However, when I run RSLINX and I configure the DF1 driver (rs232) immediatly detect successfull configuration. But when I open RSLOGIC500 (Runing RSLINx), I can't see anything in RSWHO . I only see my workstation computer, and thats all. I called to Rockwell Hotline, and we try together but was the same. I reinstalled the sw but happens the same. Iam thinking that perhaps the problem is because I have S7 and WINCC in the same Laptop, and automatically in the startup WINCC start an utility Server, and RSLINX try to do the same but using his own software. Please If you have Idea contact me.
