Creating Message Displays

Publication 2711-6.0

Read

Specifies the type of data that triggers a message to display.

Select

To

Single Bit

Trigger a 2-message display by setting or clearing a bit at the
read tag address. The number of states must be set to 2
before the single bit option is available.

Least Significant Bit

Trigger multiple messages. Messages display in a sequence
corresponding to bits set at word address(es) starting with the
read tag address.

The tag data type for least significant bit is unsigned integer.

Value

Trigger a message based on a value at the read tag address.
Each message is linked to a different value.

Note: If using more than 16 messages for the Least Significant Bit
(LSB) trigger, reserve up to 124 consecutive word addresses after the
tag address. Every 16 messages=1 word address (maximum of 2,000
messages). The LSB only uses up to the word of the last message.

For the Value option, you must select the format of the data from the
Data Format list box. The data type of the read tag must be
compatible with the selected format for the application to validate.
