RECOMMENDATIONS……
•LEARN & PRACTICE
• -AUTOCAD
• -HMI SOFTWARE LIKE INTELUSION
•READ INSTRUMENATAION HAND BOOK
BY LIPTAK
•EACH STUDENT TO OWN ONE MC KIT &
DEVELOP SKILLS IN EMBEDDED SYSTEM
•SPEND ONE HOUR IN INTERNET DAILY &
RECORD YOUR FINDINGS
•REGISTER IN PLANT WEB UNIVERSITY
IN EMERSON WEBSITE & GET
CERTIFICATE (FREE)
• EACH STUDENT TO GIVE LECTURE
ON ADVANCED TOPIC PERIODICALLY
