I have a project where I need to establish a SIL-3 rated communication between the Charm Smart Logic Solvers (new scope we are providing) and the Old and (SLS 1508) - existing.
a SIL-2 or possibly 3 rated shutdown function is shared between these two system.
The New System will have it's own ProPlus and the Old has it's own. Is there a possibility of SISNET communication between these system? Does having separate ProPlus impacts the system? what would be the recommended architecture?
