8.14.2.4 MODBUS TCP Data Exchange Example

Programming Example 1

Example of reading and writing word registers in the slave

Example explanation
1. The motion controller is the MODBUS TCP master, DVP12SE is the MODBUS TCP slave
and the IP address of DVP12SE is 192.168.1.10.
2. The motion controller writes the values in %MW10~%MW19 to D0~D9 in DVP12SE, then
reads the values in D100~D109 in DVP12SE and stores the read values in
%MW110~%MW119.
