Luciol Overview

Luciol is a “communication” brick in a process control system.

For the end-user, let’s put it in the mini-RTU category.

However, for a System Integrator, Luciol is entirely programmed in C and Java rather than with IEC61131 languages -i.e. Ladder, SFC, IL, ... - like a programmable controller. Note: Luciol has a tool to convert your PLC programs from  their IL version to Java.

Physically, Luciol is a set of hardware modules and software applications.

Luciol is organised around the CPU module, the CPU only runs the high-level data processings. The CPU is also in charge of RS232/485 & Ethernet management.

The Mother module is the interface between the I/O modules and the CPU and is in charge of the time stamping and synchronization. The Mother module also deals with the interface between main and extension Luciols.

I/O modules address data acquisition and low level signal processing: filtering, debouncing, ... The I/O modules have a micro-controller for this purpose.

Available modules are: an 8 off Digital Inputs, an 8 off Digital Outputs, a 4 off Analogue Inputs and a 4 off Analogue Outputs.

Other modules are:
  • Modem module for connection to a PSTN
  • RS232/485 module for serial port in addition to the CPU ports (under design)
Luciol has two different types: “main” and “extension”. From a mechanical point of view, these two types use the same case, blank plates, ...

The “main” type is a Luciol case with a CPU board. Note: “standard” type is a main Luciol with 4 off I/O modules.

The “extension” type is a Luciol case with a simplified CPU board. simplified stands for: no CPU and no RSxxx ports as the “extension” boxes are dedicated to additional IO board for one “main” Luciol.

Up to 15 extension Luciols may be chained to one main Luciol.

Luciol can be either configured using a simple web browser or configuration tool as a plug-in of the powerful Eclipse IDE.

When developing applications with Luciol, you may either use your preferred Java IDE or Eclipse IDE. You will then interface your PC to your Luciol with a JTag interface to download your software on the CPU and debug your code.
Luciol Typical Applications

Luciol may be used as a protocol converter of industrial protocols. For this application, only the CPU and the Luciol case are required.

Protocol Converter Application

Luciol may also be used as a protocol sniffer either over a RS485 link or Ethernet. Luciol may then display the industrial protocol data frame exchanged between the different field devices.

An engineer may use a Luciol as a gateway to access IEDs from his desktop PC. The gateway can be either transparent i.e. "pass-thru" or convert protocols. Several Luciol may even be installed to the different locations in order to provide a full tunnelling system.

Monitoring Application

In a control system, Luciol may be used to provide complementary Digital and Analogue I/Os in addition to those available from field devices.

During refurbishment of protection & control systems, Luciol may be used as an interface between a digital control system and conventional field devices.

RTU Application

Luciol may also be used in a test bench for validation of a Control. Using a web server, the user can trigger and visualize I/Os. Adding an injection box, it could now validate the complete Protection & Control system.

Luciol is compact and versatile, the applications it could fit in are not yet all identified.
