    • When we simulate a plc program we have to manually input the changes in input(like magnetic reed switch)
    • For example when a cylinder goes from up to down reed turn OFF and reed down turns ON
    • Is there any program available where we can define such things that will turn on and off during the process automatically.

    that is not LVDT, it is a linear potentiometer... 

    read datasheet, it tells that max current through it is 10mA which will be no problem if you power it by 10VDC source. then you can use its output directly although that is not recommended. max wiper current is recommended to be less than 0.1uA.

    Ohms law states R=V/I = 10V/0.1uA = 100MOhm. No analog input on PLC has such high impedance. Usually they have 0.1-1MOhm.

    To properly use such device one would need buffer of some sort (voltage follower) with high input impedance.

     

     

    I connected it to a 12v SMPS and I got the input. But the value keeps deflecting. Do I need to connect ground to terminal AG (Analog 0v)?

    Could you suggest me such a     device?

    Thanks for your help

    Have you configured the PLC settings correctly AND ternsferred them to the PLC AND performed a power cycle.

    Analog input data for AD CH0 should appear in CIO 90.

    Could you please tell me how to perform power cycle. I am new to this. Thanks


  3. Hi,

      I am using Omron CP1E NA 20DTD with built-in ANALOG inputs and output. I know how to deal with digital inputs. But I have no idea about analogue input wiring and programming. I tried connecting gefran LVDT PY2 directly to an analogue input of plc. But the indicator light did not turn on.
    Do I need to use any signal conditioner or converter? The output of lvdt is 0 to 25volts.

    I HAVE ATTACHED THE DATASHEET OF LVDT.
