The invention provides a process layer communication configuration method for a control protection apparatus of a converter station. The method comprises the steps of setting a corresponding CFC graphic function module for each user function module; performing configuration and programming on a communication demand in a graphic language mode; downloading codes generated by compiling a graphic program to a downloading region of the control protection apparatus; and according to the codes, calling the graphic program, accessing a protocol stack data region by adopting a unified interface, and performing secondary development on process layer communication data. According to the method, model files in a communication program are organically coupled together with application development, so that the difficult problem of simultaneous modification of the model files, applications and firmware is avoided, and secondary programming and implementation of the applications are realized; and meanwhile, the function modules are released after being tested, and repeated calling is simple, so that a large amount of test work in a conventional development mode is avoided, and the system stabilityand reliability and the application development efficiency are improved.
