Security and access control are given top priority in the production process, as unauthorised users and operating errors can cause great damage. R. STAHL is the only manufacturer in the market offering its explosion-protected Thin Clients with RFID authentication for secure identification of staff with access authority for process control and data communication from the field. On the basis of three technology platforms, the Thin Clients have been designed to meet the different requirements of the chemical and pharmaceutical industries, the food industry as well as oil and gas production.
Additional logins in the automation system are no longer required due to the faster, direct RFID access control, which meets the current security requirements according to FDA and GAMP. It supports transponders with MIFARE, DESFIRE, EV1 or LEGIC Advant reader technologies. Unlike biometric processes, the contactless RFID technology is also suitable for hygienically sensitive areas where obligatory protective clothing makes authorisation via fingerprint or face recognition impossible.
R. STAHL's explosion-protected RFID readers have been certified for Zones 1/21 and 2/22. They are either available as separate units with a USB interface for panel mounting, or they are integrated directly into the operator enclosures or keyboards by the manufacturer. The Thin Clients designed for the oil and gas industry with the SHARK technology device platform and 21.5" touchscreens are also available with a RFID reader installed behind the front plate. User authorisation via RFID requires the installation of a suitable device driver in the control system software. On request, R. STAHL will provide cards and key fobs equipped with tested transponders for use in hazardous areas.
