1 Introduction
This document describes the SECS interface version 503.xx provided on the SIPLACE
S25HM, S27HM, HS50 and HS60.
The SEMI Equipment Communication Standard (SECS) is published by Semiconductor
Equipment and Materials International (SEMI). It defines a computer to computer
communications interface between a unit of factory Equipment and a Host Computer.
This Equipment complies to the SECS-II standard, all SECS-II message used in GEM are
implemented. The SIPLACE complies to the following versions of standards:
E5-1994 (SECS-II)
SEMI Document #2758, Line 1 Item #1 (The Year 2000 issue)
1.1 Changes from Host Interface Manual V503.02
Variable PCBSIDEINCENTERCONVEYOR VID 912006 deleted.
1.2 SECS-II Clarifications
SIPLACE GEM is Year 2000 compliant according to the new Year 2000 SECS-II Standard
(SEMI Document #2758, Line 1 Item #1).
The SIPLACE uses the following SECS-II conventions:
1.2.1 Data Format Types
Where the Standards permit a choice of data item types, the choice has been made as
described in section „Message Detail“.
For outgoing messages, the Equipment always sends Data Items of the exact format
shown. For some incoming messages, the Equipment „forgives“ minor host errors. For
example, the Equipment may accept a U1 Data Item where a U2 format was expected.
We recommend the Host attempt to use the formats shown.
1.2.2 Data Item Length Bytes
For messages sent by the Equipment, the number of length bytes in Data Items is always
the minimum required to contain the Data Item length.
For messages received from the Host, the number of length bytes in Data Items can be 1,
2, or 3, provided that the length parameter can accurately be specified.
1.2.3 ASCII Data
Unless otherwise specified, all ASCII data items must contain printable ASCII data—that
is, characters in the range 0x20 to 0x7E.
1.2.4 Multi-Block Messages
Wherever the Host is supposed to send a single-block message, this Equipment will also
accept multi-block format.
The maximum size for a single SECS message is approximately 1000 blocks (256,000
bytes).

1.2.5 Function Zero
The Equipment sends a Reply Message using Function zero (F0) according to the
requirements of the GEM Control State.
Wherever this Equipment expects a Reply message from the Host, the Host can send F0.
The Equipment will instantly abort the outstanding transaction. The Equipment will not
take any additional action.
1.3 GEM Standard
The SEMI Generic Equipment Model for Effective Factory Automation (GEM) is another
document published by SEMI. The GEM standard defines some useful conventions for
designing the communications interface on a unit of factory Equipment to improve
operations with a Host Computer. The SIPLACE complies to the following GEM
document:
1. E30-1994
1.4 GEM Compliance
This section clarifies which GEM functions are implemented in this Equipment. See
„GEM Compliance Statement“ on page 11.
The SIPLACE never sends S2F25 (Loopback Diagnostic) to the Host. It will send the
appropriate S2F26 in response to an S2F25 from the Host.
The SIPLACE never sends S9F13 (Conversation Timeout) to the Host. The Equipment
can be defined as having an „infinite timeout“ for conversations.
The SIPLACE never sends S10F7 (Multi-Block Not Allowed) to the Host. It will accept
incoming messages consisting of printable characters and a maximum size of 320
characters.
The SIPLACE will accept, but does not require the Inquire/Grant transaction
(S2F39/S2F40, S6F5/S6F6, S7F1/S7F2) for incoming primary multi-block messages.
