Hello

I work on a big project where I use a lot of HMI touch panels and ET200s CPU. Until now I used touch panels mp 277 10', but now I need to change it with new HMI TP 1200 comfort. For new panel I thing I will need  WINCC V13 comfort, but the problem is because I don't want to change the CPU. Now I configure the ET200s IM151-8 PN/DP CPU with Simatic step 7 professional V5.5. My question is can I use the same step 7 version, or I need to have new one. Would you like to tell me which version of software I need to have to work with same CPU and new HMI. Will the STEP 7 TIA Portal V13 professional is solution for both CPU and HMI.

Thank you in advance

Hello,

yes Step7 V13 professional is the right for the CPU.
For HMI + CPU you need Step7 V13 Professional and WinCC V13 Comfort.

Or you use the Proxy device in WinCC V13 then you can project the CPU in Step7 V5.5 and the HMI in WinCC V13.
