    I need a good SCADA software to use with PLC.The important thing is that the software is good and cheap/free.It&quot;s also important that it has possibility to communicate with different PLC protocols, such as Modbus, Sbus, Profibus etc.You will show me examples of software (or you will make software), and you will work with this software for me.Long term work is possible.

    My project is to write a small piece of code in microchip assembly language for the 18F1220 microchip microcontroller. All that is required is to copy a register and send it to an external modem. This will require formatting the message to meet the external controller message format including a check sum.

    Hello,This project is about Green&quot;s function. You are going to find scanned pages in the attached RAR file. On page 10 [file name: &quot;entails the following.tiff&quot;], the procedure is shown in 4 steps. That procedure is to be followed and we are eventually going to get equation (2.21) on page 19 [file name: &quot;H2 k 2k.tiff&quot;]. To arrive at this equation, we need to get the first 3 steps on page 10 done [namely, scalar and vector potentials, quasistatic calculations and finding F1(kp) seen in equation (2.21) mentioned above]. After getting these, we are need to compute that integral in matlab.Please let me know if you have any questions.Thank you!

    Hello.I think about project on MCU for measuring alternating current, TrueRMS voltage, frequency and may be other function (cos phi?). Firstly i think about ten devices. It&quot;s should be cheap. I believe use LCD or 3-digit LED display.How much money do you like?If you have interest - little test.We use linear interpolation for measuring TrueRMS voltage. How many points need use for accuracy less than 0.5%? I can help with project, but i cant doing it self because i&quot;m very busy. I don&quot;t know really cost of project..
