Abstract
Disclosed is an industrial control device including a point-to-point backplane/point module architecture providing RIUP (Removal and Insertion Under Power) functionality where data communications between modules is maintained after the removal of a point module from the backplane. According to an exemplary embodiment, a backplane includes a plurality of bypass switches controlled by respective point modules, whereby data communicated bypass a removed point module interface and point-to-point data communications are provided to an inserted point module after an initial routine is executed by a microcontroller associated with the inserted point module.
