Process Bus Definition
> Process bus is the combination of all interfaces
between the process and the SPACS communicating
data and information that can be shared between the
PIU and the SPACS functions.
> The process can be divided in three major parts: > The power process
> The auxiliary process
> Building/Substation process

Reduced Installation Costs
• Reduced costs due to the replacement of hundreds or
even thousands control cables with a limited number of
fiber optic cables
• Reduced costs due to the replacement of the wiring of
hundreds of copper wires to the panels’ terminal blocks
and then from the terminal blocks to the relay terminals
with the plugging in of a few pairs of fiber cables
• Reduced costs due to the requirements for testing of all
hard wired interfaces versus the testing of the GOOSE
messages based on advanced software tools
