Symptom and Scope
Using Digital Output - KUKA | prc in DynamoStudio can display Warning: Logic.RunCORE operation failed. The available evidence does not establish a KUKA controller, robot, firmware, or communications fault; it identifies the node's TOOL input as the relevant configuration variable.
Correct the TOOL Input
Leave the TOOL input unset, then run the operation again. This change resolved the reported failure. Do not substitute a tool identifier or configuration value unless the project has separately verified that value.
| Check | Required state | Expected observation |
|---|---|---|
TOOL input |
Unset | The operation runs without the reported Logic.RunCORE warning |
Verify the Result and Separate the Remaining Limitation
Confirm the correction by rerunning the same digital-output operation and checking whether the warning is absent. The evidence also reports that gripper opening and closing could not be simulated in this configuration. Treat that as a separate limitation: clearing the node error does not, by itself, prove that gripper motion simulation is available.
If the warning remains with TOOL unset, record the node inputs and exact warning text for further diagnosis. The evidence does not support a product-specific secondary workaround or identify an affected software version.
FAQ
How do I fix Warning: Logic.RunCORE operation failed in KUKA|prc?
Clear the TOOL input on the Digital Output - KUKA | prc node and rerun the operation. This input change resolved the reported error.
Does Logic.RunCORE operation failed mean the KUKA robot is faulty?
Not from the available evidence. The reported resolution was to leave the node's TOOL input unset, so verify that configuration before attributing the warning to KUKA hardware.
Can the corrected digital-output node simulate gripper opening and closing?
The report states that gripper opening and closing could not be simulated in this case. Removing the warning and providing gripper motion simulation are separate outcomes.
