    Hello,

    A PLC is specific hardware as Moeller, Wago, ABB, ...
    A Soft PLC is a program that runs on a computer.

    When you install CoDeSys V2, a Soft PLC called "CoDeSys SP PLCWinNT" is installed too.

    Best regards.

    Hi,

    Do you means we can use the "CoDeSys SP PLCWinNT" as a PLC Controller on our PC?

    So We can make use our PC/Laptop to communicate/control with remote I/O?
    (provided if we have the protocol master card is installed on it, like profibus, deviceNet and CanOpen)

    Hello

    Yes of course you can use a PC as a PLC !
    Generally we use an industrial PC rather than a laptop.
    With communication boards, networks and input-output decentralized stations.
    You can use : Profibus, CANopen, Modbus RTU, Modbus TCP, ....

    But you should know two things :
    1Β°) there are two soft PLC : CoDeSys PLC WintNT is dependent on Windows and CoDeSys SP RTE is not dependant on Windows.

    2Β°) These are not free soft PLC. You need a licence to use. Without licence they operate in demo mode during two hours, and after they should be re-started

    Best regards.

    a soft PLC same as a PLC can have multitasks in one program.
    i prefer to have one program with 4 tasks, so the overview is better.
