2 Safety instructions
This operating manual is part of the device. It must be kept in the vicinity of the controller as well as for future
use so that it can be consulted when required. The operating manual must be available to the operating and
maintenance personnel at all times in order to avoid operating errors. The safety regulations, instructions and
information must be strictly observed and complied with. During repairs on the entire E*LDS system, the
accident prevention regulations and general safety regulations must be strictly complied with. Important
information (safety instructions and hazard warnings) are indicated by appropriate symbols, see chapter
Conventions. Follow these instructions in order to prevent accidents and danger to life and limb, as well as
damage to the E*LDS system!
Always observe the following information:
Workontheelectricalsystemmayonlybeperformedbyauthorised, skilled personnel (accordingtothe
definition of skilled persons in DIN/VDE 0105 and IEC364) while observing the applicable
- VDE regulations
-Localsafetyregulations
-Intended Use
-FivesafetyrulesaccordingtoDGUVRegulation3
-ESDmeasures
-Operatingmanuals
For safety reasons, the equipment must not be used for any applications other than described in the
operating manual and only for the intended use.
Before using the device, check whether it is suitable for your application with regard to its limit values.
The equipment must be installed in an electrically shielded area within the switch cabinet.
Before connecting the device, it must be checked whether the power supply is suitable for the device.
Coded connectors must be used, as there is a possibility of plugging in non-coded connectors in such a
way that there is a danger to life and limb!
Specified ambient conditions (e.g. humidity and temperature limits, see chapter Technical Data) must be
observed and complied with at all times to prevent malfunction.
Before switching on the device, check the correct wiring of the connections.
The device must never be operated without its housing. If the intended use requires opening the housing,
the control unit must be disconnected from the power supply before opening the housing.
Note the maximum load of the relay contacts, see chapter Technical Data.
Note that all supply lines from and to the device, particularly those of the CAN bus and Modbus, must be
shielded or installed sufficiently far away from live cables. This prevents faulty measurements and protects
the device against electrical interference via the analogue inputs. Connection in parallel of RC elements is
recommended for applications with critical environment.
Contact the supplier in the case of any malfunction.
DANGER

2.1 Disclaimer in the event of non-compliance
These operating instructions contain information on the commissioning, function, operation and maintenance
ofthecontrolsandoftheassociatedcomponents.
2.2 Requirements for the personnel
Special technical knowledge is required for planning, programming, installation, putting into service and
maintenance work. This work may only be performed by skilled, specially trained personnel. The installation,
putting into service and maintenance personnel must have training that authorises them to perform
interventions in the system and the automation system. The planning and programming personnel must be
familiar with the safety concepts of automation technology. Working on electrical systems requires special
technical knowledge. Work on electrical systems may only be performed by instructed electrically skilled
persons or under the guidance or supervision of such persons. The applicable regulations (e.g. DIN EN 60204,
EN 50178, DGUV Regulation 3, DIN-VDE 0100/0113) must be observed. The operating personnel must be
instructed in how to handle the system / machine and the controller and must be familiar with the operating
instructions.
ATTENTION
Warning of damage to goods!
In our experience, the transmission of fault messages is not yet functional during the putting into
service (no internet connection, no telephone line installed, etc.). It is strongly recommended in such
cases to monitor the controller via the CAN bus using a system centre, a store computer or an operator
terminal and to enable the transmission of fault messages, for example using a GSM modem via a
mobile telephone system. In standalone operation, or as an alternative to monitoring via system
centre / store computer / operator terminal, an available alarm contact on the controller must be used
to enable the transmission of fault messages via a telephone network.
For more information, refer to E*LDS basics, safety instructions, CAN bus & Modbus.

Observance of these operating instructions is a prerequisite for safe and trouble-free operation.

