Abstract

A system and method is disclosed for configuring a group of mobile field devices using a configuration device (an HMI) is provided. In particular, the HMI is programmed to configure identically programmed field devices that are arbitrarily arranged in an application-dependent formation by defining and providing configuration parameters to the devices via wired and/or wireless communication. In particular, the HMI assigns a unique identifier to respective robots as a function of the position of the robot within the formation or the layout of the environment. Accordingly each robot can be efficiently configured by the HMI to operate independently yet as a coordinated member of the group and without requiring the robots to be placed in specific positions during the initial deployment. This obviates the need for constant independent control commands for each robot by a central controller or providing a customized control program to each robot during deployment.
