Unit shutdown design for a batch control application

Shashank Paithankar, Honeywell Automation India, LTd. Exception handling has always been critical to batch operations. Paithankar provided some examples. Conventional approach for exception handling includes a hold hanler and an abort handler of the Unit Phase. Excepton handling is a Major Effort-- 40-50% of Implementation and Testing effort. This can be a redundant programming effort, use excessive memory, and generally eat the project's lunch. The idea is to address Exception Handling in an S88 compliant way. Paithankar went through a Honeywell implementation for a pharma plant in Puerto Rico.