2.5 Electrostatic-sensitive components and control components (ESD)
All electrostatic-sensitive components and control components (referred to as "ESD" below) are labelled with
the warning sign shown. Electrostatic charges arise from friction of insulating materials (e.g. floor covering,
items of clothing made of synthetic fibres etc.). Even small charges can result in damage to or destruction of
components. Such damage is not always immediately noticeable; in some cases, it does not lead to failure until
after a certain operating time.
2.6 EGB - Richtlinien zur Handhabung
Transport and store ESDs only in the protective packaging provided.
Avoid materials that may produce electrostatic discharge, for example
Plastic containers and table tops
Synthetic fibre clothing
Plastic-soled shoes

Compared to the GLT 3010, the GLT 5010 can embed the GLT channel configuration "glt.cfg" (data point
description) in the user application running on it. Compared to the GLT 3010, there is no longer a separate
"glt.cfg" file that has to be manually imported into the system centre. In addition, the Virtus 5 can then manage
more data points per GLT 5010.
The current procedure for importing the GLT-3010 configuration is to import it into the system centre via
LDSWin. This currently results in the following disadvantages:
The GLT configuration "glt.cfg" contains all data points about all GLT 3010 controllers that are in the system.
The GLT 3010 controllers can also be located in different maintenance groups, e.g. in the "building
management system" group and in the "refrigeration" group for heat recovery. In the case of any change, it
must be ensured that the corresponding Signal Lists for all maintenance groups have been merged before
importing.
In the case of any change in the CODESYS project of the GLT 3010 and the possibly resulting changes in
the data points, it must currently be ensured that the corresponding GLT configuration is also available in
the system centre or is imported subsequently. If this is not the case, then incorrect or implausible actual
and setpoint values are displayed in LDSWin because the GLT configuration does not match the CODESYS
project of the GLT 3010.
The new concept envisages that the GLT channel configuration is embedded in the CODESYS project of the
controller.

these aspects, see chapter Compatibility. The hardware of the GLT 3010 controller is not affected, i.e. a GLT
3010 controller can be transformed into a GLT 5010 controller via a firmware upgrade. The following are
created from the EXCEL Signal List with the GLT channels for a DDC using the Signal List Tool
the files of the PLC code for the CODESYS project and
file of the GLT channel configuration (glt.cfg)
The GLT channel configuration is then integrated into the CODESYS project and is stored in the controller after
import. The GLT channel configuration is then transmitted via CAN bus to the system centre and is stored there.
When a connection is established, LDSWin retrieves all available GLT configurations and displays them in the
usualway.

3.2.1 Number of data points
A maximum of 4 controllers of the type GLT x010 can be used system-wide in the E*LDS system.
GLT 3010:
The system centre can manage a total of 600 data points system-wide (150 per controller) and archive a
maximum of 255 data points.
GLT 5010:
The system centre can manage a total of 2000 data points system-wide (500 per controller) and archive a
maximum of 1020 data points (255 per controller).
3.2.2 Synchronisation
In this chapter, the aspects of synchronisation of the GLT channel configurations of the GLT 5010 and the
system centre will be covered.
Synchronisation from the perspective of the system centre
In the case of a first start or a restart of the system centre, the system centre will query the GLT channel
configuration of all existing GLT 5010 controllers in the field and persist if necessary.
Synchronisation from the perspective of the GLT 5010
In the case of a restart of the GLT 5010 or a change in the GLT channel configuration in the GLT 5010, the GLT
5010 sends its GLT channel configuration to the system centre automatically.
3.2.3 Compatibility
The new functionality is already integrated in the Virtus 5 series and GLT 5010. A suitable LDSWin version that
supports the necessary functionalities is required for this. A system centre in the CI 4000 series can be
converted into an equivalent system centre in the CI 5000 series by purchasing an upgrade.
New installation
Due to the larger data volumes, the Virtus 5 series will no longer support the CAN BUS PC adapter
("Netporty") in the future.

In the case of new installations with a system centre in the CI 5000 series, GLT 5010 controllers must
be used in order to be able to use the concept with the separate GLT configurations.

