Hello wewake; Siemens PLCs do not directly support Ethernet/IP (it is a protocol used by Rockwell Logix family of PLCs). Siemens PLCs support either Industrial Ethernet of Profinet. The protocols all use TCP/IP as a network layer, but cannot exchange data directly between CPUs of different manufacturers. So you would need a gateway between the Ethernet/IP CPU and the Siemens PLCs. Siemens recommends the Echochange Gateway: Communication between SIMATIC S7 and Allen-Bradley ControlLogix CPUs via Ethernet: Use of "Echochange" gateways Hope this helps, Daniel Chartier |

Hello wewake; The Softing/INAT webpages onthe Echochange gatweway give these technical specifications:
You probably need to add a special licence to be able to connect your 22 Ethernet/IP stations. Use the "Contacts" link in the webpage mentionned if you want to pursue this solution. Note that depending on the volume of data you want to exchange with the Siemens PLC one often used technique is toset one of the Ethernet/IP stations as data concentrator (it would collect all data from all the 22 Ethernet/IP stations) then you would iuse the gateway between that data concentrator to the S7 PLC. Hope this helps, Daniel Chartier |
