order to open the Wizard.

2.Proceed to each new section of the TD 200 Wizard by clicking on the Next button.

3.When you have completed your configuration, click on the Finish button.

When the configuration is completed, it is appended to the data block with the information and addresses that you specify in the TD 200 Wizard. The information is stored in V memory, and each location is commented.

You can create multiple TD 200 configurations by invoking the TD 200 Wizard and specifying a new starting address for the new configuration.

If you want to make a change in a particular TD 200 configuration, invoke the wizard, choose the block with the correct starting address, and step through the TD 200 Wizard to the parameter you want to modify.

If you want to view the configured parameter block and messages after you are finished, you can examine them by opening the Data Block editor.

STEP 2 Language and Character Set

National Language: This setting affects the preconfigured menus and prompts in the TD 200. Select the language that you want the TD 200 to use for preconfigured menus and prompts.

Character Set: This setting determines what sorts of characters are available for you to use when you create user messages.

·Original TD 200, Bar Graph, Cyrillic, Latin 1 Bold, and Latin 1 are single-byte characters. You can display up to 20 single-byte characters per line of your message.
Note: Latin 1 Bold characters do not appear in bold face when you type them into the TD 200 Wizard or examine them from the Data Block editor of STEP 7-Micro/WIN 32. However, they appear correctly (that is, in bold face) on the TD 200 display unit.

·Simplified Chinese characters are double-byte characters. You can display up to 10 double-byte characters per line of your message.
Note: Some Latin 1 characters are available from the Simplified Chinese character set. Depending on your keyboard and/ or emulator, the Latin 1 characters may be available in single-byte format or they may be double-byte characters like the Simplified Chinese characters. If you use a mixture of single-byte and double-byte characters in a message, remember that the space next to a single-byte character can only be filled by another single-byte character or else an empty space.

The message editor displays 10 double-byte character places. You can fit any of the following combinations in a character place:

* one double-byte character
* two-single byte characters
* one single-byte character and one single-byte blank

You cannot fit one single-byte character plus one double-byte character in a character place.

Tip:

Do not accept the default character set (Latin 1) if your TD 200 release is prior than Version 2.0. Only use the Original TD 200 or Bar Graph character sets. If you choose a character set that is not supported by your version of the TD 200, the next time you power up your TD 200 with the new configuration you will receive a non-specific error message about your parameter block. To correct the error, change your character set selection and download the corrected configuration to the TD 200.

If you do not know the release level of your TD 200, power it off and then back on. The version number is displayed upon power-up.

STEP 3 Time of Day, Force, and Password

The Time-of-Day (TOD) and Force menu selections allow you to select whether the TOD Clock and Force menus are enabled. Once a selection is enabled, the user can access that menu in the TD 200. If a selection 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 Wizard for you to set the password. This password is not the CPU password. This password is stored in the TD 200 and only affects access to editing functions in the TD 200.

Tip:

Embedded data is configured on a later screen of the Wizard, but the password protection option which is offered here affects whether you can select "Should the 'user edit of data' be password-protected?" later.

STEP 4 Function Keys and Update Rate

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 PLC. To read TD 200 function keys, eight bits of memory (M bits) must be reserved for the TD 200. One M bit is set by the TD 200 each time the corresponding function key is pressed.

·Enter an M memory byte address number.

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 bot 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.


The update rate determines how often the TD 200 polls the PLC for messages to display.

·Select an update rate from the list box.

STEP 5 Message Size and Number of Messages

The TD 200 allows two message sizes. Select the desired size:

·20 character message mode – displays two messages at a time

·40 character message mode – displays one message at a time

The TD 200 allows you to configure up to 80 messages.

·Enter the number of messages you want to create.

STEP 6 Memory Address Assignments

The location where the 12 byte parameter definition is stored must be defined. It is normally located at VB0.

·Enter the starting byte address for a 12 byte parameter block.

·Enter the starting byte address for message enable flags.

·Enter the starting byte address for message information.

STEP 7 Enter Messages

Enter your message(s) into the 20 character field.

Note: The Original TD 200 and Bar Graph character sets require you to type special ALT key combinations for message characters. All other character sets can be typed using your ordinary keyboard and/ or emulator.

ALT Key Combinations for Original TD 200 Character Set

The TD 200 supports the display of certain international and special characters, which you enter in the TD 200 Wizard using ALT key combinations. To use an ALT key combination:

1.Ensure that the NUM LOCK for your keyboard is on.

2.Depress and hold the ALT key.

3.Using the number keypad on your keyboard, type in the 4-digit code for the character.

4.Release the ALT key.

Note that some characters that you enter in the TD 200 Wizard are represented differently in the Data Block Editor. However, they appear in your TD 200 just as you entered them in the TD 200 Wizard.

Embedded Data

a)Place your cursor in the correct position within the message, and click on the Embedded Data button.

b)Select data format and display format.

c)Enter the number of digits to be displayed to the right of the decimal point.
Caution: 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 space 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 in order to allow for the expected range of the data value.

d)Select whether the user must acknowledge the message.

e)Select whether the user is allowed to edit this data. (If you did not enable Password Protection during Step 3 of the Wizard, you can use the Back button to return to that screen and change your selection. Using the Back button does not cause you to lose any selections in the previous screens.)

f)If editing is allowed, select whether the 'user edit of data' should be password-protected.
