Configuring the TD 200
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.
