DREW 229 – Teaching Computer Laboratory/Classroom
Drew Hall room 229 is the College’s Teaching Computer Laboratory/Classroom. The room includes 30 computers dedicated to student use and 1 computer dedicated to the instructor. It is used by both, the Department of Engineering and the Department of Engineering Technology to teach courses/labs. In addition, the room includes a ceiling mounted projector connected to the instructor's computer, a Smartboard and an Elmo document camera that give the instructor a wide range of state-of-art equipment to present class material. Student work can be printed using a high output laser printer or a high-speed, E-size, graphics printer. All computers carry a wide range of software that is available for student/instructor use.
DREW 328 – Programmable Logic Controller Laboratory
The Programmable Logic Controller (PLC) Laboratory is used to teach INST304 (Lec. 3 Lab. 3 Cr. 1), which is a required lecture and lab course for B.S. Engineering Technology students in the Instrumentation concentration and is an elective for Electronics students. It is also used to teach ENGR 475 (Lab. 3 Cr. 1) which complements the ENGR 430 – Systems and Control course (Lec. 3 Cr. 3).
The material covered in INST304 covers types of PLCs, PLC hardware components, ladder logic programming, programming of timers and counters, forcing inputs and outputs, comparison instructions, and PLC installation practices and troubleshooting.
Drew 328 houses 7 stations. Each station is equipped with an Allen-Bradley SLC 500, which is a popular PLC found in industry. Each PLC is mounted on a standard Hubbell rack and has a PC interfaced to the PLC to develop and test PLC programs. All 7 stations use RSLogix 500 software to develop and test PLC programs, and the LogixPro PLC simulator to create an even larger variety of PLC programs.
Four of the PLC stations have the following configuration:
- SLC 5/03 CPU module in a four-slot PLC chassis
- 8 toggle switches for discrete inputs
- 8 LEDs for discrete outputs
- 1 Normally Open pushbutton
- 1 Normally Closed pushbutton
- 1 AC input module
- 1 Relay output module, using 24V as an output voltage
- 1 Thermocouple module used to measure temperature
One of these four stations is also connected to the Feedback 34-100 Conveyor system and additional modules, such as analog I/O modules, are available to create other PLC configurations.
Three of the PLC stations have the following configuration:
- SLC 5/04 CPU module in a seven-slot PLC chassis
- 4 toggle switches for discrete inputs
- 4 LEDs for discrete outputs
- 1 AC input module
