I am using IBHohstec to connect to a Siemens u115 CPU. I could connect fine with the cpu. After still having problems with the system, I tried changing cpu's. I can not communicate with the new or old cpu now. I just get error 3042 when I try to connect.
IBHohstec error 3042

- Start date
Figured it out
After a couple of hours of working I found that the PC was communicating just fine with the PLC but would not load new programs. I ended up telling IBHosft to delete all files in the CPU even though I couldn't see any. It did and the standard files showed up and I could communicate and upload files just fine.
