Protective Elements
•
The user can assign module outputs or signals to signals of the Sig-Trans module (1).
•
These signals are transmitted (2) via the protection communication interface (3) to the remote device.
•
The Sig-Trans module of the remote device receives (4) the signals and triggers the respectively assigned
digital inputs.
These digital inputs can be used to enable or disable functions, or to switch the parameter set, or assign these
signals to protection and / or control modules.
If the protection communication should fail the signal transfer is blocked. It is possible to configure a fallback rule
for each of the 16 signals, so that it keeps a valid value if communication is lost.
Available Setting Values for Rx.Signal1.Fail-safe, …, Rx.Signal16.Fail-safe Default Value
•
Fixed 0
Fallback of received status to 0 (inactive).
•
Fixed 1
Fallback of received status to 1 (active)
•
Captured (Init. 0)
The last valid received status is kept. If there has not been any valid received
value yet, the status is initialized to 0 (inactive).
•
