ecat reset error

[wbzhong]

Hi, when we run "ecat reset" in the terminal, it reports an error:

error#20: illegal cmd: ecat 3

Could you give us some insights in the error?

That error is reporting that you typed ecat "3", not ecat reset.  It would seem that somewhere in the project there is a #define statement defining reset as "3", i.e. #define reset 3.  I would look in Global Includes first.  Or, ctrl-F to search in the project.

To add on a tiny bit--

 

While it is allowed, it is generally considered bad practice to have short words like that (reset, status, etc.) as #defines or variable names.

Any string which is either a command or part of a command (for instance, a variable named "AbsPos" would be considered part of Motor[x].AbsPosSf) should be avoided.

A better option would be to name your parameter "ResetVar" if it is a variable or "_reset" if it is not.

This way it is similar, but unique.

Thanks for the comments. It turned out that I named a PLC "reset", and this PLC was assigned an ID of 3 by the IDE.

You can name the PLC something like "ResetPLC" to keep the descriptive name and avoid the short word issues.
