SCADA plugin
SCADA plugin for JMP (demo)
... - JMP nodes must be running on all machines involved, i.e. both "polling" and "polled" machines. - Machines communicate over custom protocol on top of Java RMI with encryption. - The "field-level" machine gets the data from PLCs via Modbus. Any custom protocol can be added via new data import class. - SCADA graphical output and polling parameters are set via web-interface. See the Wiki tab for detailed information. Any questions are welcome: contact@engitex.org -

StFFT
FFT on Structured text
Fast fourier transform algorithm written on IEC-61131-3 Structured text programming language for programmable logic controllers. Algorithm is split-radix FFT. StFFT is iterative contrary to more common recursive approach. Iterative solution was chosen because PLCs don't have support for recursion. For compatibility with as many as possible PLC models, algorithm have dependency only on sine and cosine functions. Dual licenced under LGPL and Commercial licence. For commercial licencing contact tamitech@tamitech.fi Author Jaakko Pasanen -

J-X-Way UNI-TE
Java library for X-Way and/or UNI-TE communication.
PROJECT HAS MOVED HERE: https://github.com/Elektordi/x-way-uni-te X-Way and UNI-TE (also used in Unitelway) are communication protocols for old Schneider Electrics PLCs (Programmable Logic Controllers), formerly "Modicon Télémécanique". The aim of this open-source project is to create a Java library to send and receive such data, because there is actually no open-source project at all in this field. Keep in mind that those protocols are old and not maintained anymore by any company, but still used in many old PLCs installations.