Existing installations
In the case of existing installations with an installed system centre CI 4x00, it is not possible to use GLT 5010
controllers. The separation of GLT configurations is not supported in the CI 4000 series and GLT 3010. Also, in
the case of replacement of a defective GLT 3010 controller, it must be replaced by a GLT 3010 controller again.
Backward compatibility
The two concepts are mutually interlocked in the system centre of the CI 5000 series; mixed operation is not
possible. The support of the concept of separate GLT configurations is exclusively implemented in the system
centre of the CI 5000 series, i.e. depending on the connected components, either the old previous GLT concept
or the new GLT concept with separation of the GLT configurations is supported. The rules for interlocking are
defined as follows:
If an "old" GLT configuration is stored in the system centre, then the old, previous GLT concept is active.
If a GLT 5010 controller is active on the CAN bus and no "old" GLT configuration has been imported into the
system centre, then the new GLT concept is active.
If a GLT 5010 controller is active on the CAN bus and the component is managed as a participant in the
system centre, it is no longer possible to import the "old" GLT channel configuration into the system centre
via LDSWin.
Nevertheless, if mixed operation of the GLT 5010 controller and GLT 3010 controller takes place, then this is
escalated accordingly via system messages in the system centre; there is - for the components of the variant
that was added later - only "node guarding" (participant monitoring on the CAN bus) of the components.
The rules mentioned below should be understood analogously. If other parameters or indicators are
more suitable for detection, these can be selected after consultation.

4 Tasks of the GLT x010
The controller GLT x010 is a freely programmable DDC (Direct Digital Control) according to IEC 61131-3. IEC
61131-3 includes the following languages:
Abbreviation Description Note
STL Statement List Text: A sequence of mnemonics and operators like in assembler
LAD Ladder Logic Graphic: Resembles an electrical wiring diagram lying on its side
FBD Function Block Diagram Graphic: Reminiscent of logic plans
SFC Sequential Function Chart Graphic: Sequence chains comparable with Petri nets
ST Structured Text Text: A high level language with the syntax of PASCAL
The programming environment used is CODESYS from 3S1) which is supplied with standard libraries. These
contain ready-made modules such as PID controllers, timers, counters, triggers, flip-flops, mathematical
modules, etc. With CODESYS, almost object-oriented programming with declaration of types and the use of
individual types in any number of independent instances is possible.
CODESYS has yet another powerful language that complements IEC 61131-3:
Abbreviation Description Note
CFC Continuous Function Chart. Free
graphical function block diagram editor.
The graphical function blocks can be freely arranged in the editor as in
an RI Flowchart. Feedbacks are allowed.
1): Protected trademark, see bibliography.
For individual control applications, e.g. in the field of refrigeration and building automation, the following
functions can be realised with the controller in combination with Virtus 5 and LDSWin:
Control functions
Regulation functions
Fault reporting
Fault archiving
Monitoring functions
Archiving functions
These functions depend on the individual programming of the controller.
Applications (examples)
Monitoring of safety equipment
Controls and regulation of heating circuits with monitoring of pumps and valves
Weather management
Hot water preparation, especially via heat recovery
Individual heat pump control systems
Integration of third party controllers via Modbus RTU

5 Functions of the GLT x010 and set-up
5.1 Implementation
The freely programmable controller is shipped from the factory without application functions. There is no
application loaded. All relay outputs are switched off. In contrast, the inputs are constantly read in even when
the application is missing or stopped. The values can be visualised with LDSWin.
If the application is missing or stopped, the life lamp (life LED) on the lower circuit board lights intermittently
(periodically on for approx. 3 s and off for 0.3 s).
Only the firmware that has the following functions is installed at the factory:
1. Install firmware - with and without applications
A function that allows installing a new firmware via the serial interface RS232. There are two versions of the
software installed on delivery:
a. Firmware without application
b. Firmware with application
2. Provision of the interfaces for CODESYS
a. RS232 - only for the CODESYS programming system
b. RS485 - only for Modbus RTU
c. CAN bus - only for the E*LDS system
d. EEPROM - for the non-volatile saving of setpoints
e. real-time clock
3. Cycle control and management of the process image (PI)
The procedure for installing a new firmware with or without applications is identical to that of a firmware
update.
