ICP DAS provides PAC (Programmable Automation Controller) Flash Memory Protection to secure controllers and data. In harsh multi-interference environment (such as: current interference), the data stored in the flash memory may be altered by interferences. This PAC flash memory write-protection features the hardware/software methods to fight against the interferences and ensure the PAC operation and the data correction.

The PAC Flash Memory Protection can be applied to all MiniOS7 based PAC by ICP DAS. iPAC and gPAC series provide a hardware write-protection switch Flash Lock. User can enable this protection function easily by switching the Flash Lock to Lock position after download program to PAC to prevent the flash memory from data change. I-8000 series (I-8xx7 and the I-8xx7-80M non-PCB V 2.7 of the iPAC) provide a software protection method. Users download and install a new driver to enable the flash memory write-protection to protect the controller and data.

ICP DAS PACs with more protection for the flash memory are the best choice of industrial automation controllers. They fight against the growing, ubiquitous interferences in the environment, and protect the customer's controllers and data effectively.
