Subject to alterations without notice

Before commencing the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit.
Cover or enclose neighboring units that are live.
Follow the engineering instructions of the device concerned.
Only suitably qualified personnel in accordance with EN 50 110-1/-2 (VDE 0 105 Part 100) may
work on this device/system.
Before installation and before touching the device ensure that you are free of electrostatic
charge.
The functional earth (FE) must be connected to the protective earth (PE) or to the potential equal-
ization. The system installer is responsible for implementing this connection.
Connecting cables and signal lines should be installed so that inductive or capacitive interfer-
ence do not impair the automation functions.
Install automation devices and related operating elements in such a way that they are well
protected against unintentional operation.
Suitable safety hardware and software measures should be implemented for the I/O interface so
that a line or wire breakage on the signal side does not result in undefined states in the automa-
tion devices.
Ensure a reliable electrical isolation of the low voltage for the 24 volt supply. Only use power
supply units complying with IEC 60 364-4-41 (VDE 0 100 Part 410) or HD 384.4.41 S2.
Deviations of the mains voltage from the rated value must not exceed the tolerance limits given
in the specifications, otherwise this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating
modes of the automation devices. Unlatching the emergency-stop devices must not cause
restart.
Devices that are designed for mounting in housings or control cabinets must only be operated
and controlled after they have been installed with the housing closed. Desktop or portable units
must only be operated and controlled in enclosed housings.
Measures should be taken to ensure the proper restart of programs interrupted after a voltage
dip or failure. This should not cause dangerous operating states even for a short time. If neces-
sary, emergency-stop devices should be implemented.
Wherever faults in the automation system may cause damage to persons or property, external
measures must be implemented to ensure a safe operating state in the event of a fault or
malfunction (for example, by means of separate limit switches, mechanical interlocks etc.).
The electrical installation must be carried out in accordance with the relevant regulations (e. g.
with regard to cable cross sections, fuses, PE).
All work relating to transport, installation, commissioning and maintenance must only be carried
out by qualified personnel. (IEC 60 364 and HD 384 and national work safety regulations).
All shrouds and doors must be kept closed during operation.

BL20 Philosophy
D301141 1211 - BL20-ECO DeviceNet™2-2
2.1 The Basic Concept
BL20 is a modular I/O system for use in industrial automation. It connects the sensors and actuators in
the field with the higher-level master.
BL20 offers modules for practically all applications:
Digital input and output modules
Analog input and output modules
Technology modules (counters, RS232 interface...)
A complete BL20 station counts as one station on the bus and therefore occupies one fieldbus address
in any given fieldbus structure. A BL20 station consists of a gateway, power distribution modules and I/
O modules.
The connection to the relevant fieldbus is made via the bus-specific gateway, which is responsible for
the communication between the BL20 station and the other fieldbus stations.
The communication within the BL20 station between the gateway and the individual BL20 modules is
regulated via an internal module bus.
Flexibility
All BL20 stations can be planned to accommodate the exact number of channels to suit your needs,
because the modules are available with different numbers of channels in block and slice design.
A BL20 station can contain modules in any combination, which means it is possible to adapt the system
to practically all applications in automated industry.
Compactness
The slim design of the BL20 modules (standard gateway 50.4 mm / 1.98 inch, ECO gateway 34 mm/ 1.34
inch, standard slice 12.6 mm / 0.49 inch, ECO slice 13 mm / 0.51 inch and block 100.8 mm / 3.97 inch)
and their low overall height favor the installation of this system in confined spaces.
Easy to handle
All BL20 modules of the standard line, with the exception of the gateway, consist of a base module and
an electronics module.
The gateway and the base modules are snapped onto a mounting rail. The electronics modules are
plugged onto the appropriate base modules.
The base modules of the standard line are designed as terminal blocks. The wiring is secured by tension
clamp or screw connection.
The electronics modules can be plugged or pulled when the station is being commissioned or for
maintenance purposes, without having to disconnect the field wiring from the base modules.
The ECO electronics modules combine base module and electronics module in one housing. All BL20-
ECO modules can be used with the standard products with tension clamp connection technology.
Note
The gateway is the only fieldbus-dependent module on a BL20 station. All other BL20
modules are not dependent on the fieldbus used.

BL20 Components
2.2 BL20 Components
2.2.1 Gateways
The gateway connects the fieldbus to the I/O modules. It is responsible for handling the entire process
data and generates diagnostic information for the higher-level master and the software tool I/O-
ASSISTANT.
ECO-Gateways
The BL20-ECO gateways enlarge the product portfolio of BL20. They offer an excellent cost/
performance ratio.
Further advantages of the BL20-ECO gateways:
Low required space: width 34 mm/ 1.34 inch
Integrated power supply
Can be combined with all existing standard modules (with tension clamp connection technology)
and ECO modules
Simple wiring with "Push-in" tension clamp terminals and DeviceNet™-connection via Open Style
Connector with a possible wire cross section of up to 2,5 mm²
Automatic bit rate detection
Setting of fieldbus address and bus terminating resistor via DIP-switches
Service interface for commissioning with I/O-ASSISTANT (without PLC)
Gateway with Integrated Power Supply
All standard gateways BL20-GWBR-××× as well as the BL20-gateways for DPV1 and Ethernet (BL20-GW-
DPV1, BL20-GW-EN, BL20-GW-EN-IP, BL20-PG-EN and BL20-PG-EN-IP) offer an integrated power supply
unit for feeding the gateway and the connected I/O modules.

BL20 Philosophy
D301141 1211 - BL20-ECO DeviceNet™2-4
It is not necessary to supply each individual module with a separate voltage.
Gateways without Power Supply
2.2.2 Power Distribution Modules
The power supply for gateways and I/O modules is fed to the power distribution modules; therefore, it
is not necessary to supply each individual module with a separate voltage.
Figure 2-2:
Gateway
example:
BL20-GWBR-
DNET
Note
The gateways without integrated power supply unit need an additional power supply
module (bus refreshing module) which feeds the gateway an the connected I/O modules.

BL20 Components
2.2.3 Electronics Modules (Standard Product Line)
The standard electronics modules contain the I/O-functions of the BL20 modules (power distribution
modules, digital and analog input/output modules, and technology modules).
They are plugged onto the base modules and are not directly connected to the wiring and can be
plugged or pulled when the station is being commissioned or for maintenance purposes, without
having to disconnect the field wiring from the base modules.
2.2.4 ECO Electronics Modules
New ECONOMY modules with a high signal density and exceptionally low channel price expand the
BL20 I/O bus terminal system.
Depending on type, up to 16 digital inputs and outputs can be connected on only 13 mm. This high
connection density considerably reduces the mounting width required for typical applications.
All advantages at a glance:
Space saving thanks to 16 channels on 13 mm/ 0.51 inch width
Cost saving thanks to electronics with integrated connection level
High signal density
Tool-less connection via "push-in" spring-type terminal technology for simple and fast mounting

2.2.5 Base Modules
The field wiring is connected to the base modules. These are constructed as terminals in block and slice
designs and are available in the following variations with either tension clamp or screw connections: 2-
/3-wire (2-channel), 4-wire (2-channel) and 4 x 2-/3-wire (4-channel).
