Integration of the OPC UA standard is new on the PITreader S. On the one hand, the use of certificates increases the security of communication between Server and Client. On the other hand, PITreader S expands the connection options to other manufacturers’ systems, which also “speak” OPC UA.
Of course, PITreader S can be used to implement the requirements of access management for plant and machinery. You’ll be familiar with this from the PITreader. Whether you require simple enables, implementation of authentication for specific functions or a complex, hierarchical permission solution, PITreader covers it all.

Safety and security functions in one system
The operating mode selection and access permission system PITmode combines safety and security functions in one system. The devices enable functionally safe operating mode selection and the control of access permissions on plant and machinery.
PITmode devices can be used on plant and machinery on which it is necessary to switch between different control sequences and operating modes. Each employee can be issued machine enables and permissions that correspond to his or her skills using coded transponder keys with RFID technology. The safe evaluation unit detects the specified operating mode, such as automatic, manual access under restricted conditions or service mode, then evaluates it and provides functionally safe switching. This prevents misuse and tampering, while protecting human and machine.
PIT Transponder Manager: Efficient administration of PITreader transponder keys and user data
Save yourself the complex and error-prone management of manually created lists: manage the transponder key PITreader key plus your user data quickly and simply in the new PIT Transponder Manager!
In just a few steps, you can write individual user permissions on a PITreader key thanks to the graphical interface on the PIT Transponder Manager. You can select whether to create users individually or to integrate them using the import function. Connect the PITreader to the PIT Transponder Manager and you benefit from the ability to read information directly into the integrated database – this saves time and avoids errors. Work even more productively using preconfigured templates, in which you can program complete permission sets with just one click. If necessary, you can use block lists to block users or lost PITreader keys.

Safety & industrial security solutions
The application examples in the following video illustrate the safety & industrial security solutions that can be implemented on your plant and machinery using PITmode fusion and PITreader.
Overview of PITmode models
PITmode fusion – the modular operating mode selection system
PITmode fusion is the modular version of the operating mode selection system. It consists of the reader unit PITreader with RFID technology and a separate evaluation unit (safe evaluation unit – SEU). The transponder keys are read and taught in the PITreader. The safe evaluation unit evaluates the selected operating mode and provides functionally safe switching between up to five operating modes. Safe permission management can also be solved entirely with PITmode fusion. By separating the components, PITmode fusion can be integrated flexibly into the design of existing control consoles and can be combined with existing pushbuttons.
PITreader – control of access permission
With PITreader you can implement tasks relating to access permissions for plant and machinery. The options range from a simple enable and authentication of specific machine subfunctions to a complex hierarchical permission matrix. The transponder keys are available in a writeable version and also with fixed, stored permissions. To protect against tampering, the RFID keys can be coded using PITreaders with company-specific programming. PITreader is flexible and can be used as a standalone device or in conjunction with a Pilz controller.
PITmode flex and PITmode flex visu – Operating mode selection with PITreader and Pilz controller
In conjunction with the small controller PNOZmulti 2 or the automation system PSS 4000, it is possible to use the PITreader not only to control access permissions but also to implement functionally safe operating mode selection. That’s because the safe evaluation unit used to read the selected operating mode is already available as a function block in the Pilz controllers. The operating mode is selected via a pushbutton (PITmode flex) or via touch input on a PMI panel (PITmode flex visu).

PITmode – the compact all-in-one device
With the compact all-in-one device PITmode, the pushbuttons for operating mode selection and the safe evaluation unit are integrated in one device. Operating mode and permission are displayed safely via LED. The individual key coding prevents tampering. Ideal for international use, the operating mode selector switch is also available with pictograms for machine tools.
