第四步:软件选项及参数设置 A) 选择ComCapture软件的“协议捕获”功能项。 B) “串口配置”项:在“端口号”和“设备名称”下,填写准确的串口号和连接在该串口下的设备名称。 C) “通信参数”项:在“波特率”、“数据位”、“停止位”、“校验码”等选项中选择三菱PLC和POP-HMI互相通信的参数值:“9600、7、1、偶”。 B) “显示方式”项:勾选“不显示”。如不选中“不显示”项,则在软件右侧的空白区域内将显示PLC和HMI之间的通讯信息数据值。且随着通讯时间的增加,显示的数据越来越多,终将影响用JB_HMI画面组态软件将编辑好的HMI工程文件由串口COM1下载至POP-HMI文本中。 D) 通信的速度。如果选中“HEX”选项,PLC和POP-HMI之间的通讯数据将以十六进制数显示,以方便使用者查看。 E) “串口控制信号”项:按PLC的串口信号实际情况选用;三菱PLC选取默认方式,无需选中。 F) “数据保存”:默认为不保存。如需保存通信过程的数据,选择“启动”,捕获的数据将被保存。数据文件的保存路径和文件名默认为ComCapture软件安装目录下的ComCapture.txt,也可以自行更改保存路径及文件名。鼠标移至默认路径上,点击左键,输入文件名,即可输入新的保存路径和文件名。 第五步:程序调试 A) 在ComCapture软件画面的右下方中,用鼠标点击“启动捕获和显示”项。此时如果通讯参数设置完全正确,通过PC上的ComCapture串口软件,将在PC串口COM1和COM2之间搭接一条“虚拟电缆通道”,而分别连接在COM1、COM2口的POP-HMI和三菱PLC将通过该PC软件虚拟通道进行间接的通讯连接;这就避免了直接用通讯电缆连接PLC和HMI设备给调试带来的不便。 B) 测试使用POP-HMI和PLC的功能是否满足设计要求;如果POP-HMI或PLC的程序达不到设计要求需要修改PLC程序或POP-HMI工程文件,您只需鼠标点击“停止捕获和显示”,COM1和COM2口即处于通讯断开状态。然后根据设计要求分别对PLC或POP-HMI进行程序修改,并回到第二步进行操作。 C) 程序修改完毕后,您只要再次回到第五步,点击“启动捕获和显示”项,即可调试修改后的PLC程序或POP-HMI工程文件。如果还要修改PLC和POP-HMI的程序,那就再次点击“停止捕获和显示”。如此反复,直至调试工作结束。 三、结束语   在三菱PLC和POP-HMI连接调试中,使用PC Windows平台下的ComCapture串口工具软件,在PC的COM1和COM2两个串口之间建立了一个虚拟的电缆通道,间接的连通了COM1和COM2上的两个串口设备(HMI和PLC);使得开发者可以在不必频繁拔插串口通讯电缆的情况下,任意修改不满足要求的HMI或PLC程序,极大的简化了开发者的调试工作。由于ComCapture串口软件具有串口通讯数据显示和存储功能,使用者还可以利用此功能对两个串口设备的通讯协议进行分析研究,从而得到该通讯协议的完整资料。以FX2N-32MR可编程控制器为核心,采用比例积分微分(PID)算法的温度控制系统。通过它的特殊模块完成硫化温度的采集、显示、分析和处理来实现固体火箭发动机恒温硫化温度的自动调节。保证产品质量,提高了生产效率和自动化水平。 关键词:可编程控制器、硫化、温度控制系统、PID 0引言used, which can be realized by using the built-in master-slave lifting function. If the general frequency converter is adopted, the above special functions must be completed by the control system, which will complicate the whole system and reduce the stability and reliability. The specific configuration is as follows: ■ the crane traveling mechanism adopts two frequency converters to drive one motor respectively. One is the master and the other is the slave. The master-slave application software is used to ensure the speed synchronization and load balance of the two motors and prevent the girder from twisting and rail gnawing. ■ the frequency converter of trolley mechanism adopts one frequency converter. ■ main lifting mechanism and auxiliary lifting mechanism, A special frequency converter for lifting is adopted respectively (ACC frequency converter). A photoelectric encoder is used for speed feedback and control detection respectively. ■ all frequency converters use chopper and braking resistance to realize braking function. ■ all frequency converters are equipped with various standard fieldbus interfaces. 3.2 the control system uses PLC as the core control device and industrial control Fieldbus to convert PLC, remote I / O and various mechanisms Frequency converter and touch screen are connected to reduce cable investment, wiring and maintenance workload and fault points. ■ remote I / O and touch screen are installed in the cab. Receive the instructions of the operator and display the information of various working conditions of the system,It is convenient for the operator to monitor, operate and facilitate the fault diagnosis and maintenance of the maintenance personnel. ■ PLC is installed in the control cabinet. Receive the status information of on-site detection devices and frequency converters, and control the operation of the system. ■ PLC control cabinet, frequency conversion control cabinet and resistance braking cabinet are placed on the girder. 4. Problems needing attention 4.1 environmental conditions the working environment of cranes is generally poor: conductive dust, water splash, corrosive gas, high ambient temperature, and high altitude in some cases. Both PLC and frequency converter are greatly affected by ambient temperature and altitude. Therefore, it must be used in strict accordance with relevant service conditions, and the protection grade and ventilation and heat dissipation mode of the cabinet must be
