控制模板系统软件简介控制模板的所有系统软件及用户组态软件均存放在模板中的存贮器中,包括: 初始化程序输入/输出转换及处理程序各类自诊断子程序各种功能算法模块子程序主控调度程序通讯及处理程序 1.初始化程序该程序的作用为在初次上电时或WDT中断时对整个系统进行各种初始化工作,使系统开始或重新开始正常工作。 2.输入/输出转换及处理程序该程序的功能为将模拟量输入信号进行A/D转换后成为内部数字量信号,将控制运算后的数字量信号进行D/A转换后成为模拟量信号输出;同时,对开关量信号的输入/输出进行处理。
Control Template System Software Introduction All the system software and user configuration software of the control template are stored in the memory in the template, including: Initialization program Input / output conversion and processing program Various types of self-diagnosis subroutine Various functions Algorithm Module Program Master Scheduler Communication and Processing Program 1. Initialization Program The function of this program is to initialize the whole system during initial power-up or WDT interrupt, so that the system starts or restarts normal operation. 2. Input / Output Conversion and Processing Program The function of this program is to convert the analog input signal into an internal digital signal after A / D conversion, and to convert the digital signal after the control operation into an analog signal output after D / A conversion ; At the same time, the switch signal input / output for processing.
