MODBUS/TCP: application protocol assigns how to manage and pass data
Open M2M protocol designed for communication among various devices. The communication takes place by exchanging data messages between a client and a server in a master-slave mode.
Modbus can be used to transfer data over various networks and buses (master-slave)

Modbus/RTU is a protocol that uses the RS-485 bus. It is frequently used in industrial applications, such as when connecting PLCs and displays, I/O interfaces and so on.

Modbus/TCP extends the previous Modbus/RTU protocol and is used in LAN (Ethernet) networks. The advantage of Modbus/TCP is its openness and compatibility with a wide range of industrial devices. Disadvantages of Modbus/TCP include a total lack of any security.


In NETIO power control products, Modbus/TCP support in smart sockets means that each individual socket can be controlled from various PLCs, SCADA applications and so on. NETIO sockets are the slave, the central software is the Modbus/TCP master.
