The Equipment sends a Reply message using Function zero (F0) according to the requirements of the
GEM Control State.
Wherever this Equipment expects a Reply message from the Host, the Host can send F0. The Equipment
will instantly abort the outstanding transaction. The Equipment will not take any additional action.
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
