Java integrering med PLC

Sammanfattning: Digitization has been given a greater role in the monitoring and control of a processing plant. This trend will grow globally to achieve a smarter production chain that generates ecenomic profits. The purpose of this thesis was to develop an existing process that respresents an automated drilling station. THis i scontrolled by integrating Java-netbeans software into the PLC hardware with a user interface that can read the data flow of PLC.The drilling station is controlled by PLC. This work describes the possible methods for achieving integration between Java-netbeans and PLC.  The essential part of the work was literature study, programming of source code and programming of PLC. This work achieved all the objectives.
