Features

No Special Unit, Tool, nor Middleware Required
 No special Unit is required for the DB Connection function. You can use the NJ/NX -series CPU
Units.
 No special tool is required for the DB Connection function. You can use Sysmac Studio.
 The server does not need any special middleware for connection to the NJ/NX -series CPU
Units.
Easy Access to the DB
 The SQL operations such as INSERT and SELECT can be easily executed.
 No special knowledge of SQL statements is required.
 Variables for DB access can be defined just by creating a structure for the table that you want to
access.
 You can easily control the execution timing and prepare the write values because the SQL
operations can be executed by special instructions.
Recording of Operation Logs
 You can save the execution result logs of special instructions and processing (i.e. internal SQL
statements) as a log file into the SD Memory Card mounted in the CPU Unit. Also, you can
check the logs using Sysmac Studio or FTP client software.*
* For saving the log files, an SD Memory Card is provided with each Database Connection CPU
Unit. The SD Memory Card can be also used for any purposes other than DB Connection
functions such as reading from and writing to the files in the SD Memory Card using
instructions.
Fail-safe Design against Errors and Power Interruption
 You can spool the data (i.e. internal SQL statements) if the data cannot be sent due to an
information exchange error with the DB, and execute the processing when the communications
are recovered from the failure.
 You can automatically save the Operation Logs by shutting down the DB Connection Service
when turning OFF the power supply to the CPU Unit.
Making a Library of DB Access Function
You can provide and reuse the special instructions as a library file by describing each special
instruction as a user-defined function block.
