SAEAUT SNMP OPC Server
control and monitoring of network and other devices, integration into your SCADA
Current version overview:
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.
The SAEAUT SNMP OPC Server features
- from SNMP point of view, it acts as a Network Management System
- implemented protocols SNMPv2c and SNMPv1
- implemented specifications OPC DA (Data Access) 3.0, 2.05, 1.0, OPC AE (Alarms and Events) 1.10
- the installation package contains OPC UA 1.01 wrapper that brings the possibility to access all data from SAEAUT SNMP OPC server even via the latest OPC standard called Unified Architecture (UA)
- the installation package contains OPC XML DA 1.01 wrapper which offers another way of communication with SAEAUT SNMP OPC server through Web Services
- manages and monitors unlimited number of devices with SNMP agents **
- the installation package contains a simple example of running DEMO configuration
- ability to define tags by using the object identification (OID) from MIB file e.g.: .188.8.131.52.4.1.26184.108.40.206
- supports standard SNMP commands GET and SET
- built-in MIB Browser (on-line) sends requests to SNMP manageable devices to get SNMP variables which correspond to objects in MIB database, providing the user with object IDs, data types and values ***
- built-in MIB Browser (off-line) for bwowsing SNMP variables from MIB files, provided with SNMP device ****
- ability to manipulate the acquired data by using JScripts which can be configured directly in the SNMP OPC server *
- IP Scanner module for scanning of computer network in a given IP range, in order to find connected SNMP devices *
- allows to receive SNMP TRAP, notification message from SNMP Agents
- logging of server events *
- configuration can be done in an user friendly configuration software
- allows to obtain information about manageable and unmanageable network devices through standard Ping command
- provides the Heartbeat functionality for monitoring of devices which does not include SNMP Agents. This function presents a response time of device as a special OPC variable
- Find tool, which allows you to search for a text within current configuration and immediately browse the occurences in user friendly views
- contains examples of OPC clients together with source codes in C# .NET, VB. NET, VB6
- Import from CSV files - reading OID and other information from CSV files
- Running as Windows NT Service if required ****
* These modules are available only in Extended and Professional version.
** Basic version has limited number of the devices(15), which can be connected to the server.
*** 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.
The main components of SAEAUT SNMP OPC Server
- Configuration tool
- Runtime application
- OPC UA wrapper
- OPC XML DA wrapper
- OPC DA 3.0 Test client (including the source codes in VB.NET and VB 6.0)
- Test client that communicates with SNMP OPC server through Web Services
- Electronic manual (English version)
In order to fulfill various demands of customers, the SAEAUT SNMP OPC Server is available in three editions: SAEAUT SNMP OPC Server Basic , SAEAUT SNMP OPC Server Enhanced and SAEAUT SNMP OPC Server Professional. The differences are shown in the following table:

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.

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