Collection Event Name Event Description Required DVVALs or

Reports

CarrierIDRead A carrier identification has been performed by the stocker system. For

reads that occur at an Input port, the event shall come prior to the

CarrierWaitIn event. For reads that occur at CarrierWaitOut port

locations, the CarrierIDRead event and the CarrierWaitOut events for that

port shall be sent to the host in a consistent sequence (i.e. CarrierIDRead

shall always precede the CarrierWaitOut, or alternatively, the

CarrierWaitOut event shall always precede the CarrierIDRead event).

There are not dependencies with this event at any other location.

IDReadError All carriers related to an ID error situation have been dispositioned. This

event occurs automatically when the stocker places the carrier that

experienced the ID error to the pickup port (See Section 13.3.3).

10 Variable Data Items

10.1 The purpose of this section is to define the list of variable data item requirements for Stocker SEM equipment.

Values of these variables will be available to the host via collection event reports and host status queries.

10.2 Requirements

 All variable data items and data item restrictions defined in SEMI E30 are required on Stocker SEM equipment

(according to the GEM capabilities required per Section 13).

 All variable data items in the Stocker SEM Variable Data Item Dictionary for specific equipment classifications

are required for Stocker SEM equipment. The data item restrictions are also required.

 Some SVs in the Variable Data Item Dictionary are referenced by an “i” subscript (e.g., CarrierID

). The “i”

subscript denotes a specific instance of the SV. This is necessary since there is usually more than one instance

of such an SV active in the system at the same time (e.g., if there are 20 carriers active at the same time then “i”

could range from 1 to 20 for CarrierID

). Variable Data Items containing the “i” subscript should not have

Variable IDs assigned to them.

 All variable data items with a format of ASCII (A) shall be limited to printable characters in the decimal range

of 32 to 126, with the exception of the following non-permitted characters: “*” (decimal 42), “\”(decimal 92).

10.2.1 Variable data items are documented in the Stocker SEM Variable Data Item Dictionary using the following

format:

Variable Name Type Description Class Format Comments

Where:

Variable Name: A unique name for the variable data item.

Type: CV – meaning common variables, variables that are general to all vehicles.

CSV – meaning configuration specific variables.

Description: If class is DVVAL, then the description shall contain a statement of when data is valid in

terms of Stocker SEM events.

Class: The data type of the item.

Format: <SECS Message Language (SML) mnemonic>acceptable formats are SEMI E5 lists, ASCII,

floating point, unsigned integer or signed integer. A description of “ANY”, indicates that only

the above formats are acceptable and is left to the supplier to decide.

Comments: Any additional information pertinent to the variable name.

SEMI E88-1104

10.3 Variable Data Item Types

10.3.1 Equipment Constants (ECV) — The value can be changed by the host using S2F15. The operator may have

the ability to change some or all of the values. The value of an equipment constant may be queried at any time by

the host using the S2F13/14 transaction or Stream 6 reports.

10.3.2 Status Variables (SV) — The values are valid at all times. A SV may not be changed by the host or operator,

but may be changed by the equipment. A host or operator command may change an equipment status thus changing

a SV. The value of status variables may be queried by the host at any time using the S1F3/4 or Stream 6 reports.

10.3.3 Data Variables (DVVAL) — These are variables which are valid upon the occurrence of a specific collection

event, and may or may not be valid at other times depending upon the equipment. An attempt to read a variable data

item when it’s invalid will not result in an error, but the data reported may not have relevant meaning.

10.3.4 Variable Data (V) — This is a class of variable data which includes all the previously defined types of

variables.

required)
