Modbus reading

I needs read code modbus but I didn’t understand how to do it, whereas in async serial I managed to read the values sent and received by the Modbus server and client.

@giampieroferrotti I’m glad to hear you were able to decode data using the Async Serial analyzer as a workaround!

First, can you help confirm if both Master and Slave communications are sharing a single data line? If so, this mode of operation is currently not supported by our built-in Modbus analyzer. We’re tracking this request here at the moment:

Otherwise, if you are attempting to decode any of the following Modbus modes in the image below, feel free to share your .sal capture file with me and we can take a closer look!
