It’s a common practice in some parts of the Allen-Bradley world to make heavy use of alias tags, especially when working on a Logix program that started as an automated conversion from PLC-5 or SLC-500. They are like crack for old-school programmers, and just as deleterious as crack if one targets them when polling. If you want requests to be consistently smaller than responses, use Logix structures and arrays, nested as needed, to pack all scada-relevant data into a few top-level tags, aiming for 400 bytes or more per named tag. Keep tag names and especially structure element names short.
