timesDistributed Control System (DCS)
A distributed control system (DCS) refers to a control system usually of a manufacturing system , process or any kind of dynamic system , in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each c omponent sub - system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring. DCS is a very broad term used in a variety of industries, to monitor and control distributed equipment

Topic: HMI Operator Interfaces
The InTouch SQL Access Manager add-on program is designed to easily transfer data, such as batch recipes from a SQL database to an InTouch application. It also facilitates the transfer of run-time data, alarm status or historical data from InTouch to the SQL database. For example, after a machine cycle is completed, a company may need to save several sets of data, each for a different application. SQL databases provide the ability for information to be transferred between one or more third-party applications easily. SQL Access Manager allows this data to be accessed and displayed in any InTouch application
[ pdf ] MySQL as a linked server in MS SQL Server
This document describes how to link a Microsoft SQL Server 7.0/2000 (MS SQL) and a MySQL 4.x server. After linking, the linked MySQL server behaves as if it is a local SQL Server. Having linked the two servers, examples of some things you could do are automatically synchronizing each Update/Insert/Delete on the MS SQL database immediately in the tables on the linked MySQL server or write a SQL query that uses tables and data on both servers simultaneously.
[ pdf ] Welding Fabrication Standards
Topic: Welding Systems
In this framework The Italian institute of welding (Istituto Italiano della Saldatura - IIS), has developedĽ the following educational tools for the classroom instruction: − slide presentation through computer projector, to be used by teachers during the training courses; − books (electronic and/or paper format), to be used by participants; − exercise questions, to be used during classroom instruction. This book is therefore meant to provide direct and clear information on European standards relevant to welding fabrication, as these are subject to continuous updating; therefore knowledge of requirements of the standards is to be considered basic knowledge for welding co-ordinators and inspection personnel. Moreover this book has been recently integrated taking into consideration guidelines produced by EWF for the application of ISO 3834 requirements, produced after several years of experience of its members in technical assistance on the field of welding fabrication, education and training of welding and NDT personnel and in certification of welded products manufacturers.
