Process Control and Automation

Process control and automation (PC&A) systems must provide safe and effective control and monitoring of plant. The targets are to improve productivity and quality. TARA TARH??has extensive knowledge of automation systems in a range of sectors including power generation, ferrous and non-ferrous metals, and Mineral processing.

The primary concern of an automation system is that the requirements and suitability of programmable logic controller (PLC) and distributed control systems (DCS) for basic automation suit the manufacturing process. The basic automation system should also be suitably integrated with the supervisory control of production (Level 2) and manufacturing execution systems (Level 3). TARA TARH, through many years of experience, understands the various types of processes, whether discrete, batch or continuous and the dynamic variables associated with them. Requirements for proper specification, operation and maintenance (O&M) documentation and quality assurance are of particular importance; these are essential to ensure a satisfactory solution in the long term.
