— Virtual I/O
Preface
By ThyVisor 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 defined 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
• Significantly 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 significant 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 significantly long in correspondence of the power source.
• Circuit breaker commands
• Selection of setting profiles
• Remote trip
• Include I / O in the programmable logic (PLC)
• etc. ..
