As seen in Automation World, manufacturers, vendors, and service providers are working diligently to understand the net impact of the Industrial Internet of Things (IIoT).
IIoT is disrupting manufacturing, starting with existing systems, and this is spurring initiatives, pilots, and studies across the world. While IIoT is a step in the future, it does beg the question for many manufacturers, “What about the Manufacturing Execution Systems (MES) that I have today?”
Its important to note that the MES is one part of the process, people and systems triangle of productivity. IIoT is a net productivity enabler and a complement, rather than a substitute, to MES. In fact, MES have been notoriously costly to implement with long execution schedules. However, we have seen where smart devices and cloud-based systems allow manufacturers to stand up line downtime and overall equipment effectiveness (OEE) within days without substantial investments - costing less than a monthly luxury car payment. These IIoT smart devices can even enable machines that are not network connected or include a Programmable Logic Controller (PLC).
This progress coincides with a greater demand for return on assets (productivity). On demand customization, in response to increased competition, has drastically changed how manufacturers are thinking about their lines and plants. This is only one example of changing customer trends resulting in higher productivity demands.
This shift in productivity disrupts all three aspects: people, processes, and systems, through the application of available technology. The catalyst for this improvement is access to data, a lot of data, in a steady and consistent manner. The MES layer is intended to accumulate and provide this data.
“I would like to get access to my plant data, but its too expensive with my current system.” – Discrete Manufacturer
“I am getting data from all my equipment. I like how it’s presented. But, it’s stale and I don’t trust it. Data seems to be manipulated before it’s reported up.” – Beverage Packager
“For every 10 process parameters, only one equipment parameter is logged.” – Process Automation Manager
These scenarios show the gaps that can be filled to positively impact productivity. These gaps exist in varying degrees across MES installations and this is precisely where IIoT comes into play to expand the capabilities of MES rather than replace it. Technological progress enabling IIoT ranges anywhere from smarter sensors and actors, to more reliable cloud infrastructures. IIoT in this sense is less of a disruptor, and more of a sign of progress along the continuum of technology.
To answer the initial question of “What about the Manufacturing Execution System (MES) that I have today?” - it is important to realize that it is less about substituting and more about complementing the MES with IIoT.
Call to action:
A properly-implemented MES can bridge the world of corporate IT and connect it to the near real-time world of automated operational technologies.
