当write_register()更通用(pyModbus)时,我应该使用write_registers()吗?

当write_register()更通用(pyModbus)时,您应该使用write_registers()。

write_register()和write_registers()都是Modbus协议中的写操作函数。它们用于向Modbus设备写入数据。

write_register()函数用于向Modbus设备的单个寄存器写入数据。它接受两个参数:寄存器地址和要写入的数据。该函数适用于只需要写入单个寄存器的情况。

write_registers()函数用于向Modbus设备的连续寄存器写入数据。它接受三个参数:起始寄存器地址、要写入的数据列表和可选的从站地址。该函数适用于需要写入连续多个寄存器的情况。

当write_register()函数无法满足您的需求时,您应该使用write_registers()函数。例如,如果您需要一次性写入多个连续的寄存器,或者需要写入非连续的多个寄存器,write_registers()函数可以更好地满足您的要求。

在腾讯云的云计算服务中,可以使用腾讯云物联网通信(IoT Hub)来实现与Modbus设备的通信。您可以使用IoT Hub提供的SDK和API来编写前端和后端代码,实现数据的读写操作。具体的使用方法和示例可以参考腾讯云IoT Hub的文档和开发者指南。

  • GPIOs and Go

    Recently, I decided that I needed a small heads up display for import things I kept forgetting, like the time until an event started or number of unread emails in my inbox. I wanted the display to be simple and bright so it would really catch my eye. I naturally started to look at seven segment displays. Four digit, seven segment displays are available in most hobby electronics stores and come in a variety of packages. What is most noticeable when comparing these packages is that the 12 pin, analog package is significantly cheaper than the packages with bus interfaces (UART, SPI, I2C, etc.) and less pins. I wasn’t using the majority of GPIOs on my Raspberry Pi Zero and being frugal, I decided to buy the analog package. What happened next was an exploration into how Go can quickly control GPIO pins to make the display actually work well.
