Pilz PITmode fusion modular access permission system

PITmode fusion is a modular operating mode selection and access permission system. The modular system offers more flexibility for functionally safe operating mode selection and for the control of access permissions to plant and machinery.

PITmode fusion consists of the reader unit, PITreader, with RFID technology and a Safe Evaluation Unit (SEU). Its modular design allows PITmode fusion to be integrated into the design of existing control consoles. PITmode devices are used on plant and machinery in which users switch between a range of control sequences and operating modes.

Authorised users receive the machine access suited to their individual task on a coded RFID transponder key. Up to five safe operating modes can be defined, such as automatic mode, manual intervention under restricted conditions or service mode. The key is inserted into the control console, the SEU detects the specified operating mode and PITreader ensures functionally safe switching. Accidents, misuse and manipulation are prevented, and users benefit from higher availability of their machines.

To increase protection against manipulation, the keys can be coded with company-specific programmed PITreaders: that is, the keys include a password-protected signature. Any keys that do not have company-specific coding will be denied access. In addition, RFID keys and PITreader can be used to implement a group-based permission management. In this case the various enables are transferred to whole groups with the same access permissions instead of individual persons.

PITmode fusion offers functionally safe operating mode selection and access permission up to PL d.
