Database Access Instructions

The database access instructions add, update, obtain, or delete data with respect to the tabular data such as product and
production information managed as databases in the programmable controller.
These instructions construct a database from the Unicode text file that defines information such as a table configuration, and
operates the database thus constructed. ( MELSEC iQ-R CPU Module User's Manual (Application))
