Supplier News

WONDERWARE has released a new DA Server called SI Direct. SI Direct is designed to replace Siemens Simatic Net middleware to connect to PLCs in the Siemens S7 family.

In addition to the DA server, ArchestrA device integration (DI) objects have been created to represent the device and network hierarchy when connecting Siemens S7 PLCs to the industrial application server.

Wonderware's DA servers are built using the ArchestrA DAS toolkit and offer enhanced communication diagnostics and performance. Wonderware's SI Direct DA server provides access to data within the Siemens S7 200/300/400 family of PLCs through a standard Ethernet network interface card.

The DI objects represent the network as well as the PLCs, providing the user with a hierarchical view of their connectivity. When used in conjunction with Wonderware's industrial application server, the DI objects allow users or systems integrators to configure, deploy and monitor servers from one centralised location known as the integrated development environment (IDE). Because the IDE centralises all systems and applications, users simply have to install the software on the industrial application server once, rather than installing the software on multiple separate computers. It also allows for online configuration and diagnostic capabilities.

When operated as a stand alone server, the SI Direct DA server enables the user to start, stop, configure, and monitor communications between the client and device using a single utility. Each server built with the toolkit provides the ability to access a set of diagnostics during runtime. The framework offers sorting capabilities, optimises communications, and supports the OPC 2.05 standard.

With a single development effort, every DA server provides connectivity between client applications based on Wonderware's SuiteLink protocol and OPC and DDE protocols running on the Microsoft Windows 2000 and Microsoft XP operating systems, as well as data devices supported by the specific translated protocol.

Wonderware's SI Direct DA Servers work with all FactorySuite A2 products, such as the industrial application server, InTouch visualization software, InTrack resource tracking software and InBatch production management software.
