Subject to alterations without notice

Warning!
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.

About this manual
D301174 1211 - BL20-ECO EtherNet/IP1-2
1.1 Documentation concept
This manual contains all information about the BL20 gateway for EtherNet/IP of the product series
BL20-ECO (BL20-E-GW-EN-IP).
The following chapters contain a short BL20 system description, a description of the field bus system
EtherNet/IP, exact information about function and structure of the gateway as well as all bus-specific
information concerning the connection to automation devices, the maximum system extension etc.
The bus-independent I/O-modules for BL20 as well as all further fieldbus-independent chapters such as
mounting, labelling etc. are described in a separate manual.
BL20 I/O-modules
