- [Instructor] OPC stands for Open Platform Communications.…OPC name was originally referred to OLE for Process Control,…object linking and embedding for process control.…Both names are still used in the industry,…and mean the same thing.…The OPC Foundation is responsible for…the development and the maintenance of this standard.…OPC is the standard for secure and reliable exchange…of data in industrial automation and in other industries…like industrial alternative things.…
It ensures the seamless flow of information…among devices from multiple vendors.…OPC is implemented in a server/client pairs.…The OPC client and OPC server relationship…is a parent/child one, where the server is the parent…and client is the child.…So let's see what an OPC client means.…An OPC client is basically any device or software…that the data are going to, either to be collected,…analyzed, or to be sent somewhere else.…
An OPC server is a software application…that has been written to one of the OPC specifications.…An OPC server will respond to requests…
Learn about the components and networks involved at each level of automation: field level, control level, and management level. Explore the different devices involved, from the programmable logic controllers (PLCs) on the factory floor, to OPC software that give technicians insights into operations. Instructor Zahraa Khalil, an engineer and educator, also provides an overview of SCADA (supervisory control and data acquisition), an industrial control system architecture that enables supervision over large distances and multiple sites.
