The 7th line describes the fourth measurement value "Info" in the measurement data container used:
Info:
"Info" should be used as the name for the measurement value.
astr.50:
The data type used for the measurement value should be an ANSI string.
After the dot the number of characters (50 in the current example) are specified.
title:
Name of the measurement value that is displayed on the server
index:
Is used for the user-defined sorting of the fields in the selection lists.
index is not specified for "Pump", thus "Pump" automatically receives index 2. The sorting order of the
channels is therefore "Height", "Delay", "Pump", "Info".
14.3 Special values of the data types
Each numerical data type supports special states, such as NAN (Not a Number). If such a value is detected
on the server, the standard display and further processing in myDatanet is applied.
