ClientConnect Request to be a client for either control or data services. R Y —
ClientDisconnect Request to discontinue client relationship. R Y —
Delete Request by Control Client to delete a Substrate Object
(SEMI E39). (See ¶12.6.7 for detail.)

UpdateSubstrateObject Request by Control Client to create a Substrate Object and
p
opulate its attributes with the attributes provided. Also sent by
the STPO for unloading the substrate.
R Y Y
XfrCmdListRequest Request to send an ordered list of micro commands to be
returned individually to the IMM STPO to affect a substrate
hand-off.
R Y Y
XfrCommand Message sent by the Control Client to an STPO to request a
certain action (micro command) be performed. A response is
sent when the action has been completed.
R Y Y
XfrVerify Message sent by the Control Client to a STPO when all
necessary actions have been completed to effect a transfer of a
substrate and asking for confirmation.
R Y Y
XfrHalt Message sent by either partner to stop all activities. This
message ends the transfer procedure and requires manual
intervention to clear.

Name Definition Form
ClientDelete The minimum number of tables the client wants to be
able to be able to store prior to being notified by the
event TableStorageCapacityWarning.
Non-negative integer. A value of zero
disables this rule.

18.3 Message Detail
18.3.1 ClientConnect Service — This service is used by a prospective client to request a connection as a Control
Client or Data Client. If the request is as a Control Client, and there is already a Control Client connected, the IMM
shall reject the request. The IMM shall also reject the request if a client with the same ID is already connected or if
the required interface version can not be supported. Table 30 defines the parameters for ClientConnect.
