secsgem

secsgem is a python package to communicate with a host or equipment system in the semiconductor industry.

The use cases range from writing tests for implementations or features, simulations in development environments to complete host/equipment implementations. Some parts of the package can be used individually, for example HSMS can be used without SECS-II, or the streams and functions can be used with a different networking stack.

Currently there is no support for communication over serial port (SECS-I, SEMI E04). Only ethernet (HSMS, SEMI E37) is available.

HSMS, SECS and GEM are standards from SEMI.

• Carl Wolff for his sample TCP socket implementation

• Darius Sullivan for his gist on how to use the streams and functions with twisted

• Massimo Vanetti for his help on the equipment implementation
