I need to program a PLC where the input is the temp and relative humidity (RH) sensors readings. The output is switching ON air exchange fans and water cooling pumps.
Also, the controller will ON/OFF irrigation water pumps according to settings.
I have a clear description of the system's functional requirements. I can even draw flowcharts for the controller logic.
Also, I would like to program my laptop to become an HMI. I think Mitsubishi offers free download software for this requirement. Along with its reasonable price, that is what I prefer Mitsubishi PLC.
My budget is not generous and looking for a good, eager to work PLC programmer
