Connecting mathscript node to continous transfer function in CDS loop

[ramyama]

PID speed control of DC motor

Hi,

Could you please tell me how the mathscipt node has been connected(indicated by the pink arrow) to the continuous transfer function as shown in the diagram? 

The output of PID is connected to the TF in which I have defined the model of DC motor. When I try to connect the mathscipt node to the TF, I am unable to find another input node. 

Kindly help me out.

Thanks,

Hi ramyana,

It has been connected by the pink wire.

(Atleast I guess so, but you can verify this using the AutoCleanup function from the menu…)

Hi GerdW,

Thanks for your reply. Yes that's right. It has been connected by the pink wire. But the transfer function is of continuous type with just one input. So how is it that the pink wire is also connected to the transfer function along with the output of PID?

Regards,

Hi ramyama,

according to this old LabVIEW help this function has three inputs…
