Presenter: Ron Auvil Slide 2 Presentation Outline: Introductions and Technological Advances Networking And Collaboration Network Overview Network Software Servers Wireless Networking Diagnostic and Troubleshooting Tools Troubleshooting Scenarios (2) Slide 3 Graduate of West Side Institute of Technology in Cleveland Ohio In HVAC Industry over 37 years Licensed 3 rd Class Stationary Engineer 33 Years Part and Full Time Training Experience, including 16 yrs on Faculty of Community College Author, HVAC Control Systems, HVAC and Refrigeration Systems, IT for HVAC Technicians American Technical Publishers. Owner, High Performance Mechanical Training Technical Contributor Fluke Corporation. Currently Senior Technician/Trainer with Johnson Controls, Charlotte, NC 17 Years with JCI as Lead Instructor HVAC and Controls Slide 4 Mechanical and control systems are becoming increasingly more sophisticated. As a matter of fact, the rate of change technologically is increasing. Mechanical systems changes include refrigerants, motor designs, variable speed drives, magnetic bearings, etc. Control systems changes include advanced PC/server applications, impact of web and web enabled devices. Combined with lack of training the result is Products introduced with no one able to install or service them? i.e. 750 page server software installation instructions? Service both NEW and OLD challenges Slide 5 Today, Most Commercial HVAC Control Systems are put on a customer computer network. What is a Network? A network is a system of nodes and other devices that are joined using connecting media that provides the means of data communication between the nodes. (ITH P#1) Facility IT and HVAC Technician Collaboration. (ITH P#4) Understanding the facility IT Staff Role and the HVAC Technician Role. Knowledge of terminology, use of tools and troubleshooting are paramount. Slide 6 So, how does this impact our classrooms and what can we do about it? Programs, technology, equipment quickly go out of date. Instructors easily caught behind an increasingly steep technological curve. Introduction of basic Information Technology (IT) training into HVAC programs, especially Controls training classes. Equipment and computer updates, 3 year cycles at most. Materials, books, training aids, etc. up to date Big Task! Slide 7 Network Types: LAN/WAN ( ITH P#5) Network Topologies; Star, Bus, Daisy Chain, etc. Data Packets, Bandwidth and Throughput. MAC Addressing; NIC Cards Media/Cable UTP; Cat 5, 5e, 6. (ITH P#11) Switches, Routers. IP Addressing: ( ITH P#4) Slide 8 Switches, Routers. IP Addressing: ( ITH P#18) Slide 9 Web Based Supervisory Controllers ( ITH P#21) Slide 10 Slide 11 Client Computers Operating System: ( ITH P#27) Slide 12 Other Software: Java, Windows Dependencies, Browsers; System Security, Firewalls Software Troubleshooting Skills Slide 13 Server Functions and Sizes (ITH P#36) Functions: Passwords, Controller Tools, Long Term Data Storage, Email, Alarms, Printer, Smartphone/Tablet interface, SQL.
