OPC - OLE (Object Linking and Embedding) for Process Control :: The Industrial Interoperability Standard

OPC
Knowledge Base

Automation Media is dedicated to develop the awareness and understanding about interoperability in automation by providing best information about open specifications that standardize the communication of acquired process data, alarm and event records, historical data, and batch data to multi-vendor enterprise systems and between production devices. Production devices include sensors, instruments, PLCs, RTUs, DCSs, HMIs, historians, trending subsystems, alarm subsystems, and more as used in the process industry, manufacturing, and in acquiring and transporting oil, gas, and minerals.

API


API is Application Program Interface, which is a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer puts all these blocks together.

Most operating environments such as MS-Windows, most HIM/SCADA software, Historian Software etc, provide an API interface so that engineers/programmers can write applications consistent with the operating environment. Although APIs are designed for programmers, they are ultimately good for users because they guarantee that all programs using a common API will have similar interfaces. This makes it easier for users to learn new programs.

In engineering software, Application Programming Interface (API) is a set of software functions used by an application program as a means for providing access to a specific application or operating system's capabilities. Many OPC Servers offers API for user.
