When you download, the downloaded information is not
automatically stored into the RSNetWorx for DeviceNet software .dnt
file. You must make sure you save any changes after you exit the
DeviceLogix Editor to ensure that any changes made to the schematic
are saved, including changes made as a result of an upload.
Forcing
The DeviceLogix Function Block Editor provides troubleshooting
capabilities by allowing you to force inputs and outputs that allow
you to verify the run time result of your logic.
To aid in troubleshooting and debugging of your schematic, you can
force hardware inputs and hardware outputs. No other inputs or
outputs can be forced within the Function Block Editor. Network
inputs can be forced in the device from where they originate. If you
exit the Function Block Editor with a force enabled, that force will
stay in effect until you remove it.
To apply forces, right-click on the input or output element you wish
to force. A pop-up appears that lists the forcing options .
TIP
You cannot use the Force function in offline mode.
TIP
If Logic Enable is Off (logic is not running in the product), the
Force function has no effect. In this case, if the Force value is
modified, it will not take effect until Logic Enable is On.
TIP
You do not have to be in Edit mode to use forces.
