13 DATABASE FUNCTION
13.3 CPU Module Database Access (from External Device) Function
13.3 CPU Module Database Access (from External
Device) Function
The CPU module database access function operates a database, that is built in an SD memory card inserted into the CPU
module, from an application on a personal computer through the Ethernet port of the CPU module.
To use the CPU module database access function, install CPU Module Database Access Driver into a personal computer.
( CPU Module Database Access Driver Installation Instructions)
In the CPU module database access function, the CPU module operates as the ODBC server and the
personal computer operates as the ODBC client.
ODBC (Open Database Connectivity) is the standard API that allows applications to connect with the
database management system (DBMS) to acquire and write the data.
Before using the CPU module database access function, check the version of the CPU module and the
engineering tool used. ( Page 1008 Added and Enhanced Functions)
Usage procedure
This section describes the procedure for operating the database by using the CPU module database access function.
Construction of usage environment
■Engineering tool
1. Module parameter setting of the CPU module
Set whether or not to use the CPU module database access function, login name, and password in the module parameter of
the CPU module. ( Page 244 Built-in database access setting)
2. Update of the built-in database access setting in the CPU module
Write the module parameter to the CPU module, and then power off and on or reset the CPU module.
■CPU Module Database Access Driver
1. Obtaining CPU Module Database Access Driver
For CPU Module Database Access Driver, please consult your local Mitsubishi representative.
2. Installing CPU Module Database Access Driver
Install CPU Module Database Access Driver into the personal computer. ( CPU Module Database Access Driver
Installation Instructions)
The installer of CPU Module Database Access Driver has the 32-bit or the 64-bit version. Choose the installer
depending on the supported bit of the application (Microsoft Access, Excel, user-created application) used for
the CPU module database access function.
For example, when using Microsoft Access with 32-bit version, use the 32-bit installer of CPU Module
Database Access Driver even though the 64-bit OS is used.
Procedure Description
Construction of usage environment Construct the environment to use the CPU module database access function.
Database access setting Configure this setting to create or change a database of the CPU module.
Database operation Operate a database of the CPU module from a personal computer.
