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 an SNMP manager on a workstation while an SNMP agent runs on the devices themselves. In order to be able to integrate the network management into various HMI and SCADA systems with implemented OPC clients, it can be useful to incorporate an SNMP manager into the OPC server application. SAEAUT SNMP OPC Server provides such solution.
The SAEAUT SNMP OPC Server features
- From an 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 an OPC UA 1.01 wrapper that allows you to access all the data from SAEAUT SNMP OPC server even via the latest OPC standard called Unified Architecture (UA)

- Provides the Heartbeat functionality for monitoring devices which do not include SNMP Agents. This function shows the response time of a device as a special OPC variable
- Find tool, which allows you to search for a text within the 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 versions.
** Basic version has limited number of the devices(15), which can be connected to the server.
*** Basic version includes MIB Browser but without the 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 used effectively for system monitoring and network diagnostics.
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 you to get a basic information from devices that are unmanageable.
The manageable devices are able to provide the managing application with trap messages. These are sent without a request (e.g. in case some significant value is changed). It reduces traffic between the 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 the 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 a GUI. It is used to configure the address space of the SNMP OPC Server within a tree view containing managed and unmanaged devices, their variables (OPC items used for mapping of SNMP variables), alarms and simulation signals. It also contains a JScript editor to create scripts for preprocessing of OPC items.

The monitoring client is part of the configurator. It's able to monitor network devices and provide information about parameters selectable by a user. This information is displayed in well-arranged tables which contain not only the value itself, but also other useful information such as timestamps and quality of connection.
The built-in alarm system allows users to configure how critical values will be displayed by the server, using predefined alarm messages.
SAEAUT SNMP OPC Server allows you to further process data obtained from SNMP agents using J-Scripts. The server offers a simple built-in editor where the scripts can be modified and executed. This allows users to preprocess data on the server side before they are provided to clients.
SNMP variables received through SNMP protocol actually represent objects in the MIB database. The MIB database is comprised 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 the MIB browser is to request applicable IDs of MIB objects.
Besides standard online browsing features, MIB Browser provides Offline 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 the MIB file, which is usually delivered together with the SNMP device.
This module provides the feature of scanning computer networks 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
As well as 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 a 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 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
