Application libraries can be used in the PLCs. The requirements for the use of the function blocks of the application libraries and information and prerequisites for the general handling of application libraries are described in the application examples:

FTP client library

Using the “AC500_FtpClient” example library, an FTP client can be used in Automation Builder. The principles of the FTP protocol and how to use the FTP client library are described in the ‎⮫ application example.

HTTP library

In order to be able to use the PLC as a client for web services, the HTTP function block library can be used. Setup and use of the HTTP library are described in the application example ‎⮫ AC500 Webservices - HTTP Function Block Library.

MySQL library

With the help of the MySQL function block library, MySQL databases can be used to store and access the PLC data. Setup and use are described in an ‎⮫ application example.

MSSQL library

With the help of the MSSQL function block library, MSSQL databases can be used to store and access data of the PLC. Setup and use are described in an ‎⮫ application example.
