6. FUNCTIONAL
DESCRIPTION
The
Datalogger IDL 101 has altogether 32 logical variables for the collection, processing and output of various kinds of
sensor information. These 32 variables can be configured as:
Analog Input Variable
Analog Output Variable
Digital Input Variable
Digital Output Variable
Arithmetic
Variable
Setpoint
Variable
Alarm
Variable
For each variable various kinds of variable information and processing functions can be determined. The variable set-
ups are carried out by means of the
Configuration Software ICP100.
6.1. Analog Input Variable
The Analog Input Variable collects and processes the signals of the most common transducers. Currently a large
number of standardized and proprietary sensors are deposited in the Configuration Software ICP100 and will be copied
to the data logger during the configuration. The user can input further sensors. Only a few principles of measurement
form the basis of the acquisition of the varying quantities to be measured with these sensors. These are:
Measurement of voltage
Measurement of current
Measurement of resistance
Measurement of temperature with thermocouples and the ICJ104
For each one of these measurements the
Datalogger IDL 101 offers several types of measurement. For measurements
of voltage the types of measurement
single-ended and differential can be used. Current measurements have to be
carried out by measuring the fall of potential at an external shunt. Resistance measuring can be carried out in 2- and 4-
wire technique.
