HMI (HUMAN MACHINE INTERFACE)
The standalone supervision system is entirely developed with LabWindows/CVI an ANSI C IDE (integrated development environment) environment.
HMI(human machine interface), communicates with an industrial PC with touch screen technology, mounted on a panel on the electrical cabinet, used for supervision, diagnostics, management and analysis of production data and plant parameters.
Thanks to its simplicity of use, Arcos HMI allows a quick and intuitive setting of the working parameters through dialog boxes that can be activated by special buttons in touch screen mode, or by a simple mouse click in off-line mode.
The HMI organization is optimized to access and provide all the necessary information upon user’s request.
By accessing the main page of the HMI, users can access all the general information on the status of the plant through appropriate indicators. System pressure, operation of the auxiliaries, status of the safety devices, active alarms, status of the robot, status of the loaders, partial operating cycles, counters on request, timing of the operating cycles, etc can be displayed.
Based on this overall information, the user may decide to detail the information that does not meet his/her expectations.
The user may decide to display the alarms page simply by pressing on ” alerts “, then the computer screen changes showing any active warnings, a description of them and how to solve the problem.
The machine set-up instructions can be accessed simply by clicking on the desired icons, which are very intuitive and already give a sense of what you need to do, on how to start the various workstations in a manual cycle and with the possibility of choosing the working procedure, activate control mechanisms such as the compensation system, activate forced suction, for example, in order to access the island, reducing the risk of breathing residual dust left in the air, activate discharge belts, insert the loader inside the plant or extract it, set certain values of pressure, speed, etc., all without the machine being in automatic cycle operation; for example, pressing the button on the video start of the engine unit causes the engine to start; pressing the button on the stop of the unit causes the part of the system in question to stop.
The “synoptic” page indicates in a very intuitive way the pieces currently in production, the current number of pieces on the loader, the situation of some parts of the system and all in a high-performance way going to show and highlight by lighting or color change of the parts concerned in correspondence with the layout of the system, anomalies detected on the piece, anomalies detected on the pneumatic line, operating status of the work units, etc..
Much more information can be added, since our HMI. can be updated to reflect the specific needs of the application.
Finally, we shall mention a page provided by the HMI that takes into account the security requirements that each company must comply with, by adapting the particular restrictions of each user the ability to access and modify certain information.
Directly from the screens, the user can set up or manage his interaction, if necessary, with the production.
In summary, it is fair to say that all controls are extremely fast and intuitive thanks to the direct use of function keys associated with buttons that change functionality when the video screen is changed.
Other digital contents useful for the machine operator or maintenance technician can also be accessed from the HMI, such as the electrical diagram of the machine made of Eplan, printed in pdf “Adobe Acrobat” and access to the contents of the user manual.
