PLC Based Hardware

RHINO PLC based hardware

The advantage of PLC base hardware is discussed here. The existing power-lines form the communication media for the RHINO hardware.

The RHINO based devices are of two main types:

  1. The Master Node often referred as the Segment Builder (SB). This device is the main controller of the PL-Network. It is responsible for initiating communication to the slave nodes (see 2 below) plus manage dynamic routing paths and optimize communication with the slaves. There exist both single phase masters as well as 3 phase masters communicating on all phases of a 3-phase grid simultaneously.
  2. Slave Node(s). Each Master node can manage up to 1024 Slave Nodes on the same PL-Network. A Slave Node is connected to one or more devices for controlling and/or data collection/alarming.

Our hardware development team is currently implementing a whole new line of hardware for Control2Net, named by shortcut WELC. As discussed here, PLC communication will be available for this hardware in late 2013 as an optional plug&play interface-card. This will add even more flexibility to the WELC hardware, which will be capale of communicating over conventional ethernet (building LAN for example), wirless WiFi or over the existing power lines (PLC). Even with all 3 options enabled the WELC hardware will be more cost effective than seen before in the market. 

This new hardware from Rational Network, will add to the current flora of PLC-based hardware from our hardware partner in the Netherlands, described below, which we offer today to our customers.

Three Phase Segment Builder

The Segment Builder (SB) is a powerful 3-phase master node. The Firmware of the SB is different for different applications. For example there exist a version specially intended for data logging like Automatic Meter Reading (AMR), another for Street Lighting, etc. Each variant is discussed in more details in each Business Solution section (see links on left site of this web page).

Key Features:

  • Three Phase PLC
  • Can manage up to 1024 slave controllers on the Power Line.
  • Six IOs configurable as Digital I/O or Pulse Input.
  • Two IOs selectable by plug-in as either Digital IO, Pulse Input, 4-20mA Input, Temperature Input or 0-10V IOs.
  • Powerful LED system for easy installation and on-site debugging.
  • RS485 connectivity for daisy chaining multiple Segment Builders.
  • Built in Scheduler.
  • Mirror logging for slave loggers. SB can poll up to 1024 slaves for data, such that all logged data on the PL Network exist in the SB for retrieval from a central server.
  • Enough memory to hold up to 8000 log entries for each SB channel and every mirrored slave.
  • Automatic routing that selects the optimum communication path with each logger depending on instant PL disturbance and attenuation.
  • Easy to configure.

Key Benefits

  • No new wires as the existing power lines are used for communication.
  • A device network is formed in the building or street as soon as you plug in a SB.
  • One SB installed in a building or street, can serve multiple buildings/streets over the 3 phase grid, within the same transformer.

DIN Logger

The 4 channel DIN Logger is intended for logging data from meters (energy, gas, temperature, etc.) plus controlling relays or analog outputs. In fact it is a mini-version of the segment builder.

 

  • Two IOs configurable as Digital I/O or Pulse Input.
  • Two IOs selectable by plug-in as either Digital IO, Pulse Input, 4-20mA Input, Temperature Input or 0-10V IOs.
  • Powerful LED system for easy installation and on-site debugging.
  • Built in Scheduler.
  • Enough memory to hold up to 8000 log entries.
  • Can be used as a standalone logger (without any master).

 

Key Benefits

  • No new wires as the existing power lines are used for communication.
  • Easy to configure.
  • Cost effective.

If ordered with a temperature plug-in, two digital temperature sensors are provided with the logger (or SB). Please specify ordering codes properly. Both loggers and SB are housed in a standard DIN Rail housing made of plastic. The RJ-11-6 connector on both the loggers and SBs is for RS232 communication. Only RD and TD lines have to be connected. Both loggers and SBs are supplied with a PLC-LED, that gives indication of traffic between a SB and a logger, where green light indicates that the hardware unit is sending data but red light that the unit is receiving data on the PL.
