SECS Protocol Specifications

A summary of the SEMI standards that relate to CIDRW is provided for reference when using this product.
However, since the SEMI standards are subject to revision, you should also refer to the actual standards.
• SEMI E99 THE CARRIER ID READER/WRITER FUNCTIONAL STANDARD
• SEMI E5 EQUIPMENT COMMUNICATION STANDARD 2 MESSAGE CONTENT (SECS II)
• SEMI E4 EQUIPMENT COMMUNICATION STANDARD 1 MESSAGE TRANSFER (SECS I)

Operation Model

Set the CIDRW Controller's mode switch to 0 and start the system. When the system starts, the initial
processing is completed first, then the system will operate according to the status defined by E99.
CIDRW status model
Operational status
Alarm status
Initial status
(INITIALIZING)
CIDRW Head status model
Operational status
OPERATING Operation in progress in the operating mode
IDLE
BUSY
MAINTENANCE Operation in progress in the maintenance mode
# Transitions according to state changes from the host device
No alarm Status in which there are no alarms currently in effect at the CIDRW Controller
or any of the connected heads
ALARM Status in which an alarm has occurred
• If a head in an abnormal status is detected during head detection in initial
processing, or no heads are detected. (The error will not be cleared until the
system has been restarted with the heads connected correctly.)
• When a head error is detected in communications with an ID Tag. (The error
will be automatically reset if it is cleared in subsequent processing.)
• A CIDRW Controller internal error has occurred.
This is the status during processing such as internal initialization/head detection after startup, which is
maintained until the CIDRW system is capable of its proper functions.
OPERATING Status in which the head is operating normally
IDLE
BUSY
NON-OPERATING Status in which a head check (IDRW Head, Link Unit) is necessary
(The CIDRW alarm status is the ALARM status.)
Status in which no processing is in progress at any head
Status when processing is in progress at any of the heads
Status in which no processing is in progress
Status in which processing is in progress
