Hello!
We are making an application using a Siemens S7-400 controller over profibus DP that need to be integrated to a weighing scale over Ethernet/IP.
The solution for this case is using a AB7671 gateway (Profibus DP Slave / Ethernet/IP Scanner). Do this work when using class 3 CIP messages in ethernet for the weighing scale?
Hi @Chanlucas,
Unfortunately, the Anybus Ethernet/IP Scanner only supports Class 1 connections for I/O data. It only supports class 3 connections toward the message router. There is no way to configure MSG Instructions. See page 24 of the Scanner Manual.
Best Regards,
Kyle
Hello Kyle,
My mistake, the communications are class 1 connection. The application covers a Siemens S7-400 controller with a weighing scale. The Siemens S7 is on a Profibus DP network and the weighing scale is on Ethernet/IP Class 1. The AB7671 works, right?
Yes, this is the correct device to connect an Ethernet/IP Adapter to a Profibus PLC. You will need the Connection Points for the Input and Output Assemblies in order to configure the Anybus Eth/IP Scanner. You can usually find these in the Adapters documentation, or in it’s EDS file.
