Terminator for unconnected physical signal outputs
Simscape / Foundation Library / Physical Signals / Sinks
Use the PS Terminator block to cap physical signal output ports that do not connect to other blocks.
Unlike conserving ports in physical modeling, or Simulink® output ports, unconnected physical signal output ports do not generate warnings. However, you can use a PS Terminator block for clarity, to indicate that the signal was not inadvertently left unconnected.
The block icon size allows you to connect the PS Terminator block to an open port without rerouting the adjacent lines:
I— Input physical signal, untyped
Input physical signal.
The port name is not visible in the block icon, but you can see this name in the underlying source file (accessible by clicking the Source code link in the block dialog box).
Behavior changed in R2019a
Prior to R2019a, this block did not propagate physical units.
If your model contains legacy blocks without unit propagation, use the Upgrade Advisor to upgrade your blocks to the latest version. For more information, see Upgrading Models with Legacy Physical Signal Blocks.
