Encryption function for Wieland samosPro programmable safety controllers

Feb. 8, 2015 – Wieland Electric has developed a robust encryption feature for its samosPro family of programmable safety controllers, providing machine design engineers a means to prevent unauthorized tampering with the intellectual property in their safety software programs, it says.

Customers use the standard samosPlan 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. It provides an additional layer of security for machine safety controller programming, it notes, by preventing reverse engineering and theft of safety programming.
