Luciol Hardware Overview

To date Luciol is a case containing a CPU module alone or with:
  • a Mother board with:
    • a set of I/O modules
    • a modem module

Luciol is built around its CPU board based on the aJ100 processor of aJile Systems. Thanks to this CPU, you can code in real-time Java your own applications and embed them in Luciol.

The CPU board includes the aJ100 processor @ 70 MHz with 1Mb of RAM and 4 Mb of FLASH, the 48Vdc-125Vdc power supply and the communication ports: one off RJ45 for a 10Mb/s Ethernet port, one off RS232 port and one off RS232/485 port.

The RS232/485 port is a RS232 or RS485 port by a jumper configuration.

The CPU board for the extension Luciol box has no aJ100 processor, Ethernet controller, RSxxx ports and memory. The Ethernet RJ45 port is used as an extension port for the daisy chain between all the Luciol boxes.

The Mother board in Luciol is an active backplane: it is used to interface I/O & communication modules to the CPU board.

The Mother board has a micro-controller. This micro-controller can time-stamp the data from its local I/O modules and store & forward data in case of avalanche. The Mother module of the main Luciol is in charge of the time synchronisation.

Communication between two Mother boards is made with a multi-master protocol communicating at 125 kb/s over a 2 wire RS485 link.

Communication between Mother module controller and CPU processor uses an 8 bit data bus and is event driven. 		The I/O Modules connected to the Mother module are to date:
  • 8 Digital Input module
  • 8 Digital Output module
  • 4 Analogue Input module
  • 4 Analogue Output module
These modules may be installed either Luciol standard or extension boxes.

All the I/O modules have a micro-controller on board.

The Mother module controls communication with I/O modules over a synchronous serial link at 125 kb/s. However, data are instantly fetched from I/O modules over a bidirectionnal 8 bit parallel link.

Mother controller allows to access the local data of all I/O modules, including those in extension Luciols via their respective Mother modules. The CPU can then retreive all the identification information regarding the I/O modules plugged in Luciol boxes.

The Modem module is plugged in a slot of the Mother board as the I/O modules. The Modem port is directly interfaced to the CPU and replaces its RS232 port.

At start-up, Luciol main CPU checks than the physical location of I/O modules locations are consistent with the configuration made by the User: in case of error, the Luciol applications will not start.

At any time, using a web browser the User can check the content of every module connected to the Luciol main box: type, location, firmware version, ...

Luciol hardware has been tested to withstand the harsh environment of electrical substations i.e. these standards.
