Hi!

I have an application to control a temperature through a Logo8! + KTP400 system. I'm using TIA Portal V18 and LSC 8.2.

It includes a PT100 connected to the Logo through a AM2 temperature input module and using 3 digital outputs to control heaters.

I need that the KC, TI and SP from the PI controller to be set through the KTP400. The PI controller output is fed to a PWM controlling the three outputs.

I'm not managing to input the KC, TI and SP from the KTP400 project to the Logo one, could you give me any hint on this?

Thanks!

Thank you very much for taking the time to set up that sample project!

It finally managed to complete most of the project, but now I'm struggling with this issue:

- The PT100 is read in the Logo and scaled into an INT memory space multiplied by 10

- I want to show the value and trend graph on the KTP400 but it would be best to have it as a real value with a decimal

Is there any way I can read the value on the KTP through the VM memory mapping (this already is working) and scale it to a real value with a decimal place?

Thanks!

Hi,

I hope i understand right. You can use the I/F-function block like this way:

That worked great!

Thank you very much for taking the time to explain!
