1Safety Information
Please observe the safety information given for your own and
other people's safety. The safety information indicates possible
hazards and provides information about how you can avoid
hazardous situations.
The following symbols are used in this manual.
!
Caution, indicates hazards and sources of error
i
Gives information
Hazard, general or specific
Danger of electric shock
1.1 General
The DP/CAN coupler is only used as part of a complete system.
!
The operator of a machine system is responsible for observing
all safety and accident prevention regulations applicable to the
application in question.
During configuration, safety and accident prevention rules
specific to the application must be observed.
Emergency OFF facilities according to EN 60204 / IEC 204
must remain active in all modes of the machine system. The system
must not enter an undefined restart.
Faults occurring in the machine system that can cause
damage to property or injury to persons must be prevented by additional
external equipment. Such equipment must also ensure entry into a safe
state in the event of a fault. Such equipment includes electromechanical
safety buttons, mechanical interlocks, etc. (see EN 954-1, risk
assessment).
Never execute or initiate safety-related functions using the
operator terminal.

1.2 Restriction of access
The modules are open equipment and must only be installed in
electrical equipment rooms, cabinets, or housings. Access to the
electrical equipment rooms, barriers, or housings must only be
possible using a tool or key and only permitted to personnel
having received instruction or authorization. See also Section 0.
Only authorized persons
must have access to the
modules!
1.3 Information for the user
This manual is addressed to anyone wishing to configure or
install the DP/CAN coupler.
It is intended for use as a programming manual and reference
work by the configuring engineer. It provides the installing
technician with all the necessary data.
The DP/CAN coupler is intended for use with a PROFIBUS DP
network only. For that reason, the configuring engineer, user, and
installing technician must observe the standards, safety and
accident prevention rules applicable in the particular application.
The operator of the automation system is responsible for
observing these rules.
1.4 Use as intended
The DP/CAN coupler must only be used as a communication
system as described in the manual.
1.5 Avoiding use not as intended!
Safety-related functions must not be controlled via the DP/CAN
coupler alone.

2Installation and Mounting
The DP/CAN 300 coupler must be installed according to VDE
0100 IEC 364. Because it is an “OPEN type” module, you must
install it in a (switching) cabinet. Ambient temperature: 0 ºC – 60
ºC.
Before you start installation work, all system components
must be disconnected from their power source.
Danger of electric shock!
During installation, application-specific safety and accident
prevention rules must be observed.
2.1 Vertical and horizontal mounting
The modules can be mounted either vertically or horizontally.
Permissible ambient temperature:
0 to 60 ºC

3System Overview
3.1 Application and function description
The DP/CAN coupler from System Helmholz GmbH allows you to
connect any CAN stations to the PROFIBUS DP.
The DP/CAN coupler must be parameterized as a PROFIBUS
station in the Hardware Configurator. The necessary GSD files are
supplied with the device.
The PROFIBUS side is configured as a DP slave. The interfaces
meet EN 50170 and are electrically isolated. The baud rate of
9.6kBaud to 12Mbaud is detected automatically. The size of the
input and output information does not exceed 320 bytes.
The CAN bus interface meets ISO/DIN 11898-2 and is electrically
isolated.
The DP/CAN coupler can send and receive any CAN messages,
both CAN 2.0A (11bit) and CAN2.0B (29bit). You can define
messages with a fixed identifier whose data is always visible as an
I/O image in the PROFIBUS. As an alternative, the DP/CAN
coupler has a transmit and receive buffer for any CAN messages.
