Programming Example 2

Example of reading and writing bit 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 %MX0.0~%MX0.7 to Y0~Y7 in DVP12SE, then
reads the values in Y20~Y27 in DVP12SE and stores the read values in %MX2.0~%MX2.7.
