Issue

sCtl26 - Verify that when the control object is in the WaitForExecution state the cancel or SelectWithValue request is rejected with AddCause "Command-already-in-execution" (IEC 61850-7-2 Table 54)

Cancel is possible during WaitForExecution state, it will not always be rejected.

Proposal

Change WaitForExecution to WaitForChange, during which state cancel is not possible and will be always rejected with AddCause "Command-already-in-execution".

Discussion Created Status
I agree but I think it's good to add what happens if a cancel is received when IED is in WaitForExecution state.

We can create a new test case with:
sCtl27 - Verify that when the control object is in the WaitForExecution state the SelectWithValue request is rejected with AddCause "Command-already-in-execution" (IEC 61850-7-2 Table 54).

I propose:
sCtl26 - Verify that when the control object is in the WaitForExecution state the cancel request is accepted but Operate request is rejected with AddCause "Abortion-by-cancel" (IEC 61850-7-2 Table 54).
