Aspects of the present invention provide machines, systems, and methods in which industrial control systems may be secured from compromise and/or disruption via authentication and firewall. In particular, an industrial controller may: randomly generate an exchange key and send the exchange key to a client device in response to a transaction request originating from the client device; combine the exchange key with a locally stored pass key to produce an authentication code; and compare a challenge key received from the client device to the authentication code to determine a match between the challenge key and the authentication code. A successful match between the challenge key and the authentication code may allow the client device to further access the industrial controller using a common industrial protocol (CIP), and a failed match between the challenge key and the authentication code may prevent the client device from further access to the industrial controller.

Industrial protocol system authentication and firewall

A system software solution for controlling an enterprise which defines and illustrates the electrical, pneumatic, hydraulic, logic, diagnostics, external behavior, controlled resources and safety elements of an enterprise control system. The elements of the control system are encapsulated in objects of an object-oriented framework within a control assembly. The control assembly is the fundamental building block for providing object-oriented control of the enterprise. A control assembly component is a deployable control subsystem that provides an interface using a common object model that is configurable. The enterprise control system is used to define user interfaces including sequence charts that are updated in a substantially realtime manner utilizing the control assemblies associated with the generated code for the enterprise control system.

An editor apparatus for programming industrial controllers in relay ladder language, the apparatus used to provide RLL logic to control a machine axis. The apparatus includes a display for creating an axis behavior profile that represents input devices, output devices, actuators, and required movements. The apparatus gleans information from the profile and, based on the information, creates modules that include logic required to provide a program section for controlling the axis. A compiler then compiles the modules to provide an RLL program section to control the axis.

Axis editor for industrial controller programming

An editor apparatus and method for programming industrial controllers in relay ladder language, the apparatus or method used to provide RLL logic to control machine tool movements in a desired sequence. The apparatus includes a display for creating a bar chart image that represents all functions in a cycle and graphically illustrates all function contingencies. The apparatus gleans function, cycle and contingency information from the image and, based on the information, creates modules that include logic required to make each function contingent upon illustrated conditions. A compiler then compiles the modules to provide an RLL program section to control the cycle.
