2. Sequence element
A sequence element is converted into a tag name with a station number identifying the
station.
Example:
xxxxxxSddss (dd: domain, ss: station)
Tag comment
A maximum of eight-character tag comments for CENTUM V and a maximum of 16 single-byte
character tag comments for CENTUM-XL are directly converted to tag comments (a maximum of
24characters)forCENTUMVPeldcontrolstations.Inaddition,ifCENTUMVusessingle-byte
Katakana characters, they are converted to double-byte Katakana characters.
Element number
Element numbers start with 0 for CENTUM V and with 1 for CENTUM VP systems. An element in
number0(zero)ismovedtonumber100bydenition.
Computational expression
Each corresponding tag is registered on the control drawing as a functional block. Computational
expressions are converted manually because they cannot be simply converted in such a way
that their data format is changed from the normalized data to engineering unit data. However,
the following conversions are made to existing computational expressions and left as comments.
Note that R4.01.60 or later supports normalization so the normalized data can be converted.
• Processdatarangesusedincomputationalexpressionsaredescribedascomments.(No
buffer ranges are described)
• Ifatagnameincludes“-”orstartswithanumericcharacter,specifyanaliastousea
tag name + item name (a maximum of eight characters) or AL01 ... in a serial number (a
minimum of eight characters) as aliases.
Station data link
• ConversionofCENTUMV,7SL-DT
7SL-DT converts the transmission buffer and the receive buffer to BDA-L and BDSET-1L
respectively and also converts inter-station communications to CALCU.
Ifthebufferinthe7SL-DTisdirectlyreferencedandsetbyanintra-listrelativespecication,
or the same data in the buffer are set and referenced in multiple sections, a manual
conversion is made.
• ConversionofCENTUM-XL,SDL
SDL converts the transmission buffer and the receive buffer to BDA-L and BDSET-1L
respectively and also converts inter-station communications to CALC to execute BDA-L,
CALCU, and BDSET-1L in order.
