switch

[wale]

Hi guys, i would like your asistances. i would like to incorporate an indicator (LED) on Smulated signal (sine wave) to shown that single phase supply is ON(working) when it is running.

I would also like to incorporate a switch at the amplitude to break/close the input into the Simulated signal.

i am currently making use of labview 7.0.

Thanks.

Are you talking about the Simulate Signal Express VI? If you are, I don't know what you mean by 'single phase power supply'. The Express VI has a phase input but that is not related to any power supply.

If you are using the Express VI and want to simulate turning the signal on and off, just do something like the code below.

hi Dennis,

thanks for your assitance. i will try and see how it works on the simulation.

However i need to incorporate an LED at the sine output (GRAPHICAL DISPLAY) to indicate that the signal in ON (GENERATED).

Thanks veteran.

If you want an additional indication of the signal besides the On/Off button, just wire an indicator up to the control.

I guess I don't really understand what the real issue is. You can't connect or disconnect a wire on the diagram. If you have a graph as an indicator, data always has to wired to it. The data can be an array that simulates a sine wave, an array of zeroes as in my example, an array of NaN, in which the graph will be blank, or an empty array, in which case the graph will not update. The latter can be done with the Relay Express VI.

hi,

Assuming i have three different input (numreic controls) to be controlled by a three way switch, with one input (numric control) to be my source at any particular time, how do i go about constructing the three way switch.

Thanks for the last insight.

Sorry for the spelling.

That would call for a case statement. And if you want a 3 position vertical switch, here's the example mentioned here converted to 7.0. A simple vertical slide could also be used.
