Synergy between safety and security

With PITmode Fusion, Pilz Italia offers a combined, modular and flexible system for the safe selection of the operating mode up to Pld (Programmable Logic Device) and the control of plant and machinery access authorisation.

By guaranteeing the highest standards of safety & security, PITmode Fusion enables the efficient selection of the operating mode and management access permits.
The solution consists of a PITreader unit with RFID technology and integrated Web server and a Safe Evaluation Unit (SEU).
Thanks to the modular design, PITmode can be integrated into the design of existing control consoles – allowing the use of the same buttons - thus allowing further optimization.
According to their training, authorized users receive the correct machine authorization via a coded RFID transponder key. Up to five safe operating modes (automatic, manual in limited conditions, maintenance, etc.) can be selected.
Once the key is inserted into the PITreader installed in the control console, the SEU detects the specified operating mode and ensures  functionally safe switching. In this way accidents, improper uses and evasion can be avoided, while users can benefit from a greater availability of their machines.
 
PITreader keys and reading units
The RFID keys are read and configured in the PITreader. To increase anti-avoidance protection, they can be coded specifically for each company, using a password-protected signature. Keys without the aforementioned specific code will be denied access.
Furthermore RFID and PITreader keys can be used to implement group-based rather than single permission management.
In this case, the various authorizations are transferred to all the members of the group, who receive the same access authorizations; this greatly simplifies the assignment and administration procedures of the latter, in particular in the case of companies with different production sites, this also at international level.
The PITreader unit can be used to control access permissions in a particularly flexible way, either as a standalone device or in combination with a Pilz controller, such as the configurable PNOZmulti system or the PSS 4000 automation system.
