ANALOG GLOBALS
The ECC/WCC II system has 128 analog globals. The term
“ analog” means a numerical value represented by a directly
measurable quantity such as temperature, pressure, etc. The
term “ global” means information which is shared by all of the
satellite controllers in the system. Therefore, an “analog global”
is a numerical value which can be used by any satellite controller
within the ECC/WCC II system.
An ECC/WCC II system has the capability of generating the value
of the analog globals by the following methods:
Averaging several numerical values
Sorting several numerical values to fi nd the highest
number, lowest number, or any number in between
Calculating a “sliding window” average
Averaging one value over a period of time
Add data readings together to obtain an
accumulated total
