MicroLogix Data Formats
The data selected for a controller address must reflect the same format
as the data actually stored in that address. This is the only way you
can ensure that correct, consistent information is displayed.
For example, selecting 16 Bit Signed Integer format for address N7:10
displays data one way and selecting 16 Bit BCD format for the same
address displays data another way. It is important to understand each
data format and its characteristics.
The following table illustrates all data formats supported by
MicroLogix controllers including the point types and ranges applicable
to each format, and whether the scaling may be used.
Bit Format
The controller stores a binary (0 or 1) status at each bit address. The
MicroView reads a bit address and determines whether the
operational status of the bit is ON (1) or OFF (0).
You can specify associated text to be displayed for either state of a
specified bit. This description can be up to twenty characters.
