Hello everybody,

I have here a HMI KTP 400 mono PN working with a s7-1200 214-1ag31-0xb0 and they were programmed with TIA V11.

Now I have exactly the same program but in TIA v13 but I'm using a KTP 400 basic (color) and a CPU 214-1AG40-0XB0 and they work fine.But I try to replace the old mono KTP for the new one (color) but I have some errors that some tags can't be written and some information doesn't apear in screen. It is possible that may occur some incompatibility with versions of TIA and firmwares?

Regards,

Nuno

Hi nunobnk,

Migration allows u to work with older versions of TIA. So migrate from V11 to V13. Now replace HMI by color version in TIA-WinCC. Test in simulation mode. If it works fine then only download to new HMI. HMI may request u for OS update.

Perhaps have a look at the article: [LINK]

Not all HMIs are compatible with all PLCs, all of the time.
The firmware version of the devices matter.

In some cases you have to permit the PUT/GET instructions.
Other times the structures of the DBs should not be optimised.
Note these when reading the linked FAQ.

Also note the answer I have given:

Hi Sachinpatke,

What you describe is exactly what I did before post here. But I still have the old 1200 (s7-1200 214-1ag31-0xb0 + HMI KTP 400 mono)  working in machine with V11 project, and I need a replacement for that HMI just in case of failure. I have here a KTP 400 "color" and I have in the machine a KTP 400 mono with the old 1200 I mentioned above, both were programmed with V11. Now  I only have TIA V13 to work on the new ones (PLC and HMI color). . Now I only have the color one to replace, but after the migration the problems I described in first topic appeard.

I have the alternative to change plc and HMI at the same time, but I want to avoid that situation!

Thanks William but I think it won't work well in my case. If you read the answer I gave to Sachinpatke you will se better my situation. I think the alternative I will have is to change the old plc and HMI mono to the new ones I have here in  V13 and then try to update the firmware of the plc to support the V13 version, if I'm right.
