    The D2-240, D2-250, D2-250-1 & D2-260 CPUs support bit override.

     

    The D2-230 does not support override.

     

    You must use a K-Sequence or Ethernet Link to use overrides, a DirectNet link will not support overrides

    • To set the bit override option

     

    • Go to the VIEW>OPTIONS from the DirectSOFT menu bar.
    • Go to the data view tab and check bit override.

     

    • Select Current view and New views
    • From DEBUG>DATA VIEW>NEW/OPEN you can then select whether the particular bit can be (forced) overridden. When In edit mode
    • If you have turned bit override on for that element then you can use the on/off button to force the element.

     

    • Inputs LEDs will not turn on when an input is overidden
    • Output LEDs will turn on when overriden

     

    You can also turn bits on or off with Data View for a single scan to trigger events, but the PLC will update the image register on the next scan. The inputs will reflect their actual state and the outputs will be the result of the rung that controls them.

     

    • You can control outputs by loading a program that consists of an END statement only.
    •  
    • From DEBUG>DATA VIEW>NEW/OPEN you can then select the particular bit and use the on/off button to control the element.
    • You cannot control inputs.

     

    REMEMBER:

    If you leave an override bit enabled and return the machine to service it is still in the bit override mode.

    Be sure to turn override bits off before returning the PLC to service.

     

     

    The above may help you out.

    Regards,

    Garry

    Coming from A/B to Directsoft, I ran into similar confusion. In A/B parlance "forces" is most similar to what Directsoft calls "Overrides". Your screen shot shows a data view which will let you write a value to a memory location, which is not the same as forcing. It would be like opening up a data table in RSLogix and typing in a new value for a bit.

     

    If that memory location is also a real world I/O address the status will immediately be overwritten by the real input status in the case of an input address, or by your PLC code if any exists and is running in the case of an output.

     

    Go to the DirectSoft top menu, click PLC > Setup > Overrides.

     

    On that dialog box you can enter the addresses you want to force (override) and then enable the overrides there.
