Issue

For the synchro-check functionality it is necessary to cancel the command sequence after an oper_req command is given. In this case the synchro-check is running and waiting for the switch on conditions (frequency, voltage has to be within the permitted range) Relating to the given state machine this status is in between “ready” and “WaitForChange” waiting for Oper_resp +.

Proposal

GoE-meeting 28.10.04:
Final proposal
There is no possibility for Canceling a command as long as no Oper_resp+ has been received. New state diagram as a proposal for the next meeting will be prepared by Siemens.
GoE-meeting 1.11.04:
Proposal will be verified and comment by George via email.
