Hello kamal; Good that you hve no errors. But please study the warnings also, they are not at the same level as fatal errors, but they may give indications that you must follow if you want your conversion to be smooth. One example of an issue that came back to haunt in a S7-31xC migration is the fact that the integrated digital input/output addresses do not match between your old CPU 312C and your new CPU 314C-2PN/DP, so you will have to adjust (perhaps using the rewire function of Step7) everywhere these addresses have been used in the original CPU 313C program (for the integrated technological functions, for example). See the screenshot below, taken from the following document: SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Hope this helps, Daniel Chartier |
