This document explains how to install, configure, and operate the Matrikon OPC Trender.
OPC is an open industry standard for communicating process control data between software packages and plant floor devices such as PLC and DCS systems. OPC stands for OLE for Process Control and uses Microsoft OLE standards to provide a path for process control data to pass.
• An OPC server is a source of process control data, which it retrieves from a piece of equipment and translates into OPC format so that it can be passed to an OPC client.
• An OPC client connects to an OPC server and retrieves process control data from it. The purpose of the OPC client is typically to analyze or display the OPC data.
The Matrikon OPC Trender is an OPC client that allows you to access and trend, or graph, historical and real-time data from OPC servers in line series on a high-performance graph.
The Matrikon OPC Trender requires at least one DA or HDA server as a source of process control data.
• Data Access (DA) servers are OPC servers that retrieve current values from a tag and can be used to pass the real-time data to the Matrikon OPC Trender. With a DA server you can retrieve the value for the tag at the current time.
• Historical Data Access (HDA) servers are OPC servers that keep a history of the values of tags and can be used to pass historical data to the Matrikon OPC Trender. With an HDA server you can retrieve the value for the tag over a specified time range or at a specified time.
