Update Cycle (1-6000 ms): Set the cycle time for the execution of data exchange.
Connection Timeout (1-6000 ms): if the target device does NOT respond within this set time, the connection
will be seen as timeout.
Support Read/Write Synchronization (Function Code: 0x17): By using specific Modbus function codes, the
master can perform both read and write operations in a single command to improve data exchange efficiency.
However, when configuring, you need to make sure all devices used in the data exchange support the
synchronous read/write Modbus function codes. Otherwise, upon receiving the command from the master, it
may result in read/write failure due to the inability to recognize the function code.

Read (
: Input: the section where the master reads data from a slave.)
The DVP-ES3/EX3/SV3/SX3 Series reads data from a remote device. Here you can set up the start address for both
master and slave, and then set up the quantity and the data type.

Write (
: Output: the section where the master writes data into a slave.)
The DVP-ES3/EX3/SV3/SX3 Series writes data into a remote device. Here you can set up the start address for both
master and slave, and then set up the quantity and the data type.
