Hello Amir; The DO are totally independant of the inputs, either used as standard or high-speed DI. So you should be able to use them in your program directly. Why do you ask, have you experienced a specific problem? You seem to think that D0 is available as Q0.0; not true, look at you HWConfig information for your CPU's integrated I/O. As you can see from the attached document, D0 starts at address Q124.0, D1 is located at Q124.1… You will find information on all 31xC CPUs in the following manual: SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Hope this helps, Daniel Chartier |
