Composer EWS Companion Will Release Shortly

The Composer Companion version of our Bailey DCS Simulator will release this summer. Composer Companion is intended as an high value but low cost add-on to the ABB Composer EWS tools you already use. With Composer Companion you can load and unload a simulated controller, via simulated CIU, just like you would when Composer connects to the real plant. With Composer Companion you can execute your CFG logic in a simulated environment, and MONITOR the relevant CAD sheets, just like with the real DCS, but before you take the chance to install the logic to the real DCS.



Simulate even the BIGGEST DCS Systems

Our Bailey DCS Simulator just got faster.. a whole lot faster. Even before this change, our simulator was the fastest in the market, but with this additional 8 X speed improvement (or more !!) we now expect that our simulator has the power to simulate almost all ABB Infi-90/Harmony DCS Systems that were ever installed.. all within a single PC and simulating at real time or faster (to 10X). Our performance limit is now well above 300,000 blocks and 100 controllers.. certainly miuch larger than most users will ever need.

Tenaris Operators Console Goes In-Service In Indonesia

This steel pipe plant had neglected the operator consoles in its control room for long enough. Half of the consoles were no longer were functional, and the engineering workstation no longer worked. However, we were still able to install a redundant pair of OPsCon Servers, plus additional OPsCon Clients, in a single site trip. After complete training, the Tenaris operators adapted to their new consoles, based on the GE Proficy iFIX HMI, and even before we left the Tenaris technical staff were able to make engineering modifications to their new consoles.



Batch-90 and UDF Support Added to Simulator

Previse is pleased to announce that our Bailey DCS Simulator, already the most comprehensive simulator for the ABB Infi-90/Harmony DCS Systems, now also supports both Batch-90 (and FC148 and FC219) and the User Defined Function set of blocks. This version also provides a sophisticated new Debugger to help you review your cost function.

Akzo Nobel Chemicals

Previse customer is pleased to announce that our industry leading Bailey DCS Simulator, for ABB Infi-90/Harmony DCS systems, will be released with support for ABB Batch-90 programs in early 2011.

Dominion Cove Point LNG Operator Training Simulator

As year end approaches, so does the in-service date for the Dominion Cove Point LNG plant operator training simulator. This OTS includes a plant process model from GSE that reads/writes 4600 field IO points to the Bailey DCS Simulator, and a pair of Emerson Delta V operator console servers with 10,000 console tags.

Operator Training for Packaging Corporation of America

Previse Bailey DCS Simulator has been selected by Honeywell as a core component of an operator training simulator for the Packaging Corporation of America in Georgia.

Honeywell Alaska

When the BPXA division of Honeywell needed to perform a stress analysis for the large and very distributed ABB/Bailey DCS installation at the Alaska BP gas pipeline, they selected the Previse Bailey DCS Simulator to help. A key problems were the need to simulate a total of 400+ controllers, including many of the older Net 90 COM/AMM and LMM modules. It would have been prohibitively expensive to build a real DCS to simulate data traffic, and no other software product in existence had the required capabilities. But with the Previse Bailey DCS Simulator, and some Previse expert assistance, Honeywell was able to perform the required data traffic stress analysis.



Operator Training Simulator (OTS) at V.C. Summer Nuclear

Our Bailey DCS Simulator is yet again selected as a core OTS component, this time for an OTS at the VC Summer nuclear power station in South Carolina. VC Summer specifically liked the fact that they would also be able to connect their EWS tools to monitor CAD sheets within the simulator.
