OPC is no longer an acronym. When OPC first released in 1996 it was an acronym for "OLE for Process Control", and was restricted to the Windows operating system. OPC is now available on other operating systems and enjoys significant adoption outside of process control. So, the original name (OLE for Process Control) is no longer appropriate and OPC changed from an acronym to a word. Thus, OPC no longer stands for anything (OPC is just OPC).
OPC is an industrial communication standard that enables manufacturers to use data to optimize production, make operation decisions quickly and generate reports. OPC enables plants to automate the transfer of data from a control system (PLC, DCS, analyzer, etc) to an industrial software application (HMI, Historian, Production system, Management system, etc). OPC is typically found in Level 3 networks and higher. Thus, OPC transfers process control data between the Control (Level 2) network and the Operations/Manufacturing (Level 3) network. It also exchanges data between the Operations/Manufacturing network and the Business (Level 4) network. In essence, OPC is the Modbus of the new century. It is not a replacement for low-level communication standards such as 4-20mA, Hart, Profibus, or Foundation Fieldbus. Rather, organizations use OPC in high-level communication.
A common analogy used to describe OPC technology is similar to that of a printer connected to a computer. The computer requires a printer driver in order to interface with the printer. Similarly, OPC is the driver installed on computers to help software applications interface with industrial data sources.
Automation & IT Professionals as well as a wide variety of engineers use OPC to help manage their process. OPC technology is used in a wide variety of industries including process control such as power, oil & gas, petrochemical, pulp & paper, etc. It is also used in discrete manufacturing such as automotives. It also is used in military applications.
OPC technology is based on a server / client architecture. The OPC Foundation helps define the standard through different working groups made up of many member companies.
OPCTI is the largest OPC training company in the world. OPCTI offers hands-on classes both in-person and online. Unlike other companies that offer vendor-biased information, OPCTI focuses strictly on training and does not sell its own products.
OPCTI’s comprehensive workshops provide automation professionals with a proven training program that enables them to quickly take on the challenging task of establishing a robust communication infrastructure. Each workshop is composed of various units that increase in complexity. In each unit, students first learn the theory followed by hands-on exercises that demonstrate common contemporary issues. Each unit has additional exercises to challenge even the most advanced students.
The Certified OPC Professional (COP) designation is endorsed by many OPC Foundation member companies. Holders of the COP designation have demonstrated proficiency with OPC technology, design architecture, installations.
OPCTI is an active member and a strong supporter of the OPC Foundation.
