Original Equipment Manufacturer. A company that manufactures a product (typically a hardware product) that is then duplicated with little or no changes as it is sold to many customers. IE: a company that makes printing presses is an OEM and sells to facilities that use the printing presses.

OPC Created Jul 16, 2015 (17:20)

Open Process Connectivity (OPC) is the name of a technology standard used to write to PLCs. OPC allows information exchange between gauges, databases, programmable logic controllers (PLCs), and more.

OPC Server Created Jul 16, 2015 (17:20)

An OPC Server is a software application that acts as an API (Application Programming Interface) or protocol converter. An OPC Server can connect to a device such as a PLC, DCS, and RTU or a data source such as a database or HMI to translate the data into a standard OPC format.

OPC-UA Created Jul 16, 2015 (17:20)

OPC Unified Architecture (OPC-UA) is a communication protocol for interoperability developed by the OPC Foundation. The Foundation's goal for this project was to provide a path forward from the original OPC communications model (namely COM/DCOM) to a cross-platform service-oriented architecture (SOA) for process control, while enhancing security and providing an information model.

 Using the OPC-UA module, Ignition acts as an OPC-UA server, serving data collected by its built in drivers to other Ignition modules, as well as third-party OPC-UA clients. -Wikipedia

OPC Tag Created Mar 23, 2016 (23:49)

Often referred to as just 'Tags', OPC Tags are Ignition tags that specify an OPC server and address which drives their values. The OPC address will be subscribed at the rate of the tag's scan class during configuration, and values written to these tags will be pushed to the PLCs.

Operating System Created Mar 23, 2016 (23:51)

Abbreviation(s):
  • OS

The underlying software that runs on a computer and provides the user an interface to that computer. Common examples are: Microsoft Windows MacOS X Linux
