It’s almost critical to think of the problems users face when attempting to create an integrated system of multiple-vendor products and applications. Unfortunately, no single protocol is going to swoop in and save the day. It requires integrating multiple complementary protocols, each with individual strengths, to achieve the goal of a true enterprise system. Leading the way is the dynamic duo of OPC and Modbus.
As industry standards evolve and strengthen, those with wide adoption and proven interoperability will continue down the road of enterprise integration while others will fade into obscurity. System architectures will always involve a selection of protocols and standards. The key is choosing well-established, complementary protocols like OPC and Modbus that offer the best interoperability options.
