An example of an interface between the exSILentia tool and a third party tool is an automatic interpretation of the exSILentia export file to populate a logic solver programming tool with the Safety Instrumented Functions configurations as specified in the SILver tool. This drastically reduces the amount of engineering time required and reduces the likelihood of errors in the interpretation of the SILver output and conversion to the logic solver application program. Currently the following third party interfaces are available: l Import from PHA-Pro® l Import from PHAWorks® For information on any of the third party interfaces listed, please contact the exSILentia Team (exSILentia@exida.com). © exida.com L.L.C. exSILentia® User Guide Page 11 of 168 Chapter 1 Installation The exSILentia installation package consists of l exSILentia CD l exSILentia USB key l exSILentia User Guide To install exSILentia on your computer place the exSILentia CD in your CD-ROM drive. exSILentia setup will take you through the installation process.
