I want to see the traffic(data communicating) between Modbus master and slave devices on PC (Serial Terminal or any Modbus software).
When I tried to connect Master to PC, I can able to see data communicating between them on Modbus Slave software. And I also tried to connect Slave to PC, can able to see data on Modbus Master software. But when i connect Master and Slave together, they are not communicating. i also tried to connect directly Tx-Rx of Master to Tx-Rx of Slave (Bypassing MAX485), then they are communicating. But when MAX485 comes between them they are not communicating.
I'm using:
MAX485
MODBUS 3-wire protocol
RS485 to RS232 converter
Thanks
