Hi there,

I am a newbie at Twincat system. I do mostly work with AB. However, I will need to make a project at Twincat, so I am tryin to get used to TE2000.

When I write into a PLC variable and then read it again from TcHMI, it gives me the following output:

But actually the value is correct at PLC:

Does somebody knows a solution for this problem?

PS: TC3 project is in the attachment.

Update:I also added the jpegs in the attachment.

Your help will be much appreciated! Thanks.

Look at the following https://www.h-schmidt.net/FloatConverter/IEEE754de.html and enter 50.1 as IEEE value.
You will see that mathematically a slightly different value is stored (IEEE precision).
In the HMI you have a doube precission value as display, so here you see the "gap".

Anyhow, most people "round" the real value as nobdy is interessted in the n - th digit in the number.
