The following are batch commands supported by the DeltaV system:
Abort - This command invokes the aborting logic for applicable phases of a batch, to reach the aborted state. The operator cannot restart a batch after an abort command. Abort is an emergency stop.
Active Step Change - This command allows change between steps of a recipe.
Auto - This command enables automatic execution of a batch at the procedure, unit procedure, or operation level.
Clear All Failures - This command sets the FAIL_INDEX register of the phase logic or recipe to zero.
Download - This command is used where the same phase is active before and after a recipe transition. When issued, the Download register is set to True.
Force Shutdown - This command shuts down the selected batch, forcing it to the lost state, from which it can be restarted or removed from the Batch List. This command is only available from the Administer Batches tab on the Batch Application Manager Advanced dialog.
Hold - This command is usable for a batch in running or restarting state. Hold invokes the holding logic for applicable phases of a batch, to temporarily stop operation of a batch, and to reach the held state. This written logic should put the batch in a safe state, from which the restart command is usable.
Manual - This command disables automatic execution of a batch at the procedure, unit procedure, or operation level.
Pause - This command indicates that the PAUSE_REQ parameter has been set, enabling logic with a stepwise pause functionality to stop at programmed pause locations and wait for the resume command. This command is accessed from the Phase Control screen in Batch Operator Interface.
Reset (or Remove Batch) - This command transitions the system from aborted, complete, or stopped state to the idle state, releasing any equipment not properly released otherwise. This command is accessed from the Batch List screen in Batch Operator Interface.
Restart - This command is usable for a batch in either the held or lost states. Restart invokes the restarting logic for applicable phases, and then transitions to the running state.
Resume - This command causes a paused phase to start running again. This command is accessed from the Phase Control screen in Batch Operator Interface.
Single Step (or semi-auto mode) - This command allows a phase to transition to the paused state (phase mode parameter, not batch state) at each programmed pause transition and wait for a resume command. This command is accessed from the Phase Control screen in Batch Operator Interface.
Start - This command invokes the running logic for the phases of a batch, as determined by the recipe SFC.
Stop - This command invokes the stopping logic for applicable phases of a batch, to permanently halt the operation of the batch and place all equipment in a safe state (the stopped state). The operator cannot restart a batch after a stop command. Abort is an emergency stop.
