Problema con un flow


mayse so is more clear

That looks like msg.payload.value[0] to me.

In that second example, Impostata looks like an array. If that is the case, you have to select a single value from that array.

i done so : return {payload : msg.payload.value[0]}; and i had the value correct to return tx , i have the last question how i can do setpoint value + incremento value cose i want send to s7 the result into a variabile of plc .and reset the value to 0 after sended i dont know if is possible ? my regards for the help

how i can see in dashboard this value ? -2 with a function ?

Not possible to do it within a function, you should use either a Dashboard text node, or a UIBuilder template.

Simplest way is to install the Dashboard nodes if you haven't yet, and take a text node. Check the documentation and the website, there are a lot of examples.
