control and monitoring of network and other devices, integration into your SCADA

Exploitation of SAEAUT SNMP OPC Server

The common way for managing industrial and network devices is to run SNMP manager on a workstation while SNMP agents run on devices themselves. In order to be able to integrate the network management into various HMI and SCADA systems with implemented OPC clients, it is very useful to incorporate SNMP manager into OPC server application. SAEAUT SNMP OPC Server provides such solution.

*** Basic version includes MIB Browser but without possibility to add new items to configuration.
**** Available only in Professional version.

How to use SAEAUT SNMP OPC Server?

SAEAUT SNMP OPC server allows operators to obtain the status information from network devices. Such information can be effectively used for system monitoring and network diagnostic.

However, not all networks are manageable through SNMP. For such cases, SAEAUT provides the possibility to configure OPC tags, implemented as a sort of “heartbeat”. This allows to get a basic information from devices that are unmanageable.

The manageable devices are able to provide managing application with trap messages. These are sent without a request (e.g. in case of some significant value is changed). It reduces traffic between SNMP agent and SNMP manager. The traps are fully supported in SAEAUT SNMP OPC server.

Configuration tool

The configuration tool is an application with GUI. It is used to configure addres space of the SNMP OPC Server within tree view containing managed and unmanaged devices, their variables (OPC items used for mapping of SNMP variables), alarms and simulation signals. It contains also a JScript editor to create scripts for preprocessing of OPC items.

Monitoring client

The monitoring client is a part of the configurator. It is able to monitor network devices and to provide the information about parameters selectable by a user. These kinds of information are displayed in well-arranged tables which contain not only the value itself, but also other useful information such as timestamps and the quality of connection.

Alarm administration

The built-in alarm system allows user to configure how critical values will be displayed by the server, using predefined alarm messages.

JScripts

SAEAUT SNMP OPC Server provides the possibility to further processing of data obtained from SNMP agents using J-Scripts. The server offers simple built-in editor where the scripts can be modified and executed. This allows user to preprocess data on the server side, before they are provided to clients.

MIB Browser

SNMP variables received through SNMP protocol actually represent objects in MIB database. The MIB database comprises of attributes (MIB objects) which can be used for the configuration, management and analysis of SNMP manageable devices. Each MIB object is identified by its ID. The main task of MIB browser is to request applicable IDs of MIB objects.

Besides of standard on-line browsing features, MIB Browser provides off-line MIB browsing (note that this feature is available only in Enhanced and Professional editions). This is achieved by loading the information about SNMP variables from MIB file, which is usually delivered together with SNMP device.

IP Scanner

This module provides the feature of scanning computer network in a given IP range, in order to find connected SNMP devices. After completing this process, all search results (IPs with SNMP devices) are available in the device panel so that the user can later select valid SNMP address from this list.

SAEAUT SNMP OPC Client

A simple OPC client which allows you to connect to SAEAUT SNMP OPC Server through standard interfaces DA 3.0, 2.05, and XML-DA 1.01. To simplify the process of connecting to the server, the client already contains predefined links for the most typical connection methods.

OPC Client applications source code

Besides of the above mentioned SAEAUT SNMP OPC Client, the installation package contains several example client applications, demonstrating the easy use of SAEAUT SNMP OPC Server and providing very good source of inspiration for the user.

Events logging

The purpose of event logging is to record the occurrence of significant events of SAEAUT SNMP OPC Server. The events are stored in a log file so that it’s possible to check and analyze them later on.

Find tool

SAEAUT SNMP OPC Server is able to manage and monitor very complex network configurations. In such cases you'll appreciate the Find tool, which allows you to search for a text within current configuration and immediately browse the search results in user friendly views
