Define tag type keywords and attributes

Tag records begin with a keyword line that identifies the type of tag. Each tag keyword includes a unique set of attributes to specify the characteristics of the data associated with the type of tag.

In the following example, the :IODisc keyword identifies the I/O discrete tag type. The remaining values in the keyword line identify the attributes of the data associated with an I/O discrete tag. This example shows the contents of the file with Notepad in its native comma-delimited string format.

:IODisc,Group,Comment,Logged,EventLogged, EventLoggingPriority,RetentiveValue,InitialDis, OffMsg,OnMsg,AlarmState,AlarmPri,DConversion, AccessName,ItemUseTagname,ItemName,ReadOnly, AlarmComment,AlarmAckModel,DSCAlarmDisable, DSCAlarmInhibitor,SymbolicName

Beneath the tag type keyword line, individual rows specify the tags of that type with a set of attribute values. In the following example, the HDWStatus tag belongs to the I/O Discrete tag type in the import file.

"HDWStatus","$System","",No,No,0,No,Off,"","",,1,Direct,"HistdataViewstr",No,"Status",No,"",0,0,"",""

The record uses quotation marks to identify a blank string.

The following figure shows the same import file data in an Excel spreadsheet. The Comment cell is blank because no tag comment is specified in the import file.
