The manual for the appliance on hand contains all important information concerning the function, installation and
initiation of the Intelligent Datalogger IDL101.
Descriptions of the Configuration Software ICP100 are available as a short description on CD with the PC-software.
1.2. Important Notice
Make sure to use the
Datalogger IDL 101
exclusively in accordance with the notices, technical data and operating
conditions mentioned in this manual. In case of inexpert handling or wrong application possible disturbances, measuring
errors, effects on or from other appliances and facilities as well as possible endangering of human lives or tangible
assets cannot be excluded!
Therefore if you have not yet worked with the
Datalogger IDL 101
, you should first of all study the manual on hand
thoroughly. While initiating or operating the appliance or in case service is required always observe the notices given in
this manual.
Please note further that there are other special regulations to be observed in case of application in potentially explosive
surroundings (EExe, EExi, ...). These are not, however, the subject of this manual, which only explains the general use
of the
Datalogger IDL 101
.
1.3. Contact for Inquiries
In case of inquiries concerning the

SYSTEM DESCRIPTION

Gantner Instruments Test & Measurement GmbH
2. SYSTEM DESCRIPTION
2.1. System Overview
The
Datalogger IDL 101
is part of a complete system for the distributed recording and processing of sensor signals
and digital status information. The general term for this system of
Intelligent Sensor Modules
is
"ISM".
Several system variants of the
Intelligent Sensor Modules ISM
are available for the various applications. Basically these
variants are distinguished by the number of their digital and analog inputs and outputs, by the number of configurable
sensor variables, by their display options and operating variants and by the number of arithmetic functions. Thus there
are two series of devices at the moment:
The modules of the series
"100",
where the
ISM 111
,
ISM 112, IDL 100
and
IDL 101
belong to, are free configurable,
multi-variable sensor modules.
2.2. Range of Application
The most varying measurement tasks can easily be solved by means of the different analog inputs and in combination
with the force output, which provides the local power supply for the transducers. Some typical applications are e.g.
measurement of temperature via resistance pyrometers or thermo couples, pressure measuring by means of wire
strain gauges, or position measuring and weight measurement by displacement transducers and force transducers.
With these applications the
Datalogger IDL 101
supports measuring methods with 2- and 4-wire technique. With
measurements of temperature via thermocouples you can also work with an internal cold junction compensation
(referred to terminals) in addition to the external cold junction compensation. The preparation of signals required in
accordance with the sensors used, such as amplification, linearization, offset correction etc. can be adjusted
individually per software. An external amplifier is not required.
The 16 digital signal in-/outputs can be individually configured as inputs and/or outputs.
The digital signal inputs can be used, among other things, to connect switches, approximation initiators, digit emitters
and oscillators. Thus status indications can be collected and tasks like e.g. position measuring, displacement
measurements, angular measurements, frequency measurements and timings can be carried out.
Status signals and alarm messages can be output at the digital in-/outputs if they are configured as outputs. These
signals can be used to control indication devices like lamps or sound generators or they can be used for further
processing.
All data can be transmitted via the integrated RS485 communication interface to an overriding control (PLC) or to a
computer (PC). Up to 127 modules can be connected with the two-wire line over distances of several 100 m (328 ft).
At the same time the communication interface serves the purpose of centrally programming and configuring the
Datalogger IDL 101
for the concrete application via bus from a PC.
With an RS 232 interface either a point to point connection over 20 m is possible only but on the other hand all
functions of the RS-485 interface are available.
A corresponding
Configuration Software ICP 100
, executable on usual commercial PCs under Windows™, is part of the
ISM
-system.

2.4. Configuration Software ICP 100
The 32-bit
Configuration Software
ICP 100
for Windows
®
serves to configure and adjust the sensor modules of the
“100“
series (e.g.
ISM 111
,
ISM 112
,
Datalogger IDL 100 and IDL 101
) individually to their desired application. The
channels can be defined in the Variable Settings Table by simple mouse clicks. Additional sensors can be created at
any time and inserted to the database. The signals will be linearized, scaled and formatted automatically. With the
new function editor sensor signals can be connected with mathematical and logical functions. Also the adjustment of
PID controllers is much easier now.
At start up of the
Configuration Software ICP 100
the bus will automatically be searched for modules. Independent on
the protocol and baud rate all found devices will be listed. A new feature is the possibility to configure several modules
simultaneously. This offers an easy way to copy a configuration from one device to another.
At the following pages a configuration example of an
ISM 111
is shown by a screen picture of the “Variable Settings
Table“ with descriptions of the different columns.
The entire configuration of a module can be made in a window of the Configuration Software:

The terminal designations A and B are exchanged, compared with the PROFIBUS-definitions, for all devices of the ISM series
“100“
and
the
Datalogger IDL 101. This means that in multi-vendor-systems the bus lines A and B must be exchanged when they are connected to a device of the
ISM-line or a Datalogger IDL 101.

3.5. Connection Technique
connection technique: plug-in terminal screws
nominal cross section: 1.5 mm² (0.002 square inch)
unifilar/fine-strand (AWG 16)
length on which the wire has to be stripped : 6 mm (0.2 inch)
The wires are connected with the module by means of terminals. The terminal screws are integrated captively into the
terminal strips. All terminal strips are pluggable and can be detached from the module.
The best way to take the pluggable terminal strips off the module will be performed by assistance of a small screwdriver
placed as a lever between terminal strip and module front.
No more than 2 leads should be connected with one clamp. In this case the leads should have the same conductor
cross section.
For the binding of stranded wire we recommend the use of wire end ferrules.
Notice:
The connection of the wiring respectively the plug out and plug in of the terminal strip is only allowed in a
power off status.
Notice:
In order to prevent disturbing influences on the sensor signals and the module shielded wires have to be used
for the power supply, the bus connection and the signal lines.
3.6. Power Supply
Voltage Range
+10 ... +30 VDC
Power Input
max. 1 W
Protection
excess current (0.1A slow
. blowing fuse)
excess voltage
polarity conversion
Figure 3.2 Connection of the distribution voltage
Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the
Datalogger IDL 101
. The
input is protected against excess voltage and current and against polarity conversion. The power consumption remains
approximately constant over the total voltage range, due to the integrated switching regulator.
