Node configuration

hello, please i need help, i want to assign the payload (string 9570..) to the set rule

Not a great deal to go on there I'm afraid. We have no way of guessing what message that payload is on and whether your change node is receiving it directly or whether you need to save the payload and then use it in the change node.

there is any simple way to assign the slider output to the iotgat....../s7.reference.v

i put the topic iotgateway/write on the slider but i dont know how to choose the reference as a target thanks

I've already explained this in your other thread.

i've already did that, but still dont see the way that i can write to a specific tag since all output are an array with 4 variables
