Abstract
Control systems and methods for securing software images to be executed by the control system. In some examples the control system includes a control node, a concentrator node, and a security module. The security module may include a secured memory area that can hold software images. The security module may load a first executable image from the secured memory area to the control node. The security module may also load a second executable image from the secured memory area to the concentrator node. In some examples, rather than having a security module load the software images, the control node and concentrator node each include a secured area of memory where their respective software images reside. Each of the control node and concentrator node may load the software images from their respective secured areas of memory.
