Abstract
A mobile human machine interface for a monitoring operation of a spatially distributed control system in a factory or the like provides a location signal to a central processor holding the control program and relevant I/O data. Based on that location signal, the mobile HMI receives data relevant to the machines near its location. As the user moves through the factory, its location signal changes and the data and program which it executes changes accordingly. The user may identify him or herself to the mobile HMI providing for a second degree of discrimination in the type of data provided to the mobile HMI.
