my project is about the detection of power spikes using Mitsubishi PLC. I was told to use the analogue unit FX2N-4AD to read data of the current sensor ACS712 using the TO and FROM function in the GX IEC Developer which isn't tht big prob as the example prog are available in the data sheet. What happened was that the analogue unit available in the lab is FX2N-4AD-TC which is for thermocouple and can only detect temperature reading so i was no longer able to use the analogue unit.
The supervisor told me to skip the analogue unit and connect my inputs with the FX1N-40MR Microcontroller. As the FX1N-40MR-DS only accept the digital inputs so i designed the A/D converter and amplified the voltage to 24vDC as the requirement for the FX1N-40MR. I just wanted to know that in this case how can i read data of the current sensor from the digital inputs of FX1N-40MR.
I will be happy to answer any question and will really appreciate any answers.
Thanks alot
