How can I send "else do nothing"?

[Klaus]

Command value in a feedback process:

{{if([@d20]==1,2,do_nothing)}}

(if digital join 20 is 1, then send value 2, else do nothing)

How can I express this?

How about:

 

if([@d20]==1)  sendValue(2) 

 

or perhaps just:

 

 if(d20==1) sendValue(2);

 

Assuming there is a send value function as I am not sure of the context in which you want to do this

Math expressions can only result in numerical values that are sent when the command is fired. You cannot make a "send or not send" decision using math expressions.

Instead, you would need to use some JavaScript.
In the command value, put simply this: [@d20]
Then tick the "javascript sends command" option.
Then in your JS do this:
if (data == 1) CF.send(system, "2");
