This UFC supersedes UFC 3-410-02, dated 5 2012. 2 UFC 3-410-02 18 July 2018 Change 2, 12 April 2021 FOREWORD The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States is also governed by Status of Forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA.) Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable. UFC are living documents and will be periodically reviewed, updated, and made available to users as part of the Services’ responsibility for providing technical criteria for military construction. Headquarters, U.S. Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) are responsible for administration of the UFC system. Defense agencies should contact the preparing service for document interpretation and improvements. Technical content of UFC is the responsibility of the cognizant DoD working group. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: Criteria Change Request. The form is also accessible from the Internet sites listed below. UFC are effective upon issuance and are distributed only in electronic media from the following source: • Whole Building Design Guide web site http://dod.wbdg.org/. Refer to UFC 1-200-01, DoD Building Code (General Building Requirements), for implementation of new issuances on projects.

The guidance is particularly detailed due to the complex and definitive requirements required for the design of a digital control system and for the procurement of an Open system that supports integration into a multi-vendor system. Reasons for Document: Initial version of this UFC covered LNS-Based LonWorks only. Extensive revisions were required to accommodate BACnet and the Niagara Framework. Impact: There are negligible cost impacts; however, these benefits should be realized: • The ability to procure systems competitively that can be integrated into a single supervisory system rather than requiring the procurement of several supervisory systems. • Competitive procurement of control systems will result in cost savings. Describe the impact. This should describe impact on design cost, initial cost, energy savings, or life cycle costs.

PLC HISTORY The early history of the PLC (Programmable Logic Controller) goes back to the 1960’s when control systems were still handled using relay control. During this time the control rooms consisted of sev- eral walls containing many relays, terminal blocks and mass of wires. In 1968 Bill Stone, who was part of a group of engineers at the Hydramatic Division of General Mo- tors Corporation, presented a paper at the Westinghouse Conference outlining their problems with reliability and documentation for the machines at this plant. He also presented a design criteria de- veloped by the GM engineers for a “standard machine controller”, to eliminate costly scrapping of assembly-line relays. These specifications along with a proposal request to build a prototype were given to four control builders: • Allen-Bradley, by way of Michigan-based Information Instruments, Inc.
