HB_IDL101_E_V222.doc

Gantner Instruments Test & Measurement GmbH

1. GENERAL PRELIMINARY REMARKS

1.1. On This Manual

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

Datalogger IDL 101

please turn to the branch in charge of you or directly to one of

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:

Column 5

The pinout arrangements for analog and digital sensor variables are represented graphically, depending on the type of

measurement. The sensors must be connected to the Sensor Module according to these graphics.

Column 6

The PIN assignment is displayed for analog and digital sensor variables, determined by the Configuration Software ICP

100. The terminals are allocated with ascending variable numbers from AIn 1, DIn1, resp. I/O 1 upward.

Notice

: The PIN assignment can be influenced by the user only by the sequence of the configured sensors.

Column 7

The format in which data is to be transmitted via the bus is indicated as a format string with decimal point and unit.

For transmission and representation as ASCII-string the unit, field length and number of decimals are indicated. For

transmission in binary format, Boolean, Integer or Real is indicated in addition to these.

The measured values and the corresponding transmitted values can have different units. The conversion between the

measured values and the transmitted values can be defined for each sensor variable separately.

Column 8

Different range and error settings can be defined for each sensor, depending on the type of variable. Possible settings

for each variable and type of measurement are listed in the Short Description of the Configuration Software ICP 100.

Column 9

Various additional functions like filter settings, time base, logic formulas, threshold selection, etc. can be given for the

individual sensor variables, depending on their type. Possible additional functions for each variable and type of

measurement are listed in the Short Description of the Configuration Software ICP 100.

In the “

Module Settings

“ window the location, date and name of the user will be defined.

3. INSTALLATION

3.1. Mounting / Fixing

The

Datalogger IDL 101

has a snap-on mounting for installation on standard profile rails 35 mm (1.4 inch) according to

DIN EN 50022.

The four straps on the backside of the module will perform the mounting on the DIN rail. First you push the two straps

on the bottom behind the notch of the DIN rail and then you press the module on the DIN rail until the two straps on

the top snap in.

In order to take the module off the DIN rail slide the module sideward off the rail or in case it is not possible lift the

module slightly so that the straps on the top get off the notch and the module can be taken off easily by pulling it off

the DIN rail.

3.2. Protective System

The

Datalogger IDL 101

has an IP20 protective system. If required by the operating site, the modules are to be

installed e.g. in a splash-proof or presswater-resistant shell, as known from electrical installation engineering.

3.3. Ambient Temperature

The permissible ambient temperature for the

Datalogger IDL 101

in operation ranges from -30°C to +60°C. The

permitted storage temperature is between -40°C and +85°C.

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.
