User Defined Functions
• Freely programmable linking of internal and external signals in order to implement user-defined logic func-
tions.
• All standard logic functions (AND, OR, NOT, EXCLUSIVE-OR, etc.)
• Time delays and limit value interrogations
• Processing of measured values, including zero suppression, adding a knee curve for a transducer input, and
live-zero monitoring.
Breaker Control
• Switching devices can be opened and closed manually using control keys, programmable function keys, via
port B (e.g. of SICAM or LSA), or via the user interface (using a personal computer and the DIGSI operating
software)
• Feedback of switching states via the switch auxiliary contacts
• Plausibility monitoring of the circuit breaker position and check of interlocking conditions.
