推荐答案

您可以编写自己的代码。这并不困难。从学习开始： MODBUS规范 [ ^ ]。

假设您要将1写入地址250处的线圈。然后您必须在串行线上发送以下内容请求（假设lave地址为1）：

You might write your own code. It is not difficult. Start by studying : the MODBUS specifications[^].
Suppose you want to write 1 to the coil at address 250. Then you have to send on the serial line the following request (assuming the lave address is 1):

slv  fun   address    data    checksum
0x01 0x05 0x00 0xFA 0xFF 0x00 0x0B 0xAC

唯一棘手的部分是校验和计算。但是，只需谷歌搜索就可以找到可用的代码。

The only tricky part is the checksum computation. However, just Googling you could find available code for that.
