Security for network communications is internally generated by an industrial control system (ICS). The ICS is assembled in a known-good environment prior to connecting to another network. While in the known-good environment, one or more components of the ICS auto-negotiate () with other components, assigning () security tokens. These certificates are used to internally secure communications between the components prior to any connection to other devices and without relying on external provisioning of the security tokens during commissioning () of the ICS.

Industrial control system with internal generation for secure network communications

A system and method for simulating a stress or failure in a network of a plurality of simulated networked program logic controllers includes simulating a plurality of networked program logic controllers in a network, the networked program logic controllers each having network information defining a node, the network information being selected from a type of program logic controller, an I/O connected to the program logic controller and a type of connection for the program logic controller; providing an interface in communication with each of the networked program logic controllers for simulating a network error; and activating the interface for inducing one of a stress or failure in the network.

System and method for simulating a stress or failure in a simulated network of program logic controllers

A system and method for simulating a plurality of networked program logic controllers includes, in one aspect of the invention, determining if a configuration of networked program logic controllers exists; populating a configuration by creating a plurality of program logic controllers in a network if the configuration does not exist, the populating of the program logic controllers provided by use of a network view for collecting network information; and interacting with at least one of the program logic controllers to simulate a networked program logic controller.
