The Use of Direct Digital Controls in Utility Systems at Army Installations: A Review of Current Technologies.
Abstract
This study identified and investigated four major types of microprocessor based control hardware to determine their possible application to Army utilities: (1) Programmable Logic Controllers (PLCs); (2) Single Loop Digital Controllers (SLDCs); (3) Commercial Direct Digital Controls; and (4) STD and VME bus based controls. Variables such as cost, ease of use, programming requirements, and maintenance requirements were evaluated. Commercial DDC, SLDC, and PLC were found to have features most useful to Army utilities. The study recommended further research in the form of demonstration projects to develop implementation strategies for this technology.
