TestAlarm
An alarm is related to any abnormal situation on the Equipment that may
endanger people, Equipment, or material being processed. GEM allows the Host
to be notified when alarm conditions are detected and cleared.
ALID
Equipment Alarm ID
CEID
Collection Event ID
Collection Event
A collection event is a detectable occurrence significant to the Equipment that is
considered to be significant to the Host. GEM allows the Host to be notified
when a collection event occurs. This allows the Host to track the Equipment's
activity.
Data Values
Also known as Discrete Data. Meant to be temporary or ephemeral statuses that
disappear after an event is complete. Sometimes known as 'DVs' (Data Values),
'DVVALs' (Discrete Data Values).
Data Variable
(DV)
Data variables may only be valid upon the occurrence of a particular event. The
Host may gather data variable values from the GEM Equipment.
Equipment
An intelligent system which communicates with a Host and complies with the
GEM standard. In this manual it refers to an Asymtek dispensing system.
Equipment
Constant (EC)
Equipment Constants are settable by the Host. The Host may gather Equipment
constant values from the GEM Equipment. The Host may also set Equipment
constant values on the GEM Equipment to control the Equipment's behavior.
Fluidmove
The Fluidmove

or Fluidmove

®
software
application which controls GEM.
GCD
GWGEM Configuration Data (an ASCII file compiled for GWGEM).
GEM
Generic Equipment Model. The GEM (E30) standard defines the generic
behavior of semiconductor Equipment as viewed through a communications link
in terms of SECS-II messages communicated over that link. The GEM standard
impacts Equipment control and Equipment-to-Host communications.
High-Speed SECS
Message Services
(HSMS)
HSMS (E37) is a high-speed replacement and an alternative to SECS-I for
applications where higher speed communication is needed or where simple
point-to-point technology is insufficient.
HSMS defines a communication interface via TCP/IP suitable for the exchange
of (SECS-II) messages between computers in a semiconductor factory.
Host
The computer which is connected to, and communicates with, the Equipment via
the SECS interface. he GEM standard defines a set of messages the Host must
use when interacting with the Equipment. The Equipment communicates with
one Host, but the Host may communicate with multiple Equipment units.
