The following use cases give an introduction to the wide variety of potential uses of the XPL Rail device family.

Use Case: Underfloor Heating

Simple application with powerline controlled underfloor heating valves

  • up to 6 heating circuits are controlled from one XPL Rail 4M – IO600
  • upper application with manual control
  • lower application with programable logic controller
  • used device: XPL Rail 4M – IO600

Use Case: Partitioned RS-485 Busses

Example with distributed Modbus devices in the same building

  • powerline is the linking element between multiple RS-485 bus segments
  • transparent RS-485 data transfer (not necessarily Modbus)
  • mangement of several device groups with different protocols
  • connection of bus segments with different baud rates
  • used device: XPL Rail 4M – 48500

Use Case: Light Control

Stand alone system for light control without a central unit

  • independent control of up to 6 lights with up to 6 switches
  • simple automation features like automatic switch off or flexible on time
  • useable for switches or pushbuttons
  • used device: XPL Rail 4M – IO600

Use Case: Remote Control

Complete Home Control via Powerline

  • fan and light control depending on incoming sensor values
  • meter reading
  • enable/disable of EV charging function
  • all functions are PC controlled via JSON object communication
  • used devices: XPL Rail 4M – IO600, XPL Rail 4M – 48500

See AN5 – Using serial XPL Rail devices with a virtual COM Port (Rev. 1) for more information how to setup such a scenario.

Use Case: Entrance Illumination

Computer controlled lighting application

  • control of dimmable lights
  • variable ramp up and ramp down functions
  • sensor input for ambient light measurement
  • user interface with switches or pushbuttons
  • power saving mode with 3 relays in XPL Rail 4M – R3A30
  • used devices: XPL Rail 4M – R3A30, XPL Rail 4M – IO600

Use Case: Modbus RTU Access over Powerline

PC connection to a Modbus RTU system via powerline

  • on PC side no RS-485 interface required
  • communication via virtual COM port driver
  • used device: XPL Rail 4M – 48500

See AN5 – Using serial XPL Rail devices with a virtual COM Port (Rev. 1) for more information how to setup such a scenario.

Use Case: Remote RS-485 Monitoring

Simple monitoring function of a RS-485 communication system

  • on PC side no RS-485 interface required
  • communication via virtual COM port driver
  • simple implementation of a data logging function on PC side
  • used device: XPL Rail 4M – 48500

See AN5 – Using serial XPL Rail devices with a virtual COM Port (Rev. 1) for more information how to setup such a scenario.
