Use of open networks, distributed I/Os, and electronic components is one way of defining an MCC as intelligent.
Typically, intelligent systems have three things in common:
- Control is achieved through a microprocessor-based system
- Network technology is used to replace hardwiring
- Some degree of enhanced diagnostic or protective functionality is included.
While many associate these technologies with intelligence, another definition has nothing to do with the technology involved. In today’s competitive business environment, perhaps the definition of an intelligent MCC should be as simple as a unit that provides equivalent or greater functionality more economically. In other words, an intelligent MCC is simply an MCC that maximises the value of the components in a given application.
But how does one determine maximum value? Is it based on the cost of the equipment? That definition doesn’t take into account the total cost of the unit. In other words, the cost to design, specify, purchase, install, commission, operate, maintain, and upgrade an MCC are all calculated into the total cost of ownership.
Each individual in the chain is likely to define intelligence related to his or her perception of value. For example, consultants who design and specify equipment are interested in the reliability and performance of the components. A contractor may be primarily concerned with installed cost. A facility manager is likely to be worried about ease of operation and maintenance costs. And operations personnel are focused on the functionality and durability of the entire system. In other words, regardless of a person’s function, a truly intelligent MCC will optimize the value of the equipment specific to that function.
