When you define a point, the following fields have values that are unique to or have special meanings for the Allen-Bradley Communications enabler.
General Tab
On the General tab in the Point Properties dialog box, you may configure points for Read or Read/Write access.
When you are reading / writing data between CIMPLICITY software and a Floating Point file (F), define CIMPLICITY points using the REAL data structure type.
When you are configuring array points, make sure that the size of the array is within the limits of the file. CIMPLICITY software does not declare an array configured beyond the end of a file as invalid.
Device Tab
On the Device tab in the Point Properties dialog box.
