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.
