Ethernet Communication Module IFD9506
DVP-PLC Operation Manual
4. The Modbus instruction of 6 bytes: 01 03 00 00 00 0A is written into D500 ~ D502 in the example.
5. After the EIPRW instruction is triggered by setting M100 to ON, the data are transmitted to IFD9506, then
I
FD9506 forwards the instruction data to the serial slave of station address 1 and meanwhile reads
10
r
egisters of data. Eventually, IFD9506 sends back the response data from the serial slave to AS300.
After the communication is completed (the value in completion flag D50 is 2), EIPRW will store the receive
d
data in the 10 consecutive devices starting from D500 as shown in the figure below.
