How to Select a Process Control System for a Hybrid Application This paper has described the key attributes and differentiators between classic PLC and DCS systems. This same information can be used to define the key requirements for a process control system that would be ideally suited for hybrid applications, such as those in the pharmaceutical, fine chemicals, and food & beverage industries. Controller – Can execute fast scan logic (10- 20 msec), such as that required for motor control, and slow scan logic (100 - 500 msec), such as required for analog control, simultaneously in a single controller Engineering Configuration Languages – Provides ladder logic, function block diagram, and a powerful programming language for creation of custom logic from scratch Flexible Modular Redundancy – Offers the option of tailoring the level of system redundancy to deliver the required system availability by balancing up-front cost versus the cost of unplanned downtime Modular Batch from Simple to Complex – Provides modular batch capability to cost-effectively address the continuum of simple to complex batch applications Alarm Management – Offers power alarm management tools to help operators respond effectively to plant upset conditions System Diagnostics and Asset Management – Provides both a rich set of built-in system diagnostics, as well as asset management of all critical assets in the plant (transmitters, valve positioners, motors, drives, MCCs, heat exchangers, etc.) Scalable Platform – Hardware, software, and licensing supports smooth and economical scale up from small all-in-one systems (10s of I/O) up to large client/server systems (10,000s of I/O) [email protected] 079 6616 8867 / 8875
