Hello,

I have an installation of two 317 CPUs configured as redundant via PROFIBUS (with I/O redundancy) and an HMI (TP 270) connected with first CPU via PROFIBUS. Will the changes I do in first CPU (like donwload blocks or memory reset) be reflected in second CPU automatically? 

Topic closed because the question has been posted twice. The active topic can be found here:
