I'm trying to setup two S7-319 CPUs to communicate over profinet (currently using Profibus) which are both in the same project.
I watched a youtube video showing the steps.
In the slave CPU I set it to I-Device mode and setup input/output lengths.
Then generate the GSD file.
In the master CPU the newly created GSD device is added.
After I loaded both hardware configs it didn't work and I get bus faults.
I noticed that Step7 adds a "-1" to the end of the device name when added to the master CPU.
In Step7 under PLC->Verify names... the name of the slave CPU does not match because of the "-1" added.
If I try to remove the "-1" in the master CPU device then STEP7 warns that another device already has that name.
If I ignore that I load the config the slave CPU has major issues and the HMIs wouldn't talk to it anymore (over profibus). So I had to undo the changes.
Any ideas why?
I am using Step7, not TIA portal.
Thanks.
