Direct Remote Trip and Transmission of Binary Information

2.13.1

Description

7SD80 allows up to 16 information items of any type to be transmitted from one device to another. Like the
protection signals, these are transmitted with high priority.
The information items can be fed into the device via binary inputs. The integrated user-defined CFC logic allows
the signals to be linked logically with one another or with other information items of the device's protection and
monitoring functions. Also an internal indication can be assigned via CFC to a transmission input and transmit-
ted to the remote end(s).
The up to 16 binary inputs „>Rem. Signal 1" to „>Rem.Signal16" must be routed and are available ac-
cordingly at „Rem.Sig 1 Rx" etc. on the receiving side.
When allocating the binary inputs using DIGSI, you can give the information items to be transmitted individual
names.
The device indications, e.g. „Master Login", can be used to monitor the signals of the sending devices.
If a fault in the protection interface communication is detected, the time Td ResetRemote (address 4512) for
resetting the remote signals is started. If the communication is interrupted, an incoming reception signal will
maintain its status for that time.
No other settings are required for the transmission of binary information. The device sends the injected infor-
mation to the device at the end of the protected object.
