Why can't I connect my Simscape circuit to a PS-Simulink converter -- only a dashed red line appears?

I have an electrical circuit driven by a controlled current source. I gather that, to view a voltage at a node, I need to connect a PS-to-Simulink converter. I've placed a couple on the diagram, but when I attempt to drag a line from an existing line to the input of the converter, only a dashed red line appears. Connecting the converter to a scope works. I'm also in trouble on the input end, where I thought I'd need to drive the current source via a Simulink=to-PS converter which in turn takes its input from a step generator. Again, attempting to drag a line from the converter to the triangle-marked port on the constant current source results only in a dashed red line.

Hi, George,
To view the voltage at a circuit node, you should use the Voltage Sensor block:
In the Controlled Current Source block, you can see that the 'S' port has a '^' shape, which represents Simulink signal. Therefore, you can directly connect the Step block to the 'S' port without using Simulink-PS Converter.
Thanks,
Qu

1) Double slick the 'Capacitor' block;
2) Click the 'Variables' tab;
3) Select the 'Override' check box;
4) Type a new number into the 'Beginning Value' field and change the unit, if desired;
5) Click 'OK'.

Hi there, I have the same problem. However, even I've tried to used both ps converter and voltage/current sensor, seem it doesn't work properly. It just shows a dash-red line so I can't connect to a scope. I'm using Matlab 2017a. Can you help me pls???
