The purpose of this thesis with the conversion of the industrial press for centrumbrick on Hoganas Bjuf AB was to improve the security for the work- and maintenance personnel. To improve the security a new control system containing a PLC based control logic and HMI was developed. The new control system will improve the work security for the maintenance personal because the operating voltage for sensors on the machine will be lowered to 24VDC. At the same time the new control system allows new safety precautions as a two hand control to be implemented. To test the functionality of the new control system a simulation environment was developed. The simulation environment was implemented on a microcontroller of the model Arduino Mega 2560. This microcontroller was programmed to reflect the manufacturing process in a realistic way. All the software that has been used to develop the PLC program, HMI and the simulation environment is described in the report. Software that has been used is GxWorks2, iX Developer and Atmel studio.
