Download CPU 4.0 program into a 4.1 hardware

HI there, 

I would like to check something regarding the CPU with firmware version 4.1.

I notice that i am able to download a program which has CPU 4.0 configured in the TIA V13 SP1 into a hardware with the firmware version of 4.1. Is this normal? This was done by mistake previously but i would like to know why there is no any message indicating the difference? What will be the effect if done this way? Any short/long term effect?

What is the difference?

Is there any effect?

So far i notice there is no problem.

Can anyone advice on these?

Split from S7-1200 Firmware V4.1.

Hello karthhikk,

I would like to know why you stay in this gray zone?

You just have to save your project with a new name and change the CPU to firmware 4.1.

As you can see in "Compatibility information", there is no major impact to go from 4.0 to 4.1.

It is not the case if you do the inverse.

You will be able to see the major difference in "Compatibility information".

Best regards,
