iDioo Posts: 19 Rating: (0)	Hello. I have 2 siemens S7 connected through profinet. How can i activate an output on the "slave" when there's a output on the "master"? Without using put/get ! I want the "embbed"/built-in profinet communication of Tia V14. I've checked the "I/Odevice" box on the slave but the master goes in error when there's no connection. Can someone help me?

Is ok the the Controller have a BF Error if you disconnect the IO-Device. Regards Christoph

I've searched a bit and didn't find any template for this.

Such a situation may be caused, for example, by an I device CPU in STOP mode that does not produce or consume any current data. Resolution: Check the state of the I device CPU or the state of the distributed IO system connected with the PN/PN coupler."
