When operating in server mode, GridLAB-D accepts main loop state control messages from HTTP clients connected on the server's port. All control messages are in the form of HTTP 1.1 requests with the standard query format:
The following control actions are recognized
- Resumes a simulation that is in a PAUSED state.
- Resumes a simulation that is in a PAUSED state as long as the timestamp datetime is greater than the current clock time. The simulation will pause again when the clock reached the datetime.
- Initiates an immediate server shutdown.
