Command Processing
A control command function is integrated in the 7SC805 device to coordinate the the switching operations in
the substation.
Control commands can originate from four command sources:
• Operation using the Web Monitor
• Operation using DIGSI
• Remote control via a substation control system (e.g. SICAM)
• Automatic functions (e.g. via binary input)
Switchgear with single and multiple busbars are supported. The number of switchgear devices to be controlled
is limited only by the number of available binary inputs and outputs. Interlocking checks ensure high security
against maloperation, and a multitude of switchgear types and operating modes are available.
