The leading industrial OEMs build products that have their own connectivity needs in terms of speed, security, ease of configuration, key alerts, etc. Over the last decade these OEMs built and promoted industrial communication protocols and drivers that were built in their labs addressing their unique product/ecosystem needs. This led to the proprietary devices and systems that are not always interoperable. The good news is that we are already in the middle of this huge shift towards standard protocols like OPC, MTConnect, etc.
