In a preemptive priority based RTOS, priority inversion problem is among the major sources of deadline violations. Priority inheritance protocol is one of the approaches to reduce priority inversion. Unfortunately, RTOS like uC/OS can’t support priority inheritance protocol since it does not allow kernel to have multiple tasks at the same priority. Although it has different ways to avoid priority inversion such as priority ceiling protocol, developers still have some difficulties in programming real time applications with it. In this paper, we redesign the uC/OS kernel to provide the ability to support round robin scheduling and implement priority inheritance semaphore on the modified kernel. As result, we port new kernel with priority inheritance semaphore to evaluation board, and evaluate the execution time of each of the kernel service as well as verify the operations of our implementation.

一般使用PC Based Controller 都是當作現場設備的一種，也就是要接受 主系統的命令，做一些操作控制。以Modbus 來看屬于Slave 的角色，隨 時等待接收Modbus Master 的Query Message，然后依據內容做控制，最后 將控制結果以Response Message 回傳。本章將以ICP 7524 及ICP 7188E5 等 兩種設備分別設計Modbus RTU、ASCII 及Modbus/TCP 的Slave 應用程序， 讀者可以將此兩種程序的架構再延伸設計至各種實際應用程序。
