Modbus RTU communication delay time

Postby om_tech_support_JT » Wed May 27, 2015 7:07 pm

Q: Looking to use the AR data stored type driver (AC input) and controlling it via ModBUS. I want to read the position feedback. Can you provide me with the delay time between the query and response?

A: The delay of the query and response is based on the transmission waiting time + silent interval and the processing time. Below are the timing charts to reference. The timing charts are also shown in the operating manuals for our Flex, or network capable products. Increasing baud rate can help decrease delays.
