ANALOG GLOBALS
The WCC III system has 256 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 WCC III
system.
A WCC III 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
•
