!In order to prevent overvoltage damage due to thunder storm, unplug the device rom USB
and CAN be orehand.
!Never let liquids get inside the device. Otherwise, electric shocks or short circuits may result.
!Protect the device rom dust, moisture and steam. Remove all cables be ore cleaning. Clean
the device with a slightly moist, lint- ree cloth. Cleaning agents or solvents are not suitable.
!Protect the device rom shocks and vibrations.
!The device may become warm during normal use. Always allow adequate ventilation around
the device and use care when handling.
!Do not operate the device adjacent to heat sources and do not expose it to unnecessary
thermal radiation. Ensure an ambient temperature o 0°...50 °C.
!Do not use damaged or de ective cables to connect the device and ollow the CAN wiring
hints at the end o the manual.
!The device is intended or indoor use only.
!The operation o the device in hazardous areas, or areas exposed to potentially explosive
materials is not permitted.
!The operation o the device or medical purposes is prohibited.
!The CAN-PN is an industrial product and meets the demands o the EU regulations and
EMC standards printed in the con ormity declaration at the end o this manual.
Warning: In a residential, commercial or light industrial environment the CAN-PN may
cause radio inter erences in which case the user may be required to take
adequate measures.

Overview
1. Overview
Figure 1: Block circuit diagram
The module CAN-PN can link any PROFINET IO-controller to a CAN network. The CAN-PN
gateway itsel operates as a PROFINET IO-device with a maximum o 256 bytes input data and
256 bytes output data on the PROFINET IO bus.
The CAN-PN connects CAN modules with CANopen (CiA DS 301) or layer-2 (ISO 11898-1)
applications to e.g. a SIMATIC-S7.
The number o CAN participants is not limited by the gateway.
The CAN-PN module operates internally with an ARM processor ERTEC200 type, which bu ers
the CAN and PROFINET IO data in a local SDRAM. The irmware and con iguration data are kept
in the Flash. Parameters are stored by means o a serial EEPROM.
The CAN high speed (ISO 11898-2) compatible CAN-inter ace allows a maximum data-trans er
rate o 1 Mbit/s.
The 100BASE-TX PROFINET-IO inter ace is compatible to IEEE802.3 and runs with 100 Mbit/s.
The PROFINET-IO as well as the CAN inter ace are electrically isolated.
According to standard, the PROFINET-IO inter ace is equipped with two RJ-45-sockets. An
Ethernet switch is integrated in the ERTEC200.
CAN is connected via a 5-pin COMBICON spring orce plug.
The module can be con igured via PROFINET IO con iguration tool, e.g. the PLC SIMATIC
Manager. No additional con iguration tools are required!

Starting Up
3. Starting Up
To start up the CAN-PN ollow the instructions below.
Step see
chapter
see
page
Read the safety instructions at the eginning of this document
carefully efore you start with the hardware installation! - 4
1. Mount the CAN-PN module and connect power supply voltage CAN
bus and PROFINET-IO. 2.1 9
2. Please remember that the CAN bus has to be terminated at both
ends. esd o ers T-connectors and terminators. Additionally, the
CAN-GND-signal has to be grounded at exactly one point in the
CAN network. There ore the CAN termination connectors o ered by
esd have got a grounding contact.
A CAN device whose CAN inter ace is not electrically isolated
corresponds to the grounding o the CAN-GND.

3. Continue with the installation o the so tware, as described in the
so tware manual o the CAN-PN in chapter: 'Implementation'.
