Column 1
The type of variable is indicated by a short designation. Up to 32 variables can be input and parameterized for the
Datalogger IDL 101. The short designations and corresponding channels are:
•
AI : Analog Input Channel
•
AO : Analog Output Channel
•
DI : Digital Input Channel
•
DO : Digital Output Channel
•
AR : Arithmetic Channel
•
SP : Setpoint Channel
•
AL : Alarm Channel
•
CO : Controller Channel
Column
2
A variable indication with max. 20 characters can be given for each sensor variable.
Column
3
The type of sensor connected appears for any Analog Sensor Variables. The sensor can be selected from a database,
which can be expanded by further user-defined sensors. This field remains empty for variables with no sensors
connected.
Column 4
