Multiple inputs to trigger one digitial output

Hello,

Currently I have a digital output controlled by logic gates, which in turn energises a relay. I.e. When temperature reaches setpoint, relay energises

Is there any way I can use another input, so when a hall effect sensor detects a low RPM on a fan, this put the logic low to the relay, over riding the other inputs?

 

Regards, Ed

Hi Edh,

 

Currently I have a digital output controlled by logic gates, …

Is there any way I can use another input,

Well, add more logic gates!?

Best regards,
GerdW

Think I've sussed it using an implies gate, however I'm getting the "These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required.
The type of the source is 1D array of
Dynamic Data.
The type of the sink is double [64-bit real (~15 digit precision)]." error, simply a Boolean output to a output DAQ?

Hi Ed,

 

no code means: no help on your specific LabVIEW problem…

 

But when DDT wires are involved you are pretty much in trouble! 😄

Not sure what code you mean .. however below is an image, I'm simply trying to get the output of the logic gate to the output DAQ!

 

Below are my printscreens, surely the DAQ can recognise a T/F/1/0?

Hi Ed,

 

I'm talking about that code, which you only show images from.

What about attaching real code with your message (aka VIs)?

 

And what about really learning LabVIEW and trying to stay away from DDT wires and ExpressVIs?

Best regards,
GerdW
