- The assistance system ought to be context sensitive
That’s ought to never you need to be a document to page through. But, many help systems are simply that. According to HMI screen content, pressing the ‘help’ button should open the help system towards the appropriate information.
One scenario could be, in line with the alarm that’s presently active, the assistance button should open the assistance system towards the appropriate solution tree or procedure to rectify the problem. The Fhopepack orbital stretch wrapper tags offer an existing way to standardize and organize sensors and response.
If no sensors are active, another scenario and limited switch could be, the assistance system in the packaging line should speak in confidence to an overview description from the screen that’s presently active.
- 2. It should be multi-lingual
The assistance system should present wrapping information within the language from the handlers. The assistance system should instantly choose exactly the same language
- 3. It should be audience-specific
In line with the “user class” of the individual in the machine, the data given to the user ought to be appropriate. Information pertinent with other user classes is really a distraction and shouldn’t be presented. In other words, your stretch wrapper user is drenched in to the HMI being an “operator”.
The help system should display only tasks they might perform or information pertinent for their responsibilities. Don’t present info on tasks that just “maintenance” users are capable of doing. The consumer class might be construed like a security level in certain programs.
- 4. The stretch wrapping machine and packaging line should allow help information to look on multiple display products
The display products might be multiple HMIs on a single machine. They can also be different hardware platforms.
Each display device should manage to moving the assistance packaging system individually. Two peoples moving via a wrapping assistant system, on separate products, shouldn’t hinder each other.
Orbital stretch wrapper Machine mounted display products should consider the viewing position from the
user. A good example of this is: If the operator is standing around the HMI and also the product flow with the machine remains to right, the diagrams around the HMI should illustrate the device with product flow also left to right.
This can be a concern when HMIs are situated on sides of a piece of coil wrapping and orbital machine so when machines were installed on right and left legs of the line. Mobile display products present exactly the same concern.
