Requirements and Analysis Needed in Implementing

Control SystemsTobey Strauch

Navarro Systems

Traditional software systems have requirements definitions and planning with a system life cycle implementation.

So should industrial controls.

Motivation

6 stages◦ Planning◦ Analysis◦ Design◦ Construction◦ Test◦ Rollout

(Morris, 2013).

System Life Cycle

Stages:

Resource: (Ponce, 2013)

Due Diligence with Requirements◦ System purpose◦ System life cycle◦ System fault criteria◦ System interface criteria◦ Hardware criteria◦ Deliverables◦ Time frame◦ Training

Alleviate Long Test Cycles

Everyone should learn from the chemical and pharmaceutical industry ◦ Don’t accept equipment that does not meet

prescribed requirements◦ Make sure your requirements are in place before

allowing design functions to start◦ Decrease maintenance and poor start ups◦ Make fault predictions early on
