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

Question

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?

Answer 1

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