Which of the following is NOT a listed communication protocol when defining a new IDAS I/O Server?

When defining a new IDAS I/O Server, it is important to understand the various communication protocols that are utilized for data exchange. In this context, the correct choice indicates that the MX protocol is not typically recognized as a standard communication protocol in this specific application.

OPC (OLE for Process Control) is a widely adopted standard in industrial automation, facilitating data interoperability between different hardware and software applications. It plays a crucial role in connecting process control and monitoring systems.

SuiteLink is another communication protocol delivering robust connectivity within the AVEVA (Wonderware) environment, enabling seamless data communication between different components of the system, especially in the context of the Wonderware application suite.

DDE (Dynamic Data Exchange) is also a communication protocol that allows applications to communicate and share data in real time, although it is considered less modern than OPC and SuiteLink.

The MX protocol, however, is not recognized as a standard for defining communication in IDAS I/O Servers. This distinction is important for anyone working with AVEVA Historian and similar technologies because understanding the applicable protocols can significantly influence system design and functionality.
