代码说明:

ModSim32和ModScan32两种Modbus 调试工具使用说明: Modbus采用主从式通信,日常使用较多的是Modbus RTU和Modbus TCP/IP两种协议。最常用的Modbus 通信调试工具就是ModScan32和ModSim32。 ModScan32用来模拟主设备。它可以发送指令到从机设备(使用Modbus 协议的智能仪表终端设备)中,从机响应之后,就可以在界面上返回相应寄存器的数据。 ModSim32用来模拟从设备。它可以模拟采用ModBus 协议的智能终端。主要用在HMI 组态开发中,通过ModSim32改变寄存器状态的值,模拟智能终端的状态变化,来观察HMI 画面的变化。使得画面的变量配置正确。

    1、单向通信 向甲方连续不断地发送变量a的值,未按键,a=0x0f,按键后根据按键确定a值;并将a的值取反从P0口输出,控制D0、D1、D2、D3相应点亮。乙方接收到数据并偶校验正确后,将接收数据取反从P0口输出,控制D0、D1、D2、D3相应点亮。 2、双向通信 甲方连续不断地发送变量a的值,未按键,a=0x0f,按键后根据按键确定a值;乙方未按键不发送,按键后将乙方按键得到的a*16发送;甲乙双方都将发送数据与接收数据相或后再取反,从P0口输出控制D0—D7相应点亮。 3、间隔发送 未按键,甲方不发送数据,按键后甲方每隔50ms连续发送4个字节:0xff、a、a、a。 乙方只在收到甲方数据0xff后的3个数据并验证相同时,才将接收数据*16发送。 甲乙双方都将发送数据与接收数据相或后,从P0口输出控制D0—D7相应点亮。(1. One-way communication The value of variable a is continuously sent to Party A without key, a = 0x0f. After the key is pressed, the value of a is determined according to the key; and the value of a is output from P0 port to control the corresponding lighting of D0, D1, D2 and D3. After receiving the data and checking it correctly, Party B will output the received data from P0 port and control D0, D1, D2 and D3 to light up accordingly. 2. Two-way communication Party A continuously sends the value of variable a without key, a = 0x0f, and determines a value according to the key after the key; Party B does not send the key without key, and sends the a*16 obtained by the key after the key is pressed; Both parties will send the data to or from the receiving data, and then retrieve the data and control D0-D7 from the P0 port to light up accordingly. 3. Interval Sending Without keys, Party A does not send data. After keys, Party A sends 4 bytes continuously every 50 ms: 0xff, a, a.)
