The system is 2 wire RS485. The slaves can't operate 4 wire RS485. I presume the turnaround delay as described would be attributable to the master (3-4mS). Each slave has a query /response overhead of around 38mS (+ waiting time)at 9600baud. This suggests the slaves are largely behind the requirement for a 100mS polling time.

STM32 uses MODBUS protocol in serial communication. The MODBUS protocol was used in a recent project, so I learned a little bit, and make a record here so as not to forget it later. If you want to use MODBUS, you must first know that it is the MOBUS protocol. Here we have to understand the meaning of the protocol first.
