7.6 Port Transfer State Model
7.6.1 Port Transfer State Model Requirements
7.6.1.1 The purpose of the port transfer state model is to provided information to the host for the use in accessing
ports. This may permit the host and stocker to utilize ports that are in service while avoiding the use of ports that are
not in service.

7.6.3 Port Transfer State Definitions
7.6.3.1 OUT OF SERVICE — Transfer to/from this port is disabled and the port should not be used in any Transfer
command issued by the host. If a command is issued by the host which uses this port, it will not be rejected simply
because the port is in this state.
7.6.3.2 IN SERVICE — Transfer to/from this port is enabled.
7.6.3.3 The following are optional sub-states of the IN SERVICE state to provide information to the host for the
use in accessing ports. The information is generally obtained by the TSC via a low-level interface with the
connected equipment. The connected equipment should generally, though not required, follow the Load Port
Transfer State Model defined in SEMI E87. If these states are implemented, they are not required for every port.
7.6.3.3.1 TRANSFER BLOCKED — The state is neither READY TO LOAD nor READY TO UNLOAD.
7.6.3.3.2 READY TO LOAD — The port is able to accept (be loaded with) a carrier from the IBSEM equipment.
7.6.3.3.3 READY TO UNLOAD — The port is able to have a carrier removed (unloaded) by the IBSEM equipment.

8 Collection Event List
8.1 This section identifies data collection events and defines (Stream 6) suggested associated variable data items.
The host can use the report definition scenario defined in SEMI E30 to define reports at IBSEM defined levels. The
intent of this section is to demonstrate that certain suggested data is available at specific events.
8.2 Requirements
8.2.1 This standard requires all collection events listed in the SEMI E30 standard (according to the GEM
capabilities required per §13).
