Push-Button Mode definition
Push-Button Mode. This mode is defined to support installation of a limited number of devices on one logical segment of a physical medium. There is no need for a specialised device for configuration, therefore each device implementing the push button mode shall include the means of configuration related to its application. The devices implement fixed parametrical functionalities as described in the corresponding application specifications. Each device is provided with the ability to be dynamically configured by setting the needed individual and group addresses and parameters. Exchange of parameters is also possible, but will be mainly local on the devices. At configuration time, the installer successively designates the devices the functions of which will be linked (therefore the name push button), the way he does it is manufacturer dependent. The exchange of configuration data occurring between devices, typically sensors and actuators, is made trough a single application layer service. Each sending Datapoint device acquires itself its unique group address. This address will be given to the receiving Datapoints using the pushbutton procedure.
