Outline of Modbus/TCP Protocol 

Modbus/TCP is a communication protocol that is used when performing communication 
with a general-purpose PC or PLC using TCP/IP protocol over a network such as 
Ethernet. 
Communication is performed via this communication protocol to read and write registers 
on the VZ20X and exchange data between connected devices. The VZ20X can be 
connected to IEEE802.3-compatible networks by a 100BASE-TX Ethernet connection.
