Introduction

General Information

Network Operational Performance Management is an important topic, as data communication bottlenecks have great impact on the bottom line and production servers. This software is a server for data acquisition which enables SNMP data to be available to any OPC-DA client, including data historian-based real-time performance management (RTPM) systems and OPC-DA compatible SCADA systems. It uses a fast and reliable data acquisition engine allowing massive real-time SNMP monitoring. Features include:

Scan of multiple devices;

Compatible with V1, V2C and V3 SNMP Devices;

Intelligent scan load control;

Statistical tags such as interface usage, error rates, broadcast and unicast rates;

Full support to Device TRAPS;

Data filtering (averaging);

Compliant with the OPC DA2 specification;

System Requirements

This OPC server has the following minimal system requirements:

Microsoft Windows NT4/2000/XP

Service Pack 5(NT4) / Service Pack 4(2000) / Service Pack 1(XP)

Intel/AMD processor @ 600MHz

128MB RAM

50MB Hard drive space

Network interface card (Ethernet)

Higher system hardware requirements may be necessary when scanning more than five thousand tags or when a large number of tags are scanned at a fast rate.

Server Overview

This server follows the requirements of the OPC specification to provide data access to an OPC client. The server is compatible with OPC Data Access (DA) version 2.0 of the OPC interface and it can be used to monitor every reachable SNMP device that implements SNMP V1 or V2C. The server core is heavily optimized to achieve high performance by measuring response times of every device and balancing server load to maintain the specified refresh rate for all devices. It is possible to customize scan parameters from each device, like the number of multiple variables that are read in the same SNMP request. This feature allows you to build the most optimized configuration for your network environment.

Tools Overview

XRatel SNMP OPC/DDE Server provides three tools to manage servers and data and 2 servers to manage data acquisition. These tools are listed below:

XRatel SNMP OPC/DDE Server - Server Configuration - This tool helps you to configure the SNMP Server. It allows you to indicate which devices and tags should be monitored.

XRatel SNMP OPC/DDE Server - Server Monitor - Allows you to manage SNMP Server, simplifying server reboot, configuration reloading and displaying statistics about it.

XRatel SNMP OPC/DDE Server - SNMP Server - This is the software responsible by data acquisition and delivery. In OPC licenses, it acts as an OPC server.
