i am using this formula

if (Val(110)<800)
{
SetVal(801, 32);
}

but it’s not working.
input channel is 110
output channel is 801, value is 32.
i want to read input channel value and want to set the value of output channel.
inbetween these 2 commands i want to put some delay.
can you please help me out ?

Thanks

is it possible to use it for output channel ?

in my case it is not working for output channel.
i would like to use for output channel to show that switch is pressed/ON.
