Status Data Types (1788-CN2DN)

The table lists and describes module-defined data types for the 1788-CN2DN module. The data types are listed the way they are listed in the Controller Tags window from the
Logix Designer
Data Monitor. These tables include information for status as indicated by an "S".
The data type associated with the Status tag is sized according to the size you enter on the
Create/General Module
tab for Status Size. Each module-defined data type has minimum, maximum and intermediate sizes. The following tables specify how the sizes relate to the data type used for the tag.
