Publication number: 20260236258Abstract: Variable extraction and mapping for programmable controllers is provided. An example method includes requesting, by a device remote from the programmable controller, a transfer to and storage in a memory of the device, of the instructions configured for effective use of the programmable controller. The method can include transferring and storing of such instructions into the memory. The method can include ingesting the instructions and a predefined set of reference variables into a model to generate a mapping between variables of the instructions and the predefined set of reference variables. The method can include using the mapping to adjust the instructions to operate based on an interface with a control mechanism. The method can include transferring control of the programmable controller to the updated instructions by transferring the updated instructions to the programmable controller.Type: ApplicationFiled: February 6, 2026Publication date: August 13, 2026Applicant: H2OK Innovations Inc.Inventors: David LU, Annie LU, Hu DOU, Edward Jitong LIU
