A few months ago a customer and I met to discuss their Industry 4.0 & IIoT pilot project. We discussed technology options and ways to collect data from the existing manufacturing process. Options like reading the data directly from the PLC or setting up an OPC service to request machine data were discussed; however these weren’t preferable as it required modifying the existing PLC code to make the solution effective. “What I really want is the ability to capture the data from the devices directly and not impact the control of my existing automation equipment.” Whether his reason was because of machine warranty conflicts or the old adage, “don’t fix what ain’t broke” the general opinion makes sense.
Capture versus Control.
So then truly connected IIoT automation solutions that are “Ready for IIoT” need to support this basic concept of “Capture versus Control.” We have a strong portfolio of products with Industrial Internet of Things capabilities, check them out at www.balluff.com.
