Full Description

There are a number of specific features available with distributed control systems, such as operator interface devices, preventative maintenance features, security levels, windowing, database software, options, backup options. etc. Therefore, it is important to take an adequate amount time to review what goals should be achieved with the new distributed control system. Goals should include modifications to existing plant control schemes which have failed to master the proper control of existing processes, or which require improvement to meet control expectations. Repetitious work, such as daily reports, chemical inventory and usage, logging equipment run times, and general calculations should be considered as part of the DCS responsibility, so that these manhours can be spent on items of higher priority. Manually entered lab data could also take advantage of the systems trending and calculating abilities. Ideas should be discussed with all plant personnel involved, so that all possible thoughts, suggestions, and time-saving concepts can be implemented into the system. Outside help is often essential from equipment vendors and consultants in helping to establish goals and in applying these goals to the available equipment and software on the market. Regardless of the type of system chose, the benefits of a distributed control system will not be utilized to the full extent unless clear and concise goals are established and implemented early in the system selection process.
