Integrated DCS and SIS or Isolated Systems
|| Found it worth Sharing ||
ISA- InTech Article
My Conclusion-
Which systems are better?
The original separate Safety
Instrumented Systems where the logic solver is totally different or the
integrated version, where the same system has two different kinds of
controllers/logic solvers-one type for the BPCS and another type for the SIS?
Note that the integrated SIS DCS does not imply that it is one
common system, it is just integrated for ease of use an convenience.
Thus the configuration software may
have different types of logic blocks, some meant exclusively for use in safety
functions, whereas other can be used in the normal BPCS functions. If the logic
solvers/ controllers need to communicate with other logic solvers, then it has
to be over a "safety bus".

I for Instrumentation
The purpose of an instrumentation engineer is to Conceptualise, Design, Detail, Maintain and Traouble shoot control system for its client/ industry. Changed mindset and government’s compliance put efforts to make safety as first priority against profits and production.
