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!
