FUNCTION CHARACTERISTICS
Virtual I/O
Preface
By ThySetter and ThyVisor software tools the type of operation and links between outputs (Virtual
Output - VOUT1 ... 16) and virtual inputs (Virtual Inputs - VIN1 ... VIN32) may be defi ned using RPC or
IEC 61850 communication protocols over Ethernet network.
The system allows:
[1]
Availability of sixteen inputs and thirty-two outputs independently programmable by the user
Simplify wiring using one channel as the Ethernet
Eliminate the need to install communication devices and / or external conversion
Signifi cantly reduce costs
Dynamically change from sw connections and associated functions.
Applications
With Pro-N and Pro-XX relay the virtual I / O can be usefully employed for:
Transmit information between protections installed in signifi cant distance where the traditional
connections are critical in terms of reliability.
Making OR logic for opening control of multiple DDI (simultaneous control of all DDI operated by
each SPI) in cases of multiple interface protections (Smart Grids)
Achieve accelerated logic discrimination in which some protection elements can be blocked by the
activation of the downstream protection start; this allows to reduce the clearing time that, in time
logic systems require trip time signifi cantly long in correspondence of the power source.
Circuit breaker commands
Selection of setting profi les
Remote trip
Include I / O in the programmable logic (PLC)
etc. ..
