| Abstract: | This paper introduced the principle of compiled and interpreted PLC and proposed a design approach for an uC/OS-II based compiled PLC system. This paper further discussed its task scheduling, memory distribution and task communications. Results show that it is a better approach for a PLC which has complicated control functionality and data processing program. |
