Transfer value on button

[hanjun941]

Hello,

So let’s say I have an input channel that is constantly changing its value, but I want the value be deducted by its own value which is saved in a calculated input channel when I click a button.

So let’s say at 1seconds the input 101 is 5
at 2seconds the input 101 is 7
I want it so that at second 1 if I click the button, the current value i.e. 5 is saved as a value in my calculated input channel 102 using the formula Val(101), I set input 101 formula to be Cnl(101)- Val(102)
Do you have any advice on how to configure the button so that it does that?

Thanks

Or would I need to purchase the automatic control module? Does it support send commands like on event? SetVal(Val(101),102)?

I’ve been trying to wrap my head around this, so basically can I set a formula in a calculated variable to only update when I click a button, I have tried setting the calculated variable which uses Val() to not active but it still updates constantly.

Thanks

Hi,

I think, you don’t need Auto Control Module for this purpose.
Create an output channel, and define this channel number for a button.
When button clicked, a command is sent, and a formula of the output channel is calculated.

The formula may be like this:
SetVal(102, Val(101))
where 101 is the input channel you need to save
102 is the input channel of the calculated real type that stores the saved value.

In case you need to calculate a difference, change the formula:
SetVal(102, Val(102) - Val(101))

Hello,

I tried that, but the send command asks me to input and value, when I put it to Send Command Now, nothing happens. What’s the difference between send command and send command now?

Thanks.

Hello,
Please provide a screenshot of the Output channels table.
