I have developed a basic HMI which will communicate with a slave over Modbus (RTU binary). I currently have the program connected to COM1 of my PC, with COM2 connected to Modbus View, a master/slave simulator program.
I am using 9600 baudrate, 8 data bits, 1 stop bit, no parity, Binary/RTU settings, and am sending messages such as
[01][01][00][00][00][02][84][03]
to the Slave (located in address 1).
I am not getting any kind of response, although the ModbusView screen does indicate that my messages Are being received. No action is taken in the registers/coils of the slave, and no message, error or otherwise, is being sent back to the Master.
Any ideas as to why this is happening?
Thanks!
