Abstract

Industrial controller modules are configured with security components that implement backplane-level security protocols, thereby preventing installation of unauthorized modular devices on the backplane of an industrial controller. When a modular device is installed in the controller's chassis and interface with the backplane, security components in the processor module or other supervisory module initiates exchange of authentication data with the modular device via the backplane. The authentication data can comprise one or more security challenges to which the modular device must respond correctly before the modular device is permitted to operate on the backplane. These backplane-level security protocols can prevent installation of rogue modules that may be used to collect proprietary control data or interfere with control processes.
