5.4.2 Defining Input, Memory, and Output tags
Input, Memory, and Output tags are all basically the same type of data structure.
Individual tags differ from each other in only two ways:
How the tag is used – Input and Output tags are typically associated
with the various
I/O points on the Pointe Controller unit. Memory tags are
used as “scratch values within the program itself and typically do not have
any direct readout.
What size the tag is – Every tag must be defined as a specific register
size and numeric mode. The size/mode of the tag determines the range of
values the tag can have:
SIZE/MODE VALUE RANGE
Bit/Boolean 0 or 1
8-bit Unsigned 0 to 255
16-bit Unsigned 0 to 65,535
32-bit Unsigned 0 to 4,294,967,295
8-bit Signed -128 to 127
16-bit Signed -32,768 to 32,767
32-bit Signed -2,147,483,648 to 2,147,483,647
32-bit Real -3.4 x 10^38 to 3.4 x 10^38
