Summary of the overall system integration process

The major safety instrumented system integration services provided with the SIS logic solver consisted of a number of activities including. 

This consists of the installation of the SIS logic solver into cabinets with the appropriate termination panels for connecting the process signals to the logic solver I/O modules. Power supplies and power distribution for the logic solver and field devices are also normally included.

The SIS logic solver safety certified application software development package is used to configure the SIS logic solver I/O and communication hardware. The application software for each safety instrumented function as well as non-critical application software are also implemented and tested. 

Many customers conduct a factory acceptance test to check the correct operation of the hardware and application software before it is shipped to the plant. The hardware and application software are thoroughly tested by the customer s engineers and other operating personnel.
