Certain exemplary embodiments can provide a system, which can comprise a block processor. The block processor can be adapted to automatically render a list of automatically described modifications to a first version of a block of a software program adapted to control a programmable logic controller (PLC). The first version can differ from an original version of the block.

Systems, devices, and/or methods for managing program logic units

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.

System and method to simulate a plurality of networked programmable logic controllers

Embodiments of a system, method and computer program product are described for instantiating additional programmable logic controller (PLC) functionality. In accordance with one embodiment, an extension for a PLC may be identified and loaded into a memory space of the PLC. The loaded extension has an initialization interface that may be exposed to the PLC. When the initialization interface is invoked, functionality of the PLC may be passed to the extension as at least one parameter of the invoked initialization interface. The extension can then be initialized utilizing the passed functionality.
