本文阐述了可编程控制器控制系统中，通过ASCII模块，实现远程操作站与可编程控制器的连接，并开发了ASCII模块中的接口通讯程序。
This paper expounded that the long distance operating station connect to PLC control system with ASCII module, and edited the communication program stored in ASCII module.
引起性能问题的原因有很多种，比如应用程序的实现方式、应用程序的操作系统、系统使用的远程资源，或者所有这些因素的结合。
Performance problems can be related to how an application is implemented, its operating environment, the remote resources that the system USES, or all of these.
这是所有的远程过程调用(rpc)机制实现的操作语义，因为它是在过程性编程语言和面向对象的编程语言中的标准函数调用语义。
This is the operating semantic that all remote procedure call (RPC) mechanism implement since this is the standard function-call semantic in procedural and object-oriented programming languages.
