Column Title
Function
Legal Values
Node_Name
Name of Node to fetch data from
One of the Node
Names specified in
Section 5.2
Data_Type
This parameter determines how data is stored. Digital data is stored as
1’s or Zero’s. Non-Float types truncate the values, thus 0.6 is stored as
zero. ASCII stores the actual received ASCII characters
