Protection devices
All devices with a protective function and no control display.
Reorganizing
Frequent addition and deletion of objects creates memory areas that can no longer be used. By cleaning up
projects, you can release these memory areas. However, a clean up also reassigns the VD addresses. As a
consequence, all SIPROTEC 4 devices need to be reinitialized.

SCADA Interface

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
SICAM PAS CC to distributed systems with multiple SICAM Station Units. The software is a modular system
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.
SICAM Station Unit
The SICAM Station Unit with its special hardware (no fan, no rotating parts) and its Windows XP Embedded
operating system is the basis for SICAM PAS.
