10 Application Examples
10.1 Application of Modbus Slave
Application HMI controls the remote Ethernet device through IFD9506.
Steps
(1) HMI sends out the instruction.
(2) Set the IP of slave IFD9506 to “192.168.1.6”, station address to “7” and communication
format to “38400, 8, E, 1, RTU”.
(3) In the IFD9506 serial slave mode table, set the station addresses of the two devices to
“1” and “3”, both of their relay IP addresses to “192.168.1.5”.
(4) Set the IP of IFD9506 in master mode to “192.168.1.5", station address to “8” and
communication format to “38400, 8, E, 1, RTU”.
(5) HMI master and IFD9506 slave transmit data through RS-485.
(6) IFD9506 slave and IFD9506 master transmit data through Ethernet.
(7) The RS-485 terminal on IFD9506 master is connected to two devices, which are PLC
at station address 0x0001 and PLC at station address 0x0003. Assume the
communication format is “38400, 8, E, 1, RTU”.
