Manual Allocation and Release

Manual Allocation takes precedence over Automatic allocation and Recipe allocation. Manual allocation refers to the allocation of equipment (unit and connection) by a user through the Equipment Allocation dialog box within Batch. Any unit or connection defined in the train assigned to the batch can be allocated with this dialog box. However only equipment that has an available equipment status (such as Clean or Dirty), an available equipment state (such as Ready), and is not allocated to another batch can be manually allocated.

Manually allocating a unit allocates and reserves only the selected unit. Manually allocating a connection allocates and reserves only the selected connection. Neither the source nor the destination unit is allocated when a connection is manually allocated. Units and connections that are manually allocated are released when the operator manually releases the unit or connection from the Equipment Allocation dialog box or when the batch is complete.

Manual allocation is especially important when running batches in Manual mode. Only the phases associated with manually allocated units or connections can be run. Furthermore, if a batch is started in Manual mode, there are no units or connections allocated. Units and connections must be allocated manually before any phases are available for processing.
