    Hello,

    I would like from a Python script.
    I want to add the plug-device of the EH-IOCA (Hitachi).
    there is someone who knows how to add plug-device via the Python script.

    Hello Rahied.

    The following steps are required:
    - Get the slot object, e.g. projectObject.find(...)
    - Plug the device into slot with slotObject.plug(...)

    For details about the parameters see the documentation of the ScriptEngine, which you can find in the sub directory "OnlineHelp" of the CODESYS directory.

    Thanks for your adversely word .

    Only I 'm not from there at all . I send my script there. Maybe there is someone who got a example . Or can tell me what to do .

    Hi Rahied.

    Please check the ID and the version of the device you want to plug! "51D_00000001_16 Digital Input_16 Digital Input" and "0" could be wrong.

    Also check the indentation of the "plug" line in your script because it was wrong when I opened it on my computer.

    I added a simple script as an example for you. It plugs all slots with the name "<empty>". The specified device required a module ID.</empty>

    Hi Rahied.

    The ID and version are correct.

    Since I'm not sure what you want to do, I modified your last script for two different scenarios:
    - Plug all slots with the same device
    - Plug only the first one

    Please remove the code of the unused scenario.

    Hello

    Sorry, I forgot that find() returns a list. Please replace the code with the following:

    objects = master.find('EH_IOCA', True) # Recursive search
    assert(objects and len(objects) == 1, "no object or more than one object with the name EH_IOCA")
    subnodes = objects[0].get_children() # Get all children
    

    Is there more than one slave below the master? if yes than you have to find a way to find the correct slave.

    BR

    You should use an editor which can display tabs and spaces, so you can see the problem. Here is how it looks in my editor using 4 characters tab with:

    Hi.

    What error do you get when you execute your script? Is it the text of the assertion or something else?

    Hi.

    The indentation of your script is still wrong. The indentation is important in python. Look at the screenshots.

    I modified your script to have the correct indentation and attached it. Please use a proper editor from now on.

    Hi Rahied,

    The Device is an EH_IOCA (with underscore).
    The name of the plugged devices cannot have a space. You should use e.g. "%s_%d" as device name to make them unique.
    Your import file (.txt) should have no empty lines at the end.

    Attached an example import file and script for plugging the modules in the Hitachi EH-IOCA EtherCAT slave.

    Maybe not perfect or complete, but for me this works.

    By plugging the device via a script a generated name is given to its structures and accessable variables (e.g. "%QX7.7", similarly when one has only plugs the device) but in GUI, I have the chance to map those addresses to variables.

    Is there a way to configure the plugged device configuration and I/O mapping ("xxx Configuration" and "xxx I/O Mapping" tabs)?

    I have some ADC/DIO/DAC "pins" configured and would like to map their variables and structures to one of the PRGs stored variables.

    Hi, etamgul,

    A scripting interface for the I/O Mapping is currently scheduled for the upcoming V3.5 SP8 release by the end of the year. (See CDS-37756).

    (Please note that the schedule may still change when other, more important issues arise.)
