1.6 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 Equipment complies with SEMI E30-1993.
1.7 GEM Compliance
The following items and Table 1-3 clarify which GEM functions are implemented in this Equipment:
The Equipment never sends S2F25 (Loopback Diagnostic) to the Host. It will send the
appropriate S2F26 in response to an S2F25 from the Host.
The Equipment never sends S9F13 (Conversation Timeout) to the Host. The Equipment can
be defined as having an “infinite timeout” for conversations.
The Equipment 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 Equipment 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-NT-100 is used by FmNT to meet the SECS standard.
