Industrial automation systems are performing

The advantage of this level of modularity extends well beyond the initial deployment, however. In the longer term, upgrading the level of performance is simply a matter of replacing the processor module – not the entire subassembly. This saves money, and minimizes unforeseen impact on the way in which the module as a whole interacts with its surroundings.

In the locomotive example mentioned, the COM Express processor module can be upgraded without affecting the connection to the engine I/O residing on the carrier board – reducing costly and time-consuming recertification and testing. The modularity of COM Express gives a whole new meaning to “technology insertion.”

Because of this modularity advantage, COM Express can substantially extend the useful life of key elements within critical infrastructures – a valuable benefit for industrial applications such as oil and gas, energy, and transportation. This is especially true when it comes to leveraging commercial technologies – often referred to as Commercial Off-the-Shelf (COTS).

In the past, vendors often used special niche and proprietary components on their products. However, for many of these component vendors, the long-term commitment to ensuring the continuing competitiveness of these products – with its requirement for extensive investment in R&D – meant that such components often had relatively short useful lifetimes, and didn’t benefit from the support of well-funded programs to minimize the impact of obsolescence.

Commercial products, however – such as those from Intel and AMD – could be expected to benefit from a development road map that would see successive generations of products emerge into the market, each compatible with its predecessor and each capable of delivering new levels of performance. This constant “upping the game” presents a real opportunity for users of COM Express technology – and it is an opportunity that modular architectures leverage to the maximum, enabling the Internet of Things (IoT) to become a practicable reality.
