Abstract: Various embodiments of the teachings herein include an information processing method. An example method includes: generating a workflow in an OT domain described by using a common information model based on an instruction input by a user, wherein the workflow defines an operation to be performed by a workcell in the OT domain; converting the workflow into a function block program described in a domain specific language; and deploying the function block program described in the domain specific language to runtime of a main controller of the workcell for execution, to control an OT device in the workcell to perform, based on the workflow, the operation.

Abstract: Some embodiments of the teachings include: establishing a foundation layer comprising an OT domain low-code development tool, runtime, and a public information model, and an OT domain workflow generated by the development tool deployed on the runtime using the public information model; establishing a domain layer depending on the foundation layer, the domain layer comprising a field bus, a domain protocol, and a device tree of an application domain, the device tree comprising a connection relationship between devices; and establishing a user case layer that depends on the domain layer, the user case layer comprising user-defined function modules, and the user-defined function modules capable of being converted into the field bus, the domain protocol, and the device tree in the domain layer, wherein data obtained from a data platform is transmitted between the user case layer and the domain layer and transmitted between the layers using the model.

Abstract: Various embodiments of the teachings herein include a device control method. An example includes: receiving a first workflow generated by an OT domain low code development tool; generating a micro-service corresponding to the first workflow used for defining an operation to be performed by one working unit in the OT domain; receiving a parameter value of the micro-service configured by an IT domain code development platform; and generating a second workflow based at least in part on the parameter value of the micro-service configured by the IT domain code development platform, so each OT device connected to the working unit performs an operation according to the second workflow.

Abstract: Some embodiments of the teachings herein include an OT domain low-code development platform. An example development tool receives an instruction inputted by a user on a GUI, to generate an OT domain workflow. The workflow is used to define an operation to be performed by a work unit in an OT domain. The tool determines, according to the instruction, functional blocks comprised in the OT domain workflow and relationships between the functional blocks. For each OT device in the work unit, an operation to be performed is defined by a functional block an instance of an operation template of a category to which the OT device belongs. The operation template predefines an operation which can be performed by the OT device of said category. The tool generates the OT domain workflow according to the determined functional blocks and relationships between the functional blocks.
