Hi forum.

I have some counters with 2ms resolution. I want to ensure that Modbus master doesn't query anywhere near this 2ms (500Hz). At 19200 baud there are 19200 bits per second so I approximate size for the average query and response at 30 bytes or 240 bits and divide 19200 by this amount I get 80 (query/response per second). Are approximations and math correct ?

No

The baud rate of a connection refers only to the speed of data transmission. It is not related to the interval between query or response messages.
