Encryption feature for programmable safety controllers
Wieland Electric has developed a robust encryption feature for its samos®PRO family of programmable safety controllers, providing machine design engineers a means to prevent unauthorized tampering with the intellectual property in their safety software programs. Customers use the standard samos®PLAN programming software to design the logic and hardware configuration of the machine. Once complete, the LogicProtect feature is activated and prevents the program from being viewed or altered in any way. The system even provides a confirmation that the encryption function has been implemented correctly.
