Sensor status
Function blocking
The block signal is checked in the beginning of each program cycle. The blocking signal is received
from the blocking matrix in the function's dedicated input. If the blocking signal is not activated when
the pick-up element activates, a TRIP signal is generated.
If the blocking signal is active when the pick-up element activates, a BLOCKED signal is generated and
the function does not process the situation further.
The variables the user can set are binary signals from the system. The blocking signal needs to reach
the device minimum of 5 ms before the set operating delay has passed in order for the blocking to
activate in time.
Events and registers
The arc fault protection function (abbreviated "ARC" in event block names) generates events and
registers from the status changes in the events listed below. The user can select which event
messages are stored in the main event buffer: ON, OFF, or both. The events triggered by the function
are recorded with a time stamp.
The function's outputs can be used for direct I/O controlling and user logic programming. The function
also provides a resettable cumulative counter for the events.
