The SECS-II ( S EMI E quipment C ommunications S tandard, Part 2 ), sometimes called SEMI E5 , is a communication protocol used in the semiconductor industry between devices involved in manufacturing. Much like the protocols in the OSI model , SECS-II is a layer above SECS-I and HSMS . While SECS-I and HSMS define how the communications are transmitted (such as over RS-232C or Ethernet), SECS-II defines the format and content of messages that can be sent over SECS-I or HSMS.
33-576: The protocol is maintained by the SEMI organization, from which copies of the SEMI E5 standard may be obtained for a fee. The SECS-II defines the message structure between equipment and host. Most of the SEMI E5 standard is a large library of possible messages – a few of which have redundant functionality with different message structures. Most equipment support only a restricted subset of these messages. Some equipments define custom SECS-II messages that are not part of
66-578: A CD-ROM, and now standards are available online on an annual subscription basis. Today, more than 1,000 SEMI standards and safety guidelines are available to address all aspects of automated fabs.

660-632: The complementary secondary message. For most SECS-II messages, a secondary reply message is required. For example, if the host sends an S1, F1 (stream 1, function 1) message to request 'Are you there?', then equipment will send a reply S1, F2 message to indicate 'I am here'. Each SECS-II message exchange has a unique transaction ID number. The standards allow message interleaving where there is more than one open, concurrent transaction. The SECS-II standard also defines lists of allowed data types including ASCII, binary, boolean, 4 and 8 byte floating points, signed and unsigned integers of byte length 1, 2, 4, or 8 and
