Creating tags

4–17
For tags with Device as the data source, select the data type that
matches the format of the data stored in the programmable
controller or Windows
® application. If you are using direct driver
nodes, use the Default data type to automatically match the data
format specified by the address.
If you are using OPC or DDE nodes, do not use the Default data
type because the default might not be as expected.
For tags with Memory as the data source, select the data type that
matches the format of the data you will store in the tag. Choosing
Default is the same as choosing Floating Point.
Configuring a digital tag
1. If the tag is part of a folder, select the folder in the folder hierarchy.
The folder name appears in the Name field and is the first part of
the tag name.
2. Type a tag name. If the tag is part of a folder, type the name after
the backslash (\).
3. For Type, select Digital.
Data type Description Range
4–Digit BCD 4–digit binary–coded
decimal 0 to 9,999
For a tag with a Long Integer data type, if the minimum,
maximum, scale, offset, or initial value is used with a decimal
point, RSView32 stores the value in floating point format. This
means that the maximum value for the tag is 16,777,216, which
is the maximum integer value for single–precision floating point
numbers. IMPORTANT
