Using Serial/IP
  • The substation management application is reconfigured to use the virtual COM ports provided by the Serial/IP Redirector.
  • When the application opens a virtual COM port, Serial/IP initiates a network connection to a specific device on a serial server.
Key Results
  • The existing application is used unchanged.
  • The application reaches field equipment at any substation on the network, potentially scaling to thousands of devices.
  • Serial servers at substations can be sourced from any manufacturer that uses public protocols.
