INTRODUCTION
To Users of Model V700-L21
The V700-L22 is the CIDRW controller complying with the 2003 edition of the SEMI E99 standard. A V700-
L21 cannot simply be replaced with a V700-L22. If you wish to replace a V700-L21, bring the CIDRW
controller control program into line with the new stipulations as described in this manual.
■ Main Points of Difference with the V700-L21
• Addition of support attributes
The CIDRW attributes defined as CarrierIDOffset and CarrierIDlength in the 2003 edition of the SEMI
E99 standard have been added.
With the V700-L22, the user can now specify as attributes the position of the MID in the ID tag, and the
data length.
Refer to Support Attributes 130.
• Changes in message specifications
The 2003 edition of SEMI E99 adds a format definition for the message specification data item MID.
The specifications of the data item MID have changed in the V700-L22.
Refer to Message Specifications 66.
• Addition of a data area access function
The V700-L22 has added a function for specifying ID tag data area access destinations as offset
addresses.
The V700-L21 divides the data area into 8-byte units called segments, and reads and writes data to
each segment. Besides this, the V700-L22 also allows you to specify offset addresses referenced to
the first address in the ID tag data area, so that data can be read and written in units of one byte.
Refer to Message Specifications 66.
• Replacing a V700-L21 with a V700-L22
The following settings are required to replace a V700-L21 with a V700-L22.
(1) Set the attributes CarrierIDOffset and CarrierIDlength.
Set CarrierIDOffset to 0 and for CarrierIDlength set the data length of the data item MID specified
by the ID write request (S18F11). If there is a mismatch between the CarrierIDlength attribute and
the MID length in the ID write request (S18F11), a CE (communications error) occurs, and no data
is written.
(2) Change the MID to data comprising displayable ASCII characters only.
With the V700-L22, data that includes undisplayable ASCII characters cannot be read with an ID
read request (S18F9); an EE - execution error - occurs. Data including undisplayable ASCII char-
acters in the MID cannot be specified with an ID write request (S18F11).
With the V700-L21, the MID to be read or written is consigned to an area fixed at 16 bytes. If the specified data length in
the ID write request (S18F11) is less than 16 bytes, NULs are added in internal processing to make the total up to 16
bytes. In contrast, with the V700-L22, the accessible MID data occupies only the area specified by the attributes Car-
rierIDOffset and CarrierIDlength. Remember that data can only be read or written in the area specified by the attributes.
