As I can read from the help, this function works only on S7-300/400 cpus, so seems to be not possible. But then, i've found a previous project made by another programmer, that use KTP600 and 1214C where this function it's implemented and fully working. As you can see from the images attached, in the first one, in the hmi link page it show the cpu rack and slot information. And in this project, if I try to use the ChangeLink function with a pushbutton i can select the "EV300" link. In the second project, when I create the link between cpu and hmi (here it's used a KTP400 but i've test also with KTP600, also comfort panel) it show different information as you can see from the second image. And when che ChangeLink function is selected, under "Link" nothing is available.. Suggestions ? Is it a king of bug? Or is there a way to got it working even with 1200 cpus ?

Same project, same istruction, but now it works. Also in the help, under the ChangeLink function it says that 1200 cpus are supported, but then in v12 they are not supported anymore... Anyone can explain that ?
