Request DCS Modbus protocol format

2019-07-24View Original

Thread Content

I plan to create a front-end unit for collecting temperature data using PT100 thermistors, with communication via the 485 protocol to upload the data to the DCS. I need the DCS to use a Modbus protocol format; for example, the DCS should send me commands that trigger the data collection and uploading of temperature values

The agreement is simple; just use Baidu. If you can write the program yourself, why worry about the protocol?
