MELSEC iQ-R CPU Module Internal Database Manual

This document describes how the MELSEC iQ-R Series CPU module's internal database, installed on an SD memory card, enables direct management of production and recipe data without requiring an external computer, reducing hardware costs and improving data processing performance. It covers database operations via ladder program instructions (add, update, search, delete), access from Microsoft Access or Excel over Ethernet, and custom application integration using SQL and ODBC.
