Control System Scope and Job Activity in ...

Objective of this topic is to introduce about the role / job activity of instrumentation & control in various EPC / EPCM (Engineering, Procurement, Construction & Maintenance) groups / designing companies. These EPC groups designs the process plants such as Refineries, Power Plants, Steel Plants & Sugar Mills etc. The EPC companies have various Departments (Electrical, Mechanical, Instrumentation and Control, Procurement & Civil). All of these department works together for a pro-ject to be executed. INSTRUCALC 6.2 is the latest version of the Instrucalc software that can be used for accurate sizing of more than 50 different instruments. The latest standard “IEC 1131-3″ has been tried to merge plc programming languages under one international standard. We now have PLCs that are programmable in function block diagrams, instruction lists, C and structured text all at the same time. A distributed control system integrates the PLCs and process controllers of a process line into a coordinated and interactive system. It enables us to manage the process as a complete system, with control over the inter relationship of the various subsystems. INtools provides a single source of plant information that can be easily accessed and updated and ensures consistency across the different instrument tasks and deliverables.
