This disclosure provides a device and method for implementing legacy and improved control functions in controllers, including but not limited to in industrial control systems and other systems. A method includes maintaining, by a device having a controller and a memory, a function library having a plurality of legacy control functions and a plurality of improved control functions. The method includes receiving a process to be executed by the controller. The method includes, when calling a function of the process, determining whether a device setting indicates that the function is to be executed by one of the plurality of improved control functions. The method includes, when the device setting indicates that the function is to be executed by one of the plurality of improved control functions, executing the function using the one of the improved control functions, and otherwise executing the function using one of the legacy control functions.

Legacy control functions in newgen controllers alongside newgen control functions

A method includes translating at least one application source code file associated with a legacy controller in a distributed control system to instructions executable by a controller simulation computing device, wherein the legacy controller is associated with a legacy operating system and the controller simulation computing device is associated with a second operating system different from the legacy operating system. The method also includes simulating operation of the legacy controller using the instructions and an emulation of the legacy operating system in the controller simulation computing device. The method further includes determining configuration data for the legacy controller during the simulated operation of the legacy controller. In addition, the method includes saving the configuration data to a configuration data file.

System and method for legacy level 1 controller virtualization

A system includes at least one processor configured to identify multiple nodes coupled to at least one network of an industrial plant, obtain configuration data from each of the nodes, parse the configuration data to extract specified information from the configuration data, and store the extracted specified information in a specified format. To parse the configuration data for each node, the at least one processor may be configured to generate a memory layout for the configuration data from the node, open a checkpoint file containing the configuration data from the node, and identify at least one point and header information for the at least one point in the checkpoint file using the memory layout. To identify the multiple nodes, the at least one processor can be configured to generate a network diagram of the nodes coupled to the at least one network and identify the nodes from the network diagram.
