Variables and custom equations - error messages

[Bikey]

I am trying to configure my brake switch input, which I've used previously without issue. I want analog input 6 to read "1" if it receives voltage >10volts, otherwise I want it to output "0". But when I input the equation that I've used before - "if(VAR_0205>10,1,0) - I get this error message:

Custom equations that are used for regular variables cannot contain references to other variables. Use user variables to combine variables

I just switched to 8.5.239. What am I doing wrong/did you really make this change?

Hello,

You need to change the VAR_0205 to x.

Kind regards,

I can do that, thanks!

So this means I can only reference one variable in a custom equation, which is the input from that particular channel?
I am suddenly running out of user defined variables thanks to upgrading to 8.5.

In a user defined channel you can reference many variables. What you can't do is create an equation for analogue 1 to be analogue 2 for example.

8.5 is limited to 25 user defined channels.

Kind regards,

Thanks. Is there any way you can bump this up in the next sofware version, to like 50 user variables?
