Watch the video - 2nd part of the tutorial about MQTT publish/subscribe communication using OpcDbGateway. Please, see also the first part.


Check out a video showing usage of OpcDbGateway for IoT. It demonstrates the case of using the message transmission from the building automation system to an application using the MQTT subscribe client.


New video with short information about OpcDbGateway for application concertation and RAD has been published.


The latest version of the software for application integration - OpcDbGateway has successfully passed quality tests on the software portal FindSoft. It was awarded as Editor’s pick - "top software" for the quality, stability and above-average functionality in its class. Unlike previous versions, you can use a single installation file for x86 and x64 platforms.


The latest version 5.02 of OpcDbGateaway brings several improvements especially in the proprietary alarm system. This alarm system provides display of the current status of alarm sources, acknowledgment of alarms, and storing of parameterized alarm messages in the alarm history table in different languages. These messages may contain the current values of selected process variables in the births and deaths of alarm. They can be sent as SMS and / or E-mail as well.


The version 5 of products OpcDbGateway and SAEAUT UNIVERSAL OPC Server provides a number of improvements not only in both the runtime and configuration applications of mentioned products but also in the auxiliary jointly distributed applications. ...


OpcDbGateway is an universal platform enabling integration of complex or easy applications preferably by configuring instead of more laborious programming and for bridging of different data sources. SAEAUT UNIVERSAL OPC Server is a tool for easy development of dedicated OPC servers. Both products use common configuring and programming practices. One of most often usage of OpcDbGateway and SAEAUT UNIVERSAL OPC Server is logging of data from a monitored system – e.g. plant floor data from machines and devices. They both have also parameterizable logging of internal configurable or programmable functionality. Please see details to that in the new white paper.


Our new application SAEAUT OPC WebView enables easily visualise data from different devices. Communication with a device is provided by an OPC DA server. An appearance of the application in a web explorer is automatically adapted to the actual configuration of the OPC server address space. When using it together with our application OpcDbGateway, you will be able to visualise data also from more devices, even with those to which you do not have OPC servers.


We are proude to anounce a new product SAEAUT UNIVERSAL OPC Server dedicated to integrators and software vendor companies. It is, from the point of OPC DA, AE, OPC XML DA a OPC UA standards, readymade OPC server. You can configure (using delivered configuring application ) and program to that your own functionality using standard software development tools. It can be, for example, a communication driver for a device to comunicate with, or whatever software module cooperating with other applications using OPC interface. This product removes a need to develop own configuring application for your OPC server. Creating of your OPC server is easier comparing to different available OPC server SDK’s. Details to that you can find in a product description here.


OpcDbGateway ver.3.16 has enhanced accessibility to databases using OLE DB Provider for SQL Server. Compared with access to the MS SQL servers with ODBC driver, using of OLE DB Provider is not only more powerful but more universal. It accepts an amalgam of ODBC, ANSI, and SQL Server-specific Transact-SQL as valid syntax.
