OPC Server

Introduction

OPC is a published industrial standard for system interconnectivity. The OPC specifications are maintained by the OPC Foundation. The purpose of OPC is to provide a standards-based infrastructure for the exchange of process control data.This data is available through different connections such as serial, Ethernet, or even wireless transmissions. Different operating systems like Windows, UNIX, DOS and VMS, are used by many process control applications. OPC Data Access, or just OPC DA, provides a standard way to access real-time data from process control hardware and software. OPC Data Access, or OPC DA, provides access to real time process data. Using OPC DA, one can ask the OPC server for the most recent values of flows, pressures, levels, temperatures, densities, and more. The most common clients of an OPC server are SCADA and GIS systems. Infinite has implemented the OPC DA specification in an OPC server for the SCOM-100 series.

Typical application

Features

• Conform to OPC Data Access specification.
• 4 different tag types: Analog Input, Digital Input, Digital Output and Counter.
• Supports the full device configuration consisting of an SCOM-100 base unit and a full set of I/O expansion modules.
• No fixed IP or VPN network addresses are required for the SCOM-100 devices. Remote SCOM-100 stations connect via GPRS to a fixed IP, TCP/IP port of the OPC server.
• Standard version supports 1000 tags.
• Seamless integration to popular SCADA software systems.

Hardware requirements

• Personal computers running Microsoft Windows XP or Windows 7.
• TCP/IP local area network.
• Serial RS232 port or a USB to serial adapter, 9600 to 115200 bps.
• A Sierra Wireless® GSM/GPRS MODEM.
