With the function "Send value, variable” two adjacent channels of the binary input are used and configured together. The prerequisite for this function is that the "Pairwise” option is selected in the device settings for the adjacent channel concerned.
“Function of channels A + B” parameter
With the function "Send value, variable,” a changeable value of a defined data type can be sent. The value is changed either by pressing the push-button several times or automatically when the push-button is pressed for a long time. The step size of the value changes, the length of the press of the push-button and limit values can be set. In addition, the value can be sent cyclically. Since this is a 2-button function, the value is adjusted up with one of the two connected push-buttons and down with the other.
Application example
This function can be used, for example, to set the target temperature of a room temperature controller using push-buttons.
