2 SYSTEM DESCRIPTION
2.1 System Overview
The COMBILOG 1022 is a data logger with compact
design, combined with integrated LC-display and memory slot
suitable for SD cards.
This data logger was developed for meteorological, hydrological and environmental measuring systems, but it is equally suitable for countless further applications in industrial production.
The COMBILOG 1022 features high performance, compact
design (SMD components), low power consumption and moderate price.
The data logger is equipped with 8 analogue and 6 digital
measuring channels; further channels for numeric calculation
may be configured. Four serial interfaces RS232, RS485, USB
and Ethernet are built-in, featuring communication via ASCII,
PROFIBUS or MODBUS. Data storage is achieved by internal
Flash or SD memory card, optionally.
„SELECT“ switch and 4-line LCD on the front panel allow to
enter or modify a number of different modes and functions,
such as scan rate and averaging time, as well as offset or gain.
The COMBILOG 1022 can easily be mounted on a 35 mm
standard rail using its „snap-in“ clamp and is therefore suitable
for control cabinet installation or similar.
Thanks to its low power consumption, battery supplied systems
are possible, whereby the use of a solar panel enables any extension of measuring period.
Hardware Manual COMBILOG 1022
12
For applications like outdoor use there is a version with stainless steel housing available, as well as various other accessories.
Configuring of the data logger is accomplished by means of an
easy to handle WINDOWSTM 98 / ME / NT / 2000 / XP software.
2.2 Range of Application
As described under (2.1), the most varying measurement tasks
can easily be accomplished by means of the COMBILOG 1022.
Some typical applications are e.g. measurement of temperature via resistance thermometers (Pt100), operation with combined sensors with current- or voltage output (e.g. wind speed
measurement with DC generator) or position measurement and
weight measurement by displacement transducers and force
transducers. With these applications the data logger
COMBILOG 1022 supports measuring methods with 2-, 3- and
4-wire technique. The signal processing required in accordance
with the sensors used, such as gain, linearisation, offset correction etc. can be adjusted individually by software. An external amplifier is not required.
The digital signal inputs can be used, for example, to connect
switches, initiators, digit emitters and oscillators. Thus status
indications can be collected and tasks like e.g. position measurements, displacement measurements, angular measurements, frequency measurements and timings can be carried
out. Furthermore special 8-bit-Graycode-transmitters can be
connected.
Special calculations of measured values are possible by arithmetic channels. In case the 8 analogue and 6 digital inputs are
not sufficient, other modules can be connected to the data
Hardware Manual COMBILOG 1022
13
logger via the RS485 bus. In this case the COMBILOG is used
as a bus master to read the measured values from the slave
modules.
All data can be transmitted via the integrated RS485 communication interface to a subsequent control (PLC) or to a computer (PC). Up to 127 modules can be connected with the twowire line over distances of several km. At the same time the
communication interface features programming and configuring
the individual application from a PC.
If the data logger COMBILOG 1022 is not integrated in a bus,
an additional RS232-interface is available for the user. This interface allows only a point-to-point connection up to max. 20 m
(65 feet), but all functions of the RS485-interface remain available.
Furthermore the data logger can send messages in case of
user definable conditions automatically via modem or SMS.
A configuration program is included (requires Microsoft
WINDOWS 98,ME,NT,2000, XP).

3 INSTALLATION
3.1 Mounting / Fixing
The data logger COMBILOG 1022 has a snap-on mounting for
installation on standard profile rails 35 mm (1.4 inch) according
to DIN EN 50022.
Installation on the DIN rail is performed by means of the four
straps on the rear side of the data logger. First push the two
straps on the bottom behind the notch of the DIN rail and then
press the data logger on the DIN rail until the two straps on the
top snap in.
In order to take the data logger off the DIN rail slide the module
lateral off the rail or in case it is not possible lift the data logger
slightly so that the straps on the top get off the notch and the
data logger can be taken off easily by pulling.
Attention: Refer to protection earth hints in chapter 3.5!
3.2 Protective System
The data logger has an IP20 protective system. For outdoor installations data logger COMBILOG 1022 can be installed in a
stainless housing type 9920, thus featuring IP66 standard.
Hardware Manual COMBILOG 1022

3.5 Connection
Connection: plug-in screw terminals
Nominal cross section: 1.5 mm² (0.02 square inch)
unifilar/fine-strand (AWG 16)
Length of wire stripping : 6 mm (0.2 inch)
Alternatively available: LP-terminals (spring loaded)
(upon request)
Protection earth: 6.3mm series tabs at rear
side of housing
The best way to pull off the screw terminals is to use a small
screwdriver, placed as a lever between terminal and the front
of the data logger.
Not more than 2 leads should be connected with one clamp. In
this case the leads should have the same conductor cross section.
Note: Wire connection is only allowed during power off.
Note: In order to avoid influences from noise on the sensor sig-
nals shielded wires should be used for the power supply, the
bus connection and the signal lines.
ATTENTION: Before final installation, a suitable protection
earth cable with terminal has to be connected to the ground
connector at the back of the data logger. Assure that the connection has a low impedance after mounting.

Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the data logger COMBILOG 1022.
The input is protected against excess voltage and current and
against reverse polarity. The power consumption remains approximately constant over the total voltage range, due to the integrated switching controller.
Due to its low current consumption (max. 110 mA at 12 VDC)
the data logger can also be remote-fed via longer lines. Several
data loggers can be supplied parallel within the admissible
voltage range, considering the voltage drop in the lines. The
supply lines can also be installed in one common cable, together with the bus line, if required.
In order not to charge the data logger’s supply voltage unnecessarily, a separate power supply for sensors with a large current requirement is recommended.
Hardware Manual COMBILOG 1022
24
3.7 Bus Connection
In general the data logger is connected to the bus by applying
the signal leads A and B of the incoming bus cable and A' and
B' of the outgoing bus cable together to one terminal on the
module (figure 3.3).
Alternatively the bus can also be connected by a "stub cable"
as shown in figure 3.4.
Owing to the removable terminal, the bus connection to other
data loggers remains valid, even if one data logger is replaced
by another.
Figure 3.3 Connection of the data logger to the bus
Note: When connecting the logger to the bus, the two bus interfaces A and B must not be interchanged.
Note: The stub cable should be as short as possible, not
longer than 30 cm (12 inch).
Hardware Manual COMBILOG 1022
25
Figure 3.4 Connection of the data logger to the bus by a stub cable
3.8 Sensor Connection
The analogue and digital signal inputs and outputs are wired
according to measurement task, to the transducer (sensor) that
is used, and to the number of connected sensors. The pinout
arrangements for the various types of measurement are described in chapter 5. The respectively valid pin assignment is
determined by means of the configuration software.
Since the digital outputs are "passive" the processing of external elements always requires an external current supply. In case
of larger loads this should be independent of the data logger
supply.
At the connection of inductive loads a connection with a diode
is required in order to prevent possible damages by induced
voltage.
Hardware Manual COMBILOG 1022
26
Following devices can be connected directly to the digital outputs: signal lamps, small relays, switching relays for larger
loads, acoustic signal installations, buzzer respectively beeper
etc., as long as the connected loads are not exceeding the values described in the technical data chapter 12.
3.9 Several Sensors at one Data Logger
The data logger COMBILOG 1022 can simultaneously receive
and process sensor signals from several different sensors. As
many sensors can be connected as there are analogue and digital signal inputs and outputs available (14 sensors max.;
8 analogue and 6 digital sensors).
3.10 Module Jack
The data logger COMBILOG 1022 has a bus connection facility
on the left and on the right side of the housing, featuring interconnection of the +10…30 VDC supply and the bus signal, for
several COMBILOG.
This kind of bus connection and of power supply is particularly
advantageous if several data loggers are mounted on one common profile rail side by side. In this case the connection via the
terminals can be dropped, except for one module.
Note: If some COMBILOG 1022 are connected using the mod-
ule jacks, the supply power has to be provided using the screw
terminals. The power supply via the module jacks has to be
used only for expansion modules.
Hardware Manual COMBILOG 1022
27
Note: It is necessary to take care that the current at the Module
Jack is not higher than permitted. Thus, the power supply
preferably should be led to the centre of the module line. For
the same reason a 100 mA self resettable fuse protects the
module connector of the COMBILOG 1022 against short circuits.
The permanent current drawn from the module connector shall
not be higher than 100 mA.
Hardware Manual COMBILOG 1022
28
4 SIGNAL PROCESSING
The data logger COMBILOG 1022 has eight analogue inputs
and six digital inputs/outputs. Several different sensor signals
as well as digital inputs and digital output signals can be connected and processed simultaneously.
4.1 Analogue Inputs
The analogue inputs serve to collect sensor signals, or to acquire control values respectively. They are particularly designed to measure voltages, currents and resistances.
There are 8 equal analogue inputs, each input can be configured individually.
Note: Overloads of more than ± 10 VDC will lead to false
measuring results in the according analogue input channel.
Overloads of more than ± 15 VDC will also have influence on
the measuring accuracy of the other input channels!
4.2 Digital Inputs/Outputs
The six digital inputs/outputs of the data logger can be configured - independent of each other - as inputs or as outputs.
The current status (in/out) is signalized by one LED each.
Hardware Manual COMBILOG 1022
29
As inputs the I/Os can be used for collecting feed-back signals,
for measuring frequencies, as counters or for receiving special
serial 8-bit-Graycode signals. Status information can be issued
by the outputs. Thereby host-controlled or process-controlled
status outputs are possible.
The digital inputs have an excess voltage protection (transil diodes), with nominal threshold 30 V. Input voltages between
2.0 VDC and 30 DC are interpreted as logic LOW ("0"), input
voltages lower than 0.9 V as logic HIGH ("1"). The maximum
input current is 1.5 mA.
Figure 4.1 Definition of signal levels and logic levels
The outputs are open-collector type with a maximum voltage of
30 VDC and a maximum current of 100 mA.
4.3 Power Switch
The data logger Combilog 1022 has two power switches which
act as voltage supplies for external sensors.
A power switch can be assigned to an analogue channel and
configured with a lead time (see chapter Power Switch ).
The supply is switch on with a configurable time before the selected analogue input channel will be measured.
