SOFTWARE:
The program Gibitre-Press Logger permits to extract data from the PLC controller of the press and to record continuously the test conditions of the machine. The temperature and pressure (if pressure control option is installed) are recorded both graphically and numerically. All the data are stored in a text file which is automatically generated for each working day.
