SEMI E37-0303
HIGH-SPEED SECS MESSAGE SERVICES (HSMS) GENERIC
SERVICES
NOTICE: The designation of SEMI E37 was updated during the 0303 publishing cycle to reflect the reapproval of
SEMI E37.2.
1 Purpose
HSMS provides a means for independent manufacturers
to produce implementations which can be connected
and interoperate without requiring specific knowledge
of one another.
HSMS is intended as an alternative to SEMI E4 (SECS-
I) for applications where higher speed communication
is needed or when a simple point-to-point topology is
insufficient. SEMI E4 (SECS-I) can still be used in
applications where these and other attributes of HSMS
are not required.
HSMS is also intended as an alternative to SEMI E13
(SECS Message Services) for applications where
TCP/IP is preferred over OSI.
It is intended that HSMS be supplemented by
subsidiary standards which further specify details of its
use or impose restrictions on its use in particular
application domains.
2 Scope
High-Speed SECS Message Services (HSMS) defines a
communication interface suitable for the exchange of
messages between computers in a semiconductor
factory.

IEEE POSIX P1003.12 — Protocol Independent
Interfaces (PII)
4 Terminology
API — Application Program Interface. In the case of
TCP/IP, a set of programming conventions used by an
application program to prepare for or invoke TCP/IP
capabilities.
communication failure — a failure in the
communication link resulting from a transition to the
NOT CONNECTED state from the SELECTED state.
(See Section 9.)
confirmed service (HSMS) — an HSMS service
requested by sending a message from the initiator to the
responding entity which requires that completion of the
service be indicated by a response message from the
responding entity to the initiator.
connection — a logical linkage established on a TCP/IP
LAN between two entities for the purposes of
exchanging messages.
control message — an HSMS message used for the
management of HSMS sessions between two entities.
data message — an HSMS message used for
communication of application-specific data within an
HSMS session. A Data Message can be a Primary
Message or a Reply Message.
entity — an application program associated with an
endpoint of a TCP/IP connection.
header — a 10-byte data element preceding every
HSMS message.
initiator (HSMS) — the entity requesting an HSMS
service. The initiator requests the service by sending an
appropriate HSMS message.
