SEMI E37: Specification for High-Speed SECS Message Services (HSMS) Generic Services
Defines an Ethernet (TCP/IP) communication handshake and transmission protocol. This is the customary communication channel between a factory host and all the equipment it must connect with, via SECS-II messaging. The standard describes connection and transaction procedures, as well as how communication failures should be handled. Once communication has been established, SECS-II messages can be exchanged between two entities.
A number of our products support SEMI E37.
