5.1 Operating Personnel
The HF80 Transponder Reader is designed to be operated by
specially trained personnel only. If you have doubts about
the qualification required, contact the manufacturer.
Operating the device without special skills can result in
damage to the reader and/or connected devices!
5.2 Introduction
The SEMI Equipment Communications Standard E4 (SECS-1) defines
a communication interface that is suitable for exchanging messages
between semiconductor processing equipment and a host. A host is a
computer or network of computers that exchanges information with the
equipment to perform/execute the production.
The standard does not define the data contained within a message. The
meaning of messages must be determined through a message contents
standard such as SEMI Equipment Communications Standard E5
(SECS-2).
This standard provides the means for independent manufacturers to
produce equipment and hosts that can be connected without requiring
specific knowledge of each other.
The SECS-1 protocol can be seen as a layered protocol used for point-
to-point communication. The layers within SECS-1 are the physical
link, block transfer protocol and message protocol.
It is not intent of the standard to meet the communication needs of all
possible applications. For example, the speed of RS232 may be
insufficient to meet the needs of transferring mass amounts of data or
programs in a short period, such as may be required by high-speed
functional test applications.
In a network, the roles of host and equipment may be assumed by any
party in the network. In this situation, one end of the communications
link must assume the role of the equipment and the other the role of
the host.
High-speed SECS Message services (HSMS) is intended as an
alternative to SEMI E4 for applications where higher speed
communication is needed or when a simple point to point topology is
insufficient.
