TwinCAT 3 Database Server enables the exchange of data between databases and the TwinCAT system. PLC variables or direct values of the EtherCAT I/Os can be logged cyclically when changes occur or event-controlled by means of PLC function blocks. A TwinCAT 3 PLC library for the Database Server utilizes the object-oriented extensions of the IEC 61131-3. As a result, the program code is more structured and much simpler to extend. The command processing is also significantly more performant. Furthermore, a C++ interface is implemented for the Database Server. The main databases supported are Microsoft SQL, Microsoft SQL Compact, Microsoft Access, MySQL, Oracle, SqLite, PostgreSQL, MongoDB and InfluxDB.
