A new approach of realizing derivative block in RT-BOX or launchpad ,is this idea correct?

Although there is a similar question in the forum:https://forum.plexim.com/9/why-is-there-no-derivative-block-in-the-component-library?show=9#q9

But the C-script contains the ‘currenttime’ so it’s not compatible with the RT-BOX and launchpad ,while there is already a PID block in the latest plecs software, so can we utilize the PD function ,setting the KP=0, and adjusting the deriviative filter coefficient to realize the derivative function?

But maybe using the memory block can also achieve the derivative function,but we have to run it in the fixed solver~

Hello

I have same question about derivative block to work with RT-BOX and Launchpad.

But I test two methods you proposed is still not working.

Do you have any idea about this function?
