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.

Namespaces

All classes can be accessed with their full module name or directly from the secsgem module.

>>> secsgem.format_hex("Hallo")
'48:61:6c:6c:6f'

>>> secsgem.common.format_hex("Hello")
'48:65:6c:6c:6f'

• 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
