Hello dear Luiz Carlos Sacheto, I knew LDmicro nine or ten years ago and since then I have been using this wonderful software that revolutionized my professional life.
I am a maintenance professional in the textile segment and I make my own hardware (PLC) both for use in my work and in other environments. (automobiles, residential, eg :)
I don't see any problems or faults in LDmicro, even when using in an industrial environment!
Just my true testimony!
