Read
Specifies the type of data that triggers the display of a state.
Select
To
Single Bit
Trigger a 2-state indicator 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 states. Entries display in a sequence
corresponding to bits set at word address(es) starting with the
read tag address. The read tag data type is unsigned integer.
Value
Trigger a state based on a value at the read tag address.
Each state is linked to a different value.
Note: If using more than 16 states for the Least Significant Bit
(LSB) trigger, reserve up to 124 consecutive word addresses after the
tag address. Every 16 states = 1 word address, with up to 2,000
total states. The LSB will only use up to the word of the last state.
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.

Read Tag
Specifies the name of the tag address that triggers the display of a
state. If the tag does not exist, enter a tag name. Edit the tag

a state is triggered, the text associated with the state is printed on the
connected printer.
