Chemical Processing - February 2008 - (Page 33) restart, stop, abort and reset. In addition, S-88 defines various states of a process (e.g., running, holding, pausing, aborting, etc.). This adds another dimension to the applicability and, therefore, configuration of a particular alarm — namely, the enabling of an alarm specific not only to a batch process step or phase but also to the process state. Managing states and transitions between states is a very important batch automation topic in that, for many processes, the amount of logic associated with these aspects of a process greatly exceeds that for the normal running of the process. Vendor software off-the-shelf functionality Most automation vendors’ roots are in the continuous process industries; they only recently have been addressing the unique needs of batch processes, including regulatory requirements for validation (such as electronic records and signatures). Keep this in mind when starting a new automation project. The documented system functional requirements that typically are pursued near the beginning of a project may influence vendor selection or the need for customization of the system. Often when a project engineering team has assumed that a vendor’s automation system will provide all the alarm (and other process control) functionality that will be needed, the end result has frustrated both automation engineers and users when it was discovered too late in the project timeline that the system didn’t provide all the desired functionality. Other project engineering teams have recognized alarm management limitations in commercial off-theshelf software systems and, therefore, sometimes have chosen to interface third-party products (alarm loggers, paging systems, expert systems, etc.) with their core DCS/PLC/historian automation systems. Other project teams have worked with automation vendors to customize the suppliers’ standard product offerings. www.chemicalprocessing.com http://www.buschusa.com http://www.buschusa.com http://www.chemicalprocessing.com
