In the era of Industry 4.0, manufacturing execution systems (MES) software plays a crucial role in supporting production planning, tracking and control. This thesis focuses on extending two MES software programs for two distinct companies, Lincotek and Robopac, in response to the evolving needs of managers, operators and modern manufacturing in general. The first phase of the project regards Lincotek's need for efficient data exchange with a certain type of machine involved in their manufacturing process. A novel architecture is implemented, supported by a dedicated database and a new workflow in the Opera MES software. The solution automatises the data transfer process, thus eliminating the need for manual data copying and ensuring data accuracy.
