Ariya Man Posts: 90 Rating: (7)	Hello, I get "BF" on my IM 153-2 while using a Profibus to each modules on an expansion rack in a "S7-300 Redundant System". Any idea how to get rid of that? Here is the link to download the project: And screen shots of HW-Config and NetPro is attached! https://www.dropbox.com/s/04mmlwm6dtyo0um/C_401_REV1.7.zip?dl=0 Any help is highly appreciated!

I have downloaded the same program to the exacte hardware in my privious project and it worked out fine but i have no idea what's the deal with this one! Speaking of "connectord" i'm using those fast connector which you dont need to cut the intetnal red and green wires. Can those connectors make any problem? The speed is 1.5 mbps

I realized in NetPro when I click on CPUs the "active connection" section is not "OK" as shown in the attached screensho! Do you know how I can configure that?
