MTConnect vs OPC UA

mtconnectIn the January issue of Modern Machine Shop, Josh Davids of DataXchange discusses the difference between two different, popular protocols. MTConnect and OPC UA are compared.

“Although OPC UA and MTConnect are both http-based protocols (which makes them usable on internet-enabled networks), the question why MTConnect exists often arises since OPC UA has been around for a while and has wide support throughout industry,” Davids said.

“If we view machine monitoring at a high level, it’s apparent that MTConnect is best-suited for equipment with standardized functions, such as CNC controls or other equipment that has known capability. OPC UA is generally best-suited for one-off integration projects that use programmable logic controllers (PLCs),” Davids continued. “Another difference is that OPC UA can be a read-write protocol, whereas MTConnect is read-only. Nothing can be written back to the machine.”

There is much more insight on why MTConnect and OPC UA are different in Davids’ contribution piece.
