RMSC Read
(N90 point type The conversion is the same as the other analog point types. RMSC is function code 68. Note that the CIU cannot be in monitor mode if the user wishes to read RMSC points. Seethe Troubleshooting section for details.
4-byte Analog Read
(N90 point type This point type is supported by the CIU04 only. It is handled like other analog point types except that the precision is higher (about 7 significant digits) and the range is larger (E to 3.4E38).
4-byte Analog Report
(N90 point type This point type is supported by the CIU04 only. This is one of the point types for writing from the PI Server to the Bailey control system. Analog values should be either PI Float or Int points. The range is from -E to E. The output is set to bad quality if the PI value is a system digital state code (such as
SHUTDOWN
or
OVER RANGE
).
Bailey Database Conversion
The Bailey MCS and OIS Operator Console configuration contains much of the information needed for the PI Point database. The MCS or OIS can be configured from
DBASE files on a personal computer. The same files can be used to create text files for use with
PICONFIG
or comma separated value (CSV) files for use with PI Tag
Configurator.
Start by entering DBASE and creating anew database with several of the same fields as the
MCSTAG.dbf
or
OISTAG.dbf
file. The following PI attributes can be extracted.
Tag
The field name in the MCS or OIS database is
TAGNAME
. The MCS or OIS field is 14 characters long.
Descriptor
The field name in the MCS or OIS database is
TAGDESC
. The MCS or OIS field is 32 characters long.
