Hi, Because Ethernet IP is not complete OPEN, you need a Gateway to get the SIMATIC standard Industrial Ethernet talk to the Allen Bradley SLC500 and vice versa. There is a example where this is shown in a pdf (from adobe Link: Communication between SIMATIC S7 and Allen-Bradley ControlLogix CPUs via Ethernet: Use of "Echochange" gateways |

I hope that the answer will help, if you have still questions, don't hesitate to ask me. |

Thanks. Are you sure is possible communicated also with SLC500,because the brochure talk about Control Logix 5000. Regards. |

Hello, I am not sure because I am not so into the AB stuff. But I checked the HP of INAT, the manufacturer of the ECHOCHANGE Device and found also the SLC 500 PLC in the list of useable PLCs. Please see for yourself: INAT Stay calm. |

Hi, I had also a try for ethernet communication but then with a ML1100 and a S7.  And as Late mentions Ethernet/IP (Ethernet/Industrial Protocol) is a closed protocol but could, in theory, be implemented as a self written driver in your Siemens controller. (Don't do it!) Both PLC were communicating to each other but could not understand each other, like two persons speaking a complete different language without having a common language. There are white papers available via www.odva.org. Here is a linkto EtherNetIP Example Code Freeware. If you have an analyzer like Ethereal even the Ethernet/IP stuff is shown cleary.  Note: Ethernet/IP is a part of Common Industrial Protocol (CIP) which makes it possible to "surf" with RSLinx over the different networks (a.o. DeviceNet and ControlNet) and discover thenetwork nodes.  There is also another "protocol converter" which I use sometimes, it's the Data Station Plus from Red Lion Controls, but I haven't use it yet for Ethernet/IP to ISO-on-TCP.
