Overview
1. Overview
Figure 1: Block circuit dia ram
The module CAN-PN can link any PROFINET® IO-controller to a CAN network. The CAN-PN
ateway itself operates as a PROFINET IO-device with a maximum of 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. . a SIMATIC-S7.
The number of CAN participants is not limited by the ateway.
The CAN-PN module operates internally with an ARM® processor ERTEC200 type, which buffers
the CAN and PROFINET IO data in a local SDRAM. The firmware and confi uration data are kept
in the Flash. Parameters are stored by means of a serial EEPROM.
The CAN hi h speed (ISO 11898-2) compatible CAN-interface allows a maximum data-transfer
rate of 1 Mbit/s.
The 100BASE-TX PROFINET-IO interface is compatible to IEEE802.3 and runs with 100 Mbit/s.
The PROFINET-IO as well as the CAN interface are electrically isolated.
Accordin to standard, the PROFINET-IO interface is equipped with two RJ-45-sockets. An
Ethernet switch is inte rated in the ERTEC200.
CAN is connected via a 5-pin COMBICON sprin force plu .
The module can be confi ured via PROFINET IO confi uration tool, e. . the PLC SIMATIC
Mana er or the TIA Portal. No additional confi uration tools are required!

Starting Up
3. Starting Up
To start up the CAN-PN follow the instructions below.
Step Procedure see
page
Read the safety instructions at the beginning of this docu ent
carefully, before you start with the hardware installation! 5
Danger
Hazardous Volta e - Risk of electric shock due to unintentional contact with
uninsulated live parts with hi h volta es inside of the system into which the
CAN-PN is to be inte rated.
→
→
All current circuits which are connected to the device have to be
sufficiently protected a ainst hazardous volta e (SELV accordin to
EN 60950-1) before you start with the installation.
Ensure the absence of volta e before startin any electrical work.
1. Mount the CAN-PN module and connect power supply volta e CAN bus
and PROFINET-IO. 10
2. Please note that the CAN bus has to be terminated at both ends!
esd offers special T-connectors and termination connectors for external
termination.
Additionally the CAN_GND si nal has to be connected to earth at exactly
one point in the CAN network. All esd termination devices will provide a
correspondin contact.
For details please read chapter “Correct Wirin of Electrically Isolated CAN
Networks”.

3. Continue with the installation of the software, as described in the software
manual of the CAN-PN in chapter: 'Implementation'. -
