Abstract: In an industrial control configuration, various instances can exist that are based upon a definition. A definition can be changed and thus it can be appropriate to alter related instances in accordance with the change. However, changing an instance can cause disruption in other actions even when the change is minor. Therefore, various standards can be used to determine if a change to an instance should be propagated automatically or at another time, such as after an operation. The determination can be based on artificial intelligence techniques, user preference, a defined rule set, user instruction, as well as other standards.

Abstract: Information related to an industrial control system can be disclosed graphically on a visual display. To traverse through different system portions, an organizational hierarchy can be used to enable a user to roll down into deeper level or roll up into a higher level. A user can input a choice of a level to view and the level can be disclosed to the user, assuming that the user has appropriate authorization to view the level.

Abstract: An industrial control configuration can be disclosed to a user as a specific representation, such as a physical layout of different units of the configuration. A user can seamlessly move between different representations, such as switching from the physical layout to a logical layout. The representations can provide real time information and disclose animations to a user that represent different states of a unit or generally of a layout.

Abstract: A system and method are disclosed for developing programs for operating industrial processes. The system includes an operator interface, and a computer coupled to the operator interface, where the computer includes a memory and a processor. The memory stores a first program and information concerning a plurality of templates within at least one library and a plurality of objects within at least one project that is representative of the at least one industrial process. The processor is configured to execute the first program to process information stored within the memory so that the processed, stored information can be operated upon by a second program. The first program is capable of performing at least one of (1) determining an identity of one of the second program and a third program that was employed to generate the information, and (2) selecting portions of the stored information for use by the second program.

Abstract: A method and system are disclosed for creating programs executable on an industrial controller to control an industrial process. The method includes providing a plurality of templates from at least one library, where each template has at least one respective control variable. The method also includes receiving selections of at least some of the plurality of templates, and identifying at least some of the control variables as replacement fields. The method further includes creating at least one interface mapping to link to the replacement fields, where the first and second templates linked by the interface mapping form at least a portion of a compound template. The method additionally includes instantiating an object using the compound template, where the object forms at least a portion of the control program.

Abstract: A system allows for transferring messages between microprocessor based devices, such as programmable logic controllers (PLC), and a host computer over an Ethernet communications network. At the host computer level, these messages can be directed globally or locally. The host computer can immediately obtain messages from a programmable logic controller without interruption of the execution of the PLC's ladder program. The host computer can also receive unsolicited messages from the PLC.

Abstract: A control system contains a communications network, a host computer and a programmable logic controller (PLC). The host computer includes prioritized alarm queues for receiving prioritized alarms from the programmable logic controller. Alarms fall into either a local or a global category, and each category supports three types of alarms: warnings, alerts or faults.

Abstract: A control system allows for transferring messages between a programmable logic controller and a host computer over an Ethernet communications network. The messages include a routing address specifying an originating drop number, a destination drop number, and a routing drop number. The system is responsive to the routing address for transferring the messages between the programmable logic controller and the host computer. The host computer can immediately obtain messages from a programmable logic controller without interruption of the execution of its ladder program. The host computer can also receive unsolicited messages from the programmable logic controller.

Each PLC further has an interblock gap timer to signal the PLC when its transmit time slice is to occur. The time slice consists of a block transmit time and an interblock gap time. The total update time has been optimized to engable efficient, high-speed transfer of blocks of data between the PLCs.
