Why we need this?

Yes, it is hard to code in Fortran, especially when we want to use it to design customized components in PSCAD. One of the most difficulties is the lack of debugging tools. I have been working on PSCAD since 2015, and it is only until recently that I found how to display logs to the console, so I can finally know which line the code is currently running at. I hope this note can help make your life a little easier :)

Usage

Message (since v4.6.0)

This routine can be inserted to anywhere in the Script section to display messages, warnings, and errors.

CALL EMTDC_MESSAGE(ICALL_NO, $#Component, 1, 1, "Messages")

• ICALL_NO and $#Component are predefined and should not be changed
• 3rd argument indicates the type of messages: 0 for message, 1 for warning, 2 for error
• 4th argument should not be changed
• 5th argument is the content of message to display

Warning

This routine can be used to display warnings in any PSCAD version.

CALL EMTDC_WARN(ICALL_NO, $#Component, 1, "Messages")

• ICALL_NO and $#Component are predefined and should not be changed
• 3rd argument should not be changed
• 4th argument is the content of message to display

An example

Here is a minimal example with a single customized component. The only script is the message routine.

This routine will output warnings in the PSCAD console like this (I am using v4.6.0).

You can insert this routine in any place you are interested in within your own Fortran script to track the execution of your code. You can also play with messages and errors in the given example.

Good luck on your project and research!
