N90 point type 21 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 E.
4-byte Analog Report
N90 point type 22 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 PI attributes listed below can be extracted.
