6.5.4 ANALOG INPUT / INPUT CHANGE (OBJECTS 30/32)
In the following table, the Format column indicates that the associated data point format is determined by the entry in Table
6–2: Data Formats on page 6–34. For example, an “F1” format is described in that table as a (16-bit) unsigned value with-
out any decimal places. Therefore, the value read should be interpreted in this manner. Many of the values reported by the
489 have a size of 32-bits and have had their upper and lower 16-bit components assigned to separate points. Where indi-
cated, refer to the appropriate note following the table for more detail.
