SICAM PAS (Power Automation System)
Substation control system: The range of possible configurations spans from integrated standalone systems
(SICAM PAS and M&C with SICAM PAS CC on one computer) to separate hardware for SICAM PAS and

with basic and optional packages. SICAM PAS is a purely distributed system: the process interface is imple-
mented by the use of bay units / remote terminal units.
