ADP宏指令: ADP提供了一种既方便又功能强大的宏指令应用方式，使人机得以经由内部宏指令(Macro Function)功能执行数值运算，逻辑判断，流程控制，数值传递，数值转换，定时器计数器，自定通讯指令操作等等，由宏指令的使用可让人机不仅和PLC联机通讯，同时由另一通讯端口来执行同其它通讯设备联机，此功能不仅提供有效的系统整合同时成为最经济便宜的硬件应用架构。而且使用宏指令也可大大的减少PLC的程序容量，让PLC的控制精度及效率最佳化。-ADP macros: ADP provides a convenient and powerful way macro applications, makes machines to be through the internal macro (Macro Function) function implementation of the numerical calculation, logic to determine, process control, value transmission, numeric conversion, timing device counters, custom communication instruction operation, etc., by the use of macros makes machines not only with PLC-line communication at the same time by another communications port to perform with other communication equipment on-line, this feature not only provides an effective system integration At the same time become the most expensive hardware, application architecture economy. And the use of macros can significantly reduce the capacity of PLC programs, so that PLC control accurac
