This is an ongoing thread discussing common PSCAD and EMTDC build errors, their causes, and potential solutions. The list will continue to expand over time. Users are encouraged to share any errors they encounter in the comments so we can build a comprehensive reference for the community.
NOTE: Most error messages are clickable in PSCAD. Clicking an error message navigates to the source of the error.
Signal 'XXX' source contention at component [COMPONENT] ''.
Description
This error occurs when two or more component outputs conflict. For example, two output signals may have been assigned the same signal name.
Resolution
Rename the conflicting signals so that each output signal has a unique name.
Input port 'XXX' is floating. A signal source must be provided.
Description
A component is expecting an input signal but has not received one.
Resolution
Make sure that some sort of input signal is provided. If not sure what the signal should be, or still developing the case, one can use a dummy signal to input any value to resolve the issue.
Signal 'XXX' dimension mismatch -> Y != Z
Description
A component is expecting an input signal with dimension Y, but has recieved an input with dimension Z. Dimensions must match.
Resolution
Edit the input signal so that the dimensions match. Use dummy input constants to satisfy that input dimensions must match.
