1.3 GEM Standard
The SEMI Generic Equipment Model for Effective Factory Automation (GEM) is
another document published by SEMI. The GEM standard defines some useful
conventions for designing the communications interface on a unit of factory
Equipment to improve operations with a Host Computer. The GES-1993 complies to
the following GEM document:
 E30-1993
1.4 GEM Compliance
This section clarifies which GEM functions are implemented in this Equipment. See
"GEM Compliance Statement" on page 7.
 The GES-1993 never sends S2F25 (Loopback Diagnostic) to the Host. It will
send the appropriate S2F26 in response to an S2F25 from the Host.
 The GES-1993 never sends S9F13 (Conversation Timeout) to the Host. The
Equipment can be defined as having an "infinite timeout" for conversations.
 The GES-1993 never sends S10F7 (Multi-Block Not Allowed) to the Host. It
will accept incoming messages consisting of printable characters and a maximum
size of 320 characters.
 The GES-1993 will accept, but does not require the Inquire/Grant transaction
(S2F39/S2F40, S6F5/S6F6, S7F1/S7F2) for incoming primary multi-block
messages.
GWGEM Software Model GEM-W4-100 is used by FmNT to meet the SECS
