Generating PLC code from CAD models
View Patent ↗Product data management systems, methods, and mediums. A method includes receiving a functional model, and identifying a plurality of elements of the functional model. Each element corresponds to one or more machine operations. The method includes identifying concurrencies between elements to determine at least one set of elements. The method includes creating an execution thread for each of the sets of elements. The method can include generating a rule-based programmable logic controller (PLC) program corresponding to the functional model, based on the execution threads.
1. A method performed by a product data management (PDM) data processing system, comprising:

identifying concurrencies between elements, by the PDM data processing system, to determine a plurality of sets of elements, each set of elements including elements that are dependent on each other and each set being independent of each other set;
creating an execution thread for each of the sets of elements, by the PDM data processing system, based on the identified concurrencies; and
generating a programmable logic controller (PLC) program corresponding to the functional model, based on the execution threads.
2. The method of claim 1 , wherein the PDM data processing system applies rules from a rules database to select PLC code from a code repository.
3. The method of claim 2 , wherein the PLC program is synthesized from the selected PLC code.
4. The method of claim 1 , wherein the PDM data processing system also creates a symbol table that includes known and unknown variables.
5. The method of claim 1 , wherein the PDM data processing system also identifies cycles in each set of elements.
6. The method of claim 1 , wherein the PDM data processing system also produces a schedule for each element.
7. The method of claim 1 , wherein the PDM data processing system also identifies the context of the at least one set of elements.
8. A product data management (PDM) data processing system, comprising:
at least one processor; and
an accessible memory, wherein the PDM data processing system is configured to:
receive a functional model;
identify a plurality of elements of the functional model, each element corresponding to one or more machine operations;
identify concurrencies between elements to determine a plurality of sets of elements, each set of elements including elements that are dependent on each other and each set being independent of each other set;
create an execution thread for each of the sets of elements; based on the identified concurrencies, and
generate a programmable logic controller (PLC) program corresponding to the functional model, based on the execution threads.
9. The PDM data processing system of claim 8 , wherein the PDM data processing system applies rules from a rules database to select PLC code from a code repository.
10. The PDM data processing system of claim 9 , wherein the PLC program is synthesized from the selected PLC code.
11. The PDM data processing system of claim 8 , wherein the PDM data processing system also creates a symbol table that includes known and unknown variables.
12. The PDM data processing system of claim 8 , wherein the PDM data processing system also identifies cycles in each set of elements.
13. The PDM data processing system of claim 8 , wherein the PDM data processing system also produces a schedule for each element.
14. The PDM data processing system of claim 8 , wherein the PDM data processing system also identifies the context of the at least one set of elements.
15. A non-transitory computer-readable medium encoded with executable instructions that, when executed, cause a product data management (PDM) data processing system to:
