Hi You can also use a DP-DP coupler to communicate between siemens plc(S7 300 or S7 400)and control logix plc . |

Since you want redundancy, there are some issues with communication with AB. DP-DP coupler and gateways may not work with software redundancy as it normally only supports ET200M as DP slaves. You can have ethernet open TCP communication to AB EWEB module. But you have to handle redundancy part in your program yourself which can be a bit tricky but possible. If you use 400H system then you could use either gateways or DP slave modules from any manufacturers. Most popular ones are from Prosoft. http://www.prosoft-technology.com/content/view/full/9593 http://www.prosoft-technology.com/content/view/full/7416 There are also other possibilities with modbus etc. |

Dear Amit, Wellwe have been in such a sitution before and whatwe did was that,downloaded the Prosoft configuration builder and then Installed it. You can download it from: http://www.prosoft-technology.com/content/view/full/10018 After thatwe downloaded the related CPU GSD File from Siemens Support (I used 317-2DP). I Configured the Siemens CPU port as Salve and Imported the siemens GSD file in the prosoft builder. As we configure the Simatic Hardware I got I/Q address for read and write on the link both in SIMATIC manager for Slave Profibus port and in Prosoft Builder for Prosoft port. The only key point is that Configured the data as 16 bytes read and write as I had to just transfer the digital signals status, Soat siemens side simply write the status of the Digital points to the Q Bytes of the Salve CPU i.e. For Status of I0.0 and to be mapped to Q256.0 It will be A I0.0 = Q256.0 and similarly on the prosoft sidewe mapeed the I256.0 to a digital status controller tag using Move command in ladder. Thus it all happened. For you since you need it to be redundant Iwouldsay that you may have to use two such connectoins and manage the redundancy in the software as Jose mentioned in reply. ----------------------- Umar Samad INTECH Process Automation |

New question published by Techspray is split to a separate thread with the subject Communication S7-1200 with Rockwell 1769-L33ER. Best regards |
