前言

本文分享一个自己编写的电机控制逻辑块。

一、功能概述

手动状态、自动状态、机旁状态、强制状态、检修状态自由切换；
具有启动超时报警功能；
手动状态下，按启动按钮启动，按停止按钮停止；
自动状态下，根据程序联锁要求自动启停；
强制状态下，跳过允许启动条件，直接启动；
检修状态下，自动停止，且按下启动按钮不允许启动。

二、单输出电机程序编写

1.创建自定义数据类型

在这里插入图片描述

2.创建FB功能块“单输出电机”

建立如下引脚变量：
在这里插入图片描述

3.编写程序

代码如下：
1.赋值

#HMI.Ready_DI := #Ready_DI;
#HMI.Locally_DI := #Locally_DI;
#HMI.Running_DI := #Running_DI;
#Start_DO := #HMI.Start_DO;

2.时间转换、启动超时判断、故障复位

#HMI.Fault_All := #Fault OR #HMI.Time_Out; //故障赋值
#HMI.Lcl_DO := #Locally_DI AND #HMI.HMI_Lcl; //有就地信号，且按下机旁允许按钮，才会显示机旁允许状态

#Start_Time := DINT_TO_TIME(REAL_TO_DINT(#HMI.Start_T_Set * 1000.0)); //输入1表示1S

#RUN_IEC(IN := #HMI.#Start_DO AND NOT #HMI.HMI_Stop AND NOT #HMI.#Running_DI AND NOT #HMI.Fault_All,
         PT := #Start_Time); //启动延时

IF #RUN_IEC.Q THEN
    #HMI.Time_Out := 1;
    #HMI.#Start_DO := 0;
END_IF; //启动超时输出

IF #HMI.HMI_Rst THEN
    #HMI.Fault_All := 0;
    #HMI.Time_Out := 0; //复位启动超时输出
END_IF;

3.检测信号上升沿

#P_HMI_Lcl(CLK := #HMI.HMI_Lcl);
#P_HMI_EmgManual(CLK := #HMI.HMI_EmgManual);
#P_HMI_Pause(CLK := #HMI.HMI_Pause);

4.手动状态显示

IF #HMI.#HMI_Manual = 1 AND NOT #HMI.#HMI_Auto AND NOT #HMI.#HMI_EmgManual AND NOT #HMI.#HMI_Pause AND NOT #HMI.#Lcl_DO THEN
    #HMI.#Manual_DO := 1;
    #HMI.#Auto_DO := 0;
    #HMI.#EmgManual_DO := 0;
END_IF;
//默认手动状态
IF NOT #HMI.#Auto_DO AND NOT #HMI.#Pause_DO AND NOT #HMI.#Lcl_DO AND NOT #HMI.#EmgManual_DO THEN
    #HMI.#Manual_DO := 1;
    #HMI.#Auto_DO := 0;
    #HMI.#EmgManual_DO := 0;
END_IF;

5.自动状态显示

IF #HMI.#HMI_Auto = 1 AND NOT #HMI.#HMI_Manual AND NOT #HMI.#HMI_EmgManual AND NOT #HMI.#HMI_Pause AND NOT #HMI.#Lcl_DO THEN
    #HMI.#Manual_DO := 0;
    #HMI.#Auto_DO := 1;
    #HMI.#EmgManual_DO := 0;
END_IF;

6.强制状态显示

IF #HMI.#HMI_EmgManual = 1 AND NOT #HMI.#HMI_Manual AND NOT #HMI.#HMI_Auto AND NOT #HMI.#HMI_Pause AND NOT #HMI.#Lcl_DO THEN
    #HMI.#Manual_DO := 0;
    #HMI.#Auto_DO := 0;
    #HMI.#EmgManual_DO := 1;
    #HMI.#HMI_Pause := 0;
END_IF;
IF #HMI.#HMI_EmgManual = 0 THEN
    #HMI.#EmgManual_DO := 0;
END_IF;

7.休止状态显示

IF #HMI.#HMI_Pause = 1 AND NOT #HMI.#HMI_Manual AND NOT #HMI.#HMI_Auto AND NOT #HMI.#HMI_EmgManual AND NOT #HMI.#Lcl_DO THEN
    #HMI.#Manual_DO := 0;
    #HMI.#Auto_DO := 0;
    #HMI.#EmgManual_DO := 0;
    #HMI.#Pause_DO := 1;
    #HMI.#HMI_EmgManual := 0;
END_IF;
IF #HMI.#HMI_Pause = 0 THEN
    #HMI.#Pause_DO := 0;
END_IF;
