SOFTWARE MODELING
|
Example of Software Modeling
1. Situation:
- PLC and HMI software can and should be modeled.
- During a project for Process Manufacture, all system configurations for process conditions/permutations were developed, and the PLC systems engineers were required to evaluate all process conditions using software tools to provide feedback and allow for off-line simulation. Approximately 30 different configurations were presented.
- PHAs were also required to meet the Management of Change (MOCs) Policy.
3. Cost for Model Development:
- Cost to develop the Model and Software PLC Testing was about $35,000.
4. Client Benefits:
- System diagrams were required to facilitate PHAs
- Less down time
- Less possibility of system failure
- Less field cost for contractors and engineers
- Quicker process start ups
- Compliance with NFPA and OSHA for covered processes
