Sysmac NJ SQL Client Manual

This document describes the SQL client capabilities of Omron's Sysmac NJ controllers (models NJ501-1320, NJ501-1420, and NJ501-1520), which allow direct data logging to databases like Microsoft SQL, Oracle, IBM DB2, MySQL, and Firebird without middleware. It covers configuration via Sysmac Studio, SQL function blocks for ladder/ST programming, spooling for data loss prevention, and execution logging for troubleshooting.
