Invensys' Wonderware Business Unit Announces Release of DAServer for Modbus Serial Devices

October 092003
First Serial Communications Protocol DAServer Built with ArchestrA DAS Toolkit

LAKE FOREST, Calif., Oct. 9, 2003 -- Wonderware, a business unit of Invensys Systems, Inc., today announced the release of a new DAServer (DataAccessServer) based on the Modbus(R) serial protocol. The Wonderware DAServer for Modbus Serial Devices is the first serial communications interface to be built with Invensys' ArchestrA DAS Toolkit. All previously released DAServers have supported Ethernet-based protocols.

DAServers are Wonderware's next-generation I/O servers built on ArchestrA technology, which offer enhanced communication diagnostics and performance. Wonderware DAServers are designed to provide simultaneous connectivity between plant-floor devices and client applications based on Wonderware SuiteLink, DDE and OPC protocols, as well as the Modbus Serial protocol with this latest release.

"The DAServer for Modbus Serial Devices is distinct from all of the preceding DAServers produced by Wonderware because it is the first to support a serial protocol," said Tim Black, device integration manager at Wonderware. "The Modbus protocol is the first serial protocol we chose to support because it is one of most widely accepted de facto standards today."

The ArchestrA DAS toolkit used to create the new Modbus DAServer is designed to make building DAServers easier through the open ArchestrA software architecture. Using this toolkit, Wonderware, other Invensys companies and third parties are building DAServers, which are next-generation plant communications interfaces built on ArchestrA technology.

The Wonderware DAServer for Modbus Serial Devices was specifically tested with the Quantum, TSX Momentum and Modicon(R) Micro controllers.
