The SECS/GEM (SEMI Equipment Communications Standard/Generic Equipment Model) Module enables Ignition projects and third-party applications to communicate with semiconductor fab equipment. The module is an implementation of the GEM standard (SEMI E30-0307), the SECS-II standard (SEMI E5-0712) and the HSMS standard (SEMI E37-0308).
The module is implemented as a host that can talk to one or more tools via equipment connections configured within the Gateway. While it has some built-in simulation functionality to aid with initial setup, the module serves as a host only, and cannot respond as if were equipment.
Communication with equipment is in the form of messages defined by the SECS-II standard and referred to as SECS messages or just messages. By use of a simple definition file, any SECS message (including custom ones) can be supported.
Once the module is installed, a new header is available under the Config section of the Gateway Webpage that allows you to configure connections to the equipment, or setup simulators that are used for testing.
