The DATRAN OPC-UA Server is a protocol framework for enabling 3rd party applications to communicate with DATRAN using OPC-UA clients. DATRAN OPC-UA Server replaces OPC Data Access (DA). The DATRAN OPC-UA Server is built using the Unified Automation .NET SDK (Software Development Toolkit). Unified Automation are a leading provider of tools and services for OPC-UA technology.
Secure connections between the OPC-UA Server and the client application are created using certificates. It is possible to work without certificates if security is not an issue as the OPC-UA Server can create its own certificates (self signed).
DATRAN OPC-UA Server is typically used as a Microsoft Windows Service but can also be used as a standalone application for development and testing.
Little effort is required in the configuration of DATRAN OPC-UA Server with all settings performed in a single XML file. Security is provided through the use of OpenSSL Certificates.
Once configured, OPC-UA Clients can subscribe for the desired data tags with DATRAN-OPC-UA Server which then notifies the client when those tags change values.
DATRAN OPC-UA Server also supports the communications of RTU logged data from QTech RTUs. As RTU logged data is received by DATRAN in a batch, DATRAN OPC-UA Server streams the notifications to the OPC-UA Client in a way to ensure no data is missed.
The data streaming rate is configurable to allow for tuning to the Archestra system capability.
