Remember when electricity was an accounting job? Remember when plant tasks were mostly maintenance? Remember when process control was just in isolated loops? For many, those memories are yesterday's and today's—not to mention many difficult days to come. For others, it's an old and isolated perspective that's rapidly shrinking in their rearview mirrors, as they coordinate their increasingly digital process, plant and power controls to various degrees and in combinations of twos and even threes that can cooperate to achieve new levels of efficiency, optimization and performance. In past years, power distribution/conditioning and building management/automation systems…
