Hello,

I have new project: to migrate s7-200 to s7-1200.

I have old electrical cabinet of water treatment room with s7-200 and button, switch, level regulators and temperature regulators.

So, I want to build a new electrical cabinet with s7-1200 cpu 1214c dc/dc/rly and HMI panel for displaying pumps, tanks and valves.

Can you help me to choose the best panel for this project?

Ok, I get it. This link shows the difference between somatic panel.

So, if I choose basic panel I can't use faceplate and symbol library which are my needs in this project. 

Is there any solution?
